== Etymology ==
Various theories on the origin of the name Tehran have been put forward. Iranian linguist [[Ahmad Kasravi]], in an article "Shemiran-Tehran", suggests that Tehran, and Kehran mean "the warm place", and "Shemiran" means "the cool place". He lists cities with the same base and suffix and studied the components of the word in ancient [[Iranian languages]], and came to the conclusion that Tehran and Kehran meant the same thing in different Iranian language families, as the constant "t" and "k" are close to each other in such languages. He also provided evidence that cities named "Shemiran" were colder than those named "Tehran" or "Kehran". He considered other theories not consider the ancient history of Iranian languages, such as "Tirgan" theory and "Tahran" theory [[folk etymology]].<ref>{{Cite book |last=Yahya |first=Zoka |title=Karvand of Kasravi |publisher=Franklin |year=1978 |location=Tehran |pages=273–283 }}</ref>
 
The official City of Tehran website says that "Tehran" comes from the Persian words "Tah" meaning "end", or "bottom", and "Ran" meaning "[mountain] slope"—, the bottom of the mountain (ته کوه), referring to Tehran's position at the foot of the [[Alborz]] mountains.<ref>{{Cite web |author1=Behrooz, Samira |author2=Karampour, Katayoun |url=http://universityandheritage.net/SIFU/XII_Hanoi_2009/en/abstracts/html/14.html |title=A Research on Adaptation of Historic Urban Landscapes |date=15 November 2008 |access-date=18 June 2009 |archive-date=24 July 2011 |archive-url=https://web.archive.org/web/20110724115732/http://universityandheritage.net/SIFU/XII_Hanoi_2009/en/abstracts/html/14.html |url-status=dead }}</ref>
 
The most interesting toponymic theory of the place name Tehran is proposed by the Iranian linguist Zana Vahidzadeh (Dana Pishdar). According to Dana Pishdar, the etymological root of the place name Tehran should be sought in the ancient Iranian languages, such as Median and Avestan. Since the city of Rey and the area around Tehran were the largest cities in the Media region in pre-Islamic times, and since in Zoroastrian times they were considered a holy city and the center of a theocratic government similar to modern Vatican City, this suggestion does not sound illogical.<ref>Ahmad Kasravi, Kārvand-e Kasravi, ed. Yahyā Dokā, Téhéran, 1973. p. 273-83.</ref>


== Etymology ==
According to Dana Pishdar, the name Tehran consists of two lexical elements: "Teh" and "Ran." According to Pishdar, "Teh" in the ancient Median language means "honeyberry," and "Ran" means "foot of hills." Honeyberry trees used to grow in the northern parts of Tehran province. It is also mentioned in the Dehkhoda dictionary, where Dehkhoda explains it as follows: "Teh" is a noun used in Shemiranat and around Tehran for "the honeyberry tree."

The official City of Tehran website says that "Tehran" comes from the Persian words "Tah" meaning "end", or "bottom", and "Ran" meaning "[mountain] slope"—literally, the bottom of the mountain (ته کوه), referring to Tehran's position at the foot of the [[Alborz]] mountains.<ref>{{Cite web |author1=Behrooz, Samira |author2=Karampour, Katayoun |url=http://universityandheritage.net/SIFU/XII_Hanoi_2009/en/abstracts/html/14.html |title=A Research on Adaptation of Historic Urban Landscapes |date=15 November 2008 |access-date=18 June 2009 |archive-date=24 July 2011 |archive-url=https://web.archive.org/web/20110724115732/http://universityandheritage.net/SIFU/XII_Hanoi_2009/en/abstracts/html/14.html |url-status=dead }}</ref>
According to Dana Pishdar (Zana Vahidzadeh), the word Tehran means a place where the "honeyberry tree" grows. The suffix "Ran" is also found in many names of districts and villages in modern Tehran, such as Shemiran, Niavaran, Jamaran, Kasran, and Shahran, which are also not unrelated to each other. In Avestan and also in the Avesta, "Ran" had the meaning of "foot" and "plain," which is still associated with the name of the city of Rey. The Zoroastrian Medes called their largest and most important city Rhaga or Rey, which means the city located on the plain and at a foot. Therefore, the words "Rey" and "Ran" mean the foot of the mountain, and the etymological reason for this is the geographical location of Rey and Tehran, because both are located at the foot of the mountain and on a plain.<ref>Vladimir Minorsky, « Teheran », Encyclopædia Iranica 1, IV, p. 713-20.

Growing awareness of civil rights resulted in the [[Persian Constitutional Revolution|Constitutional Revolution]] and the [[Persian Constitution of 1906|first constitution of Iran]] in 1906. On 2 June 1907, the parliament passed a law on local governance known as the ''Baladie'' ([[municipal law]]), providing a detailed outline of issues such as the role of councils within the city, the members' qualifications, the election process, and the requirements to be entitled to vote.

As a result, the monarch was exiled and replaced by his son [[Ahmad Shah Qajar|Ahmad]], and the parliament was re-established.

During the Iran–Iraq War in 1980 to 1988, Tehran was repeatedly targeted by airstrikes and [[Scud missile]] attacks. The war led to substantial infrastructural damage, but the post-war period saw efforts to rebuild and modernize the city. The government initiated large-scale reconstruction projects, focusing on expanding urban infrastructure, including roads, bridges, and public buildings, to accommodate the growing population and to assert the Islamic Republic's presence in the capital. The revolution's leaders prioritized rebuilding and developing public spaces to accommodate the growing population and project a national identity centered around Islamic principles. In particular, the Ekbatan Complex, a major housing development project initiated during this period, became a symbol of the Islamic Republic's housing strategy. The complex was designed to provide affordable living for Tehran's expanding urban population and remains a notable example of the period's architectural ambitions.<ref>{{Cite journal |last=Sedighi |first=Mohamad |date=2018-04-12 |title=Megastructure Reloaded: A New Technocratic Approach to Housing Development in Ekbatan, Tehran |journal=ARENA Journal of Architectural Research |language=en-US |volume=3 |issue=1 |doi=10.5334/ajar.56 |doi-access=free |issn=2397-0820}}</ref><ref>{{Cite journal |last=Khatam |first=Azam |date=December 2015 |title=Tehran Urban Reforms Between Two Revolutions Developmentalism, Worlding Urbanism and Neoliberalism |url=https://core.ac.uk/reader/77106470 |journal=Graduate Program in Environmental Studies York University}}</ref>

There was a drastic change in ethnic-social composition in the early 1980s. After the political, social, and economic consequences of the 1979 Revolution and the years that followed, many Iranian citizens, mostly Tehranis, left Iran. The majority of [[Iranian diaspora|Iranian emigrations]] have left for the [[Iranian Americans|United States]], [[Iranians in Germany|Germany]], [[Swedish Iranians|Sweden]], and [[Iranian Canadians|Canada]]. With the start of the Iran–Iraq War, a second wave of inhabitants fled the city, especially during the Iraqi air offensives on Tehran. With most major powers backing Iraq at the time, economic isolation gave yet more reason for many inhabitants to leave Tehran and the country. Having left all they had and having struggled to adapt to a new country and build a life, most of them never came back when the war was over. During the war, Tehran received a great number of migrants from the west and the southwest of Iran bordering [[Iraq]]. The unstable situation and the war in neighbouring [[Afghanistan]] and Iraq prompted a rush of refugees into Iran, who arrived in millions. Tehran was a magnet for many seeking work, who helped Tehran to recover from war wounds, working for a far lower pay than local construction workers. Many of these refugees are being repatriated with the assistance of the [[United Nations High Commissioner for Refugees|UNHCR]], but there are still sizable groups of Afghan and Iraqi refugees in Tehran who are reluctant to leave, being pessimistic about the situation in their own countries. Afghan refugees are mostly [[Dari language|Dari]]-speaking [[Tajiks|Tajik]] and [[Hazara people|Hazara]], speaking a variety of Persian, and Iraqi refugees are mainly [[Mesopotamian Arabic]]-speakers who are often of Iranian and Persian ethnic heritage.

[[File:Tehran Profile, Level 1, 2012.jpg|thumb|A 2012 urban sustainability analysis of the metropolitan area of Tehran, using the 'Circles of Sustainability' method of the [[United Nations Global Compact|UN Global Compact]] Cities Programme]]
Most of Tehran has a cold [[semi-arid climate]], ''BSk'' within the [[Köppen climate classification]]. The climate is ''BSh'' (hot semi-arid) around [[Mehrabad International Airport]] and cold semi-arid in higher areas, with a borderline [[Mediterranean climate#Hot-summer Mediterranean climate|Mediterranean climate]] (''Csa'') in the northern area of Tehran, with hot, dry summers and cool, rainy winters.<!---PLEASE DO NOT CHANGE THIS TO 'COLD SEMI-ARID CLIMATE' BECAUSE THAT'S INCORRECT. TEHRAN'S AVERAGE ANNUAL TEMPERATURE OF 15.6 WHEN MULTIPLIED BY 20 GIVES A TOTAL OF 312, WHICH IS SIGNIFICANTLY LESS THAN THE TOTAL ANNUAL PRECIPITATION OF 429 MM.---> Tehran's climate is largely defined by its geographic location, with the towering [[Alborz]] mountains to its north and Iran's central desert to the south.


There are significant differences in elevation among various districts, and the weather is often cooler in the hilly north than in the flat southern part of Tehran. For instance, the {{cvt|17.3|km}} [[Valiasr Street]] runs from Tehran's railway station at {{cvt|1117|m}} elevation above sea level in Tehran's south, to [[Tajrish Square]] at 1712.6&nbsp;m (5612.3&nbsp;ft) elevation above sea level in the north.<ref>{{Cite web |url=https://www.freemaptools.com/elevation-finder.htm |title=Elevation Finder |last=Tools |first=Free Map |website=Freemaptools.com |language=en |access-date=2 February 2017 |archive-date=16 May 2020 |archive-url=https://web.archive.org/web/20200516040306/https://www.freemaptools.com/elevation-finder.htm |url-status=live }}</ref> The elevation rises up to {{cvt|2000|m}} at the end of [[Velenjak]] in northern Tehran. The sparse texture, the existence of old gardens, orchards, green spaces along the highways and the lack of industrial activities in the north of Tehran make the air in the northern areas 2 to 3 degrees Celsius cooler than the southern areas.<ref name="Tehran Geography">{{Cite web |url=https://www.cgie.org.ir/fa/article/27105/تهران--جغرافیا--شیوا-جعفری |title=Tehran Geography |language=fa |access-date=11 October 2018 |archive-date=11 September 2018 |archive-url=https://web.archive.org/web/20180911143144/https://www.cgie.org.ir/fa/article/27105/تهران--جغرافیا--شیوا-جعفری |url-status=live }}</ref> Air currents have a great effect on Tehran's weather.

Tehran lies at the southern foot of the [[Alborz Mountains]] and the northern edge of the [[Iranian Central Plateau]], giving the city a complex climate that combines mountainous influences, semi-arid plateau conditions, and localized [[micro-climate]]s. According to the [[Köppen climate classification system]], the bulk of metropolitan Tehran is classified as a [[semi-arid|cold semi-arid]] (BSk), while lower elevation suburbs and plains (near Mehrābād Airport) verge on a [[semi-arid|hot semi-arid]] (BSh) classification. At the same time, the elevated northern districts (such as [[Shemiran]]) approach a [[Mediterranean climate#Hot-summer Mediterranean climate|Mediterranean climate]] (''Csa'') type climate in some interpretations.
 
====Temperature====
 
Summers in Tehran are long and dry. Daytime highs often soar to over 35 °C, and during peak [[heat waves]] they may approach or even exceed 40 °C. Nighttime minima during midsummer typically hover around 20-25 °C, though cooler nights are common in the northern districts. Winters are relatively cool in central areas but are notably colder in the higher elevations north of the city: daytime highs in January average around 7-9 °C, while overnight lows in the city centre fall to near 0-2°C or slightly below and occasionally dip below zero in the suburbs and mountain-adjacent zones.<ref name="Tehran Geography">{{Cite web |url=https://www.cgie.org.ir/fa/article/27105/%D8%AA%D9%87%D8%B1%D8%A7%D9%86--%D8%AC%D8%BA%D8%B1%D8%A7%D9%81%DB%8C%D8%A7--%D8%B4%DB%8C%D9%88%D8%A7-%D8%AC%D8%B9%D9%81%D8%B1%DB%8C |title=Tehran Geography |language=fa |access-date=11 October 2018 |archive-date=11 September 2018 |archive-url=https://web.archive.org/web/20180911143144/https://www.cgie.org.ir/fa/article/27105/%D8%AA%D9%87%D8%B1%D8%A7%D9%86--%D8%AC%D8%BA%D8%B1%D8%A7%D9%81%DB%8C%D8%A7--%D8%B4%DB%8C%D9%88%D8%A7-%D8%AC%D8%B9%D9%81%D8%B1%DB%8C |url-status=live }}</ref>
 
====Precipitation====
 
Annual total rainfall for central Tehran averages roughly 230-300 mm. The wet season spans from late autumn through early spring (roughly November to May), while the summer months (June to September) are extremely dry and often see no measurable rainfall. Most precipitation falls from frontal systems moving in from the northwest and through the [[Alborz]] range, with occasional convective storms. Snowfall occurs almost every winter, though accumulation in central Tehran is usually brief, while the northern districts and Alborz foothills receive heavier and longer-lasting snow.<ref>{{Cite web |title=Institute for Iranian Contemporary Historical Studies |url=https://www.iichs.ir/p/history.aspx?id=2 |url-status=live |archive-url=https://web.archive.org/web/20151121001916/http://www.iichs.ir/p/history.aspx?id=2 |archive-date=21 November 2015 |access-date=11 June 2018 |language=fa}}</ref>
 
====Topographical Variation====
 
The city’s wide elevation range—from approximately 1,100 m above sea level in the southern plains to over 1,800 m in the northern suburbs—yields pronounced topographic micro-climates.<ref>{{Cite web |url=https://www.freemaptools.com/elevation-finder.htm |title=Elevation Finder |last=Tools |first=Free Map |website=Freemaptools.com |language=en |access-date=2 February 2017 |archive-date=16 May 2020 |archive-url=https://web.archive.org/web/20200516040306/https://www.freemaptools.com/elevation-finder.htm |url-status=live }}</ref> The elevation rises up to {{cvt|2000|m}} at the end of [[Velenjak]] in northern Tehran.  
Northern parts of Tehran tend to be cooler, receive slightly more precipitation (including more snow), and retain more greenery. In contrast, the more open, lower-lying southern sections of the city experience stronger daytime heating, less relief through breezes, and larger temperature differences between day and night. Indeed, the difference between daily maximum and minimum temperatures (known as [[diurnal range]]) can be modest (≈ 10-12 °C) in built-up urban zones but may exceed 15-20 °C in suburbs or peripheral areas during clear, dry nights.<ref name="Tehran Geography"/>
 
====Urban Effects====
 
Urban expansion, the “[[heat-island]]” effect, and reduced vegetation have contributed to modest upward shifts in mean temperatures, particularly during summer nights. Stormwater runoff, dust from surrounding arid terrain, and [[air-pollution]] interactions further complicate the city’s climate dynamics. The dominance of dry summers means that water management and green-space planning carry particular significance for Tehran’s long-term habitability.<ref>{{Cite journal |last=Labzovskii |first=Lev |date=2 August 2019 |title=Working towards confident spaceborne monitoring of carbon emissions from cities using Orbiting Carbon Observatory-2 |url=https://www.sciencedirect.com/science/article/abs/pii/S0034425719303785 |journal=Remote Sensing of Environment |volume=233 (2019) 11359 |article-number=111359 |doi=10.1016/j.rse.2019.111359 |bibcode=2019RSEnv.23311359L |access-date=27 January 2020 |archive-date=27 January 2020 |archive-url=https://web.archive.org/web/20200127042353/https://www.sciencedirect.com/science/article/abs/pii/S0034425719303785 |url-status=live |url-access=subscription }}</ref>
 
====Air Currents====
 
Air currents have a great effect on Tehran's weather. The prevailing wind blowing from the west causes the west of Tehran to always be exposed to fresh air. Although this wind brings smoke and pollution from the western industrial areas, its strong wind takes polluted air out of Tehran.<ref name="Tehran Geography" />

TehranTemplate:Efn is the capital and largest city of Iran.[1] It is also the capital of Tehran province and the administrative center for Tehran County and its Central District.[2] With a population of around 9 million in the city,[3][4][5] and 15 million in the metropolitan area,[6] Tehran is the most populous city in Iran and West Asia,[7] the second largest metropolitan area in the Middle East after Cairo, and the 24th-most-populous metropolitan area in the world. Greater Tehran includes several municipalities, including but not limited to Karaj, Eslamshahr, Shahriar, Qods, Malard, Golestan, Pakdasht, Qarchak, Nasimshahr, Parand, Pardis, Andisheh and Fardis.

In classical antiquity, part of the territory of present-day Tehran was controlled by Rhages/Rey/Ray).[8] Modern Ray was absorbed into the metropolitan area of Greater Tehran. Tehran was 1st chosen as the capital of Iran in 1786 by Agha Mohammad Khan of the Qajar dynasty, because of its proximity to Iran's territories in the Caucasus—which were contested in the Russo-Iranian Wars—and to avoid the vying factions of prior ruling Iranian dynasties; the capital of Iran had been moved several times throughout its long history, with Tehran becoming the 32nd. Under (1848-1896), Tehran witnessed Iran's first institute of higher learning, bank, railway line, and museum. Large-scale construction works began in the 1920s, and Tehran became a destination for mass migrations from all over Iran especially in the 20th century.[9]

Tehran is home to many historical sites, including the World Heritage Site Golestan Palace of the Qajar dynasty and the Masoudieh, Sa'dabad, Niavaran and Marmar palace complexes of both the Qajar and Pahlavi dynasties. Landmarks include the Azadi Tower, a memorial built in 1971 to mark the 2,500th anniversary of the Persian Empire; the Milad Tower, the world's sixth-tallest self-supporting tower, completed in 2007; and the Tabiat Bridge, completed in 2014.[10][11][12][13] Tehran is served by Imam Khomeini International Airport, alongside the domestic Mehrabad Airport, a central railway station, Tehran Metro, the Tehran Bus Rapid Transit system, trolleybuses, and a large network of highways.

Because air pollution and earthquakes, there have been plans to relocate the capital to another area, although none have been approved. A 2016 survey of 230 cities across the globe by Mercer ranked Tehran 203rd for quality of life.[14] According to the Global Destinations Cities Index in 2016, Tehran is among the top ten fastest growing tourism destinations.[15] In 2016, the Tehran City Council declared 6 October "Tehran Day", celebrating the date in 1907 when the city officially became the capital of Iran.[16]

Etymology

Various theories on the origin of the name Tehran have been put forward. Iranian linguist Ahmad Kasravi, in an article "Shemiran-Tehran", suggests that Tehran, and Kehran mean "the warm place", and "Shemiran" means "the cool place". He lists cities with the same base and suffix and studied the components of the word in ancient Iranian languages, and came to the conclusion that Tehran and Kehran meant the same thing in different Iranian language families, as the constant "t" and "k" are close to each other in such languages. He also provided evidence that cities named "Shemiran" were colder than those named "Tehran" or "Kehran". He considered other theories not consider the ancient history of Iranian languages, such as "Tirgan" theory and "Tahran" theory folk etymology.[17]

The official City of Tehran website says that "Tehran" comes from the Persian words "Tah" meaning "end", or "bottom", and "Ran" meaning "[mountain] slope"—, the bottom of the mountain (ته کوه), referring to Tehran's position at the foot of the Alborz mountains.[18]

The most interesting toponymic theory of the place name Tehran is proposed by the Iranian linguist Zana Vahidzadeh (Dana Pishdar). According to Dana Pishdar, the etymological root of the place name Tehran should be sought in the ancient Iranian languages, such as Median and Avestan. Since the city of Rey and the area around Tehran were the largest cities in the Media region in pre-Islamic times, and since in Zoroastrian times they were considered a holy city and the center of a theocratic government similar to modern Vatican City, this suggestion does not sound illogical.[19]

According to Dana Pishdar, the name Tehran consists of two lexical elements: "Teh" and "Ran." According to Pishdar, "Teh" in the ancient Median language means "honeyberry," and "Ran" means "foot of hills." Honeyberry trees used to grow in the northern parts of Tehran province. It is also mentioned in the Dehkhoda dictionary, where Dehkhoda explains it as follows: "Teh" is a noun used in Shemiranat and around Tehran for "the honeyberry tree."

According to Dana Pishdar (Zana Vahidzadeh), the word Tehran means a place where the "honeyberry tree" grows. The suffix "Ran" is also found in many names of districts and villages in modern Tehran, such as Shemiran, Niavaran, Jamaran, Kasran, and Shahran, which are also not unrelated to each other. In Avestan and also in the Avesta, "Ran" had the meaning of "foot" and "plain," which is still associated with the name of the city of Rey. The Zoroastrian Medes called their largest and most important city Rhaga or Rey, which means the city located on the plain and at a foot. Therefore, the words "Rey" and "Ran" mean the foot of the mountain, and the etymological reason for this is the geographical location of Rey and Tehran, because both are located at the foot of the mountain and on a plain.[20]

In English, it is also spelt "Teheran",[21] with both variants being used in books since at least 1800, and "Teheran" being the dominant form from after WWII until shortly before the Islamic Revolution.[22]

History

Template:For timeline

Archaeological remains from the ancient city of Ray suggest that settlement in Tehran dates back over 6,000 years.[23]

Classical era

Tehran is in the historical Media region of (Template:Langx Template:Transliteration) in northwestern Iran. By the time of the Median Empire, part of present-day Tehran was a suburb of the prominent Median city of Rhages (Template:Langx Template:Transliteration). In the Avesta's Videvdat (i, 15), Rhages is mentioned as the 12th sacred place created by Ohrmazd.[24] In Old Persian inscriptions, Rhages appears as a province (Bistun 2, 10–18). From Rhages, Darius I sent reinforcements to his father Hystaspes, who was putting down a rebellion in Parthia (Bistun 3, 1–10).[24] Some Middle Persian texts give Rhages as the birthplace of Zoroaster,[25] although modern historians generally place the birth of Zoroaster in Khorasan province.

Mount Damavand, the highest peak of Iran, which is located near Tehran, is an important location in Ferdowsi's Šāhnāme,[26] an Iranian epic poem based on the ancient legends of Iran. It appears in the epics as the homeland of the protoplast Keyumars, the birthplace of King Manuchehr, the place where King Fereydun bound the dragon fiend Aždahāk (Bivarasp), and the place where Arash shot his arrow.[26]

Medieval period

In 641, during the reign of the Sasanian Empire, Yazdgerd III issued his last appeal to the nation from Rhages, before fleeing to Khorasan.[24] Rhages was dominated by the Parthian House of Mihran, and Siyavakhsh—the son of Mehran, the son of Bahram Chobin—who resisted the seventh-century Muslim invasion of Iran.[24] Because of this resistance, when the Arabs captured Rhages, they ordered the town destroyed and rebuilt anew by traitor aristocrat Farrukhzad.[24]

In the ninth century, Tehran was a well-known village, but less so than Rhages, flourishing nearby. Rhages was described in detail by tenth-century Muslim geographers.[24] Despite the interest that Arabian Baghdad displayed in Rhages, the number of Arabs in the city remained insignificant and the population mainly consisted of Iranians of all classes.[24][27]

The Oghuz Turks invaded Rhages in 1035 and again in 1042, but the city was recovered under the Seljuks and the Khwarezmians.[24] Medieval writer Najm od Din Razi declared the population of Rhages about 500,000 before the Mongol invasion. In the 13th century, the Mongols invaded Rhages, laid the city to ruins, and massacred many of its inhabitants.[24] Others escaped to Tehran. In July 1404, Castilian ambassador Ruy González de Clavijo visited Tehran on a journey to Samarkand, the capital of Turco-Mongol conqueror Timur, the ruler of Iran at the time. He described it in his diary as an unwalled region.

Early modern era

Italian traveler Pietro della Valle passed through Tehran overnight in 1618, and in his memoirs called the city Taheran. English traveler Thomas Herbert entered Tehran in 1627, and mentioned it as Tyroan. Herbert states that the city had about 3,000 houses.[28]

In the early 18th century, Karim Khan of the Zand dynasty ordered a palace and a government office built in Tehran, possibly to declare the city his capital; but he later moved his government to Shiraz. Eventually, Qajar king Agha Mohammad Khan chose Tehran as the capital of Iran in 1786.[29] Khan's choice of his capital was based on a similar concern for the control of both northern and southern Iran.[29] He was aware of the loyalties of the inhabitants of former capitals Isfahan and Shiraz to the Safavid and Zand dynasties respectively, and was wary of the power of the local notables in these cities.[29] Thus, he probably viewed Tehran's lack of a substantial urban structure as a blessing, because it minimized the chances of resistance to his rule by the notables and by the general public.[29] He had to remain within close reach of Azerbaijan and Iran's integral northern and southern Caucasian territories[29]—at that time not yet irrevocably lost per the treaties of Golestan and Turkmenchay to the neighboring Russian Empire—which would follow in the course of the 19th century.[30]

After 50 years of Qajar rule, the city still barely had more than 80,000 inhabitants.[29] Up until the 1870s, Tehran consisted of a walled citadel, a roofed bazaar, and the three main neighborhoods of Udlajan, Chale-Meydan, and Sangelaj, where the majority resided.

During the long reign of Naser al-Din Shah (1848-1896), Tehran witnessed Iran's first institute of higher learning, bank, railway line and museum.[31][32][33] The Golestan Palace was significantly rebuilt and expanded in 1865 by Haji Ab ol Hasan Mimar Navai, including the Brilliant Hall, the Mirror Hall and the Edifice of the Sun. The city expanded rapidly through multiple development plans.[34] The first development plan in 1855 emphasized traditional spatial structure. The second, under the supervision of Dar ol Fonun in 1878, included new city walls, in the form of a perfect octagon with an area of 19 square kilometers, mimicking the Renaissance cities of Europe.[35] Tehran was 19.79 square kilometers and had expanded more than fourfold.[36]

Late modern era

File:Poster of Conquest of Tehran in July 1909 by Bakhtiaris.jpg
The Triumph of Tehran: Sardar Asad II and Sepahsalar e Tonekaboni conquering Tehran in July 1909

Growing awareness of civil rights resulted in the Constitutional Revolution and the first constitution of Iran in 1906. On 2 June 1907, the parliament passed a law on local governance known as the Baladie (municipal law), providing a detailed outline of issues such as the role of councils within the city, the members' qualifications, the election process, and the requirements to be entitled to vote.

Mohammad Ali Shah abolished the constitution and bombarded the parliament with the help of the Russian-controlled Cossack Brigade on 23 June 1908. That was followed by the capture of the city by the revolutionary forces of Ali-Qoli Khan (Sardar Asad II) and Mohammad Vali Khan (Sepahsalar e Tonekaboni) on 13 July 1909. As a result, the monarch was exiled and replaced by his son Ahmad, and the parliament was re-established.

During the Persian campaign of World War I, Russian forces that were occupying the northwest of Iran marched around Qazvin and approached Tehran, causing a crisis and the dissolution of parliament. Ahmad Shah Qajar and his entourage decided to leave Tehran and move the capital to another place, sparking fears of rebellion in other cities.[37] During the Battle of Robat Karim, Iranian forces led by Heydar Latifiyan prevented the Russians from taking Tehran, despite the latter winning the battle.[38] This also allowed government functions to be moved to Qom and then to Isfahan, while the monarchy remained in Tehran.[37]

Pahlavi rule

File:Toopkhooneh ghadeem.jpg
Under Reza Shah's reign, Tehran underwent a transformative modernization, with the establishment of urban infrastructure, modern streets, educational institutions, and public amenities, marking a pivotal step toward a structured, contemporary capital.[39]

After World War I, the constituent assembly elected Reza Shah of the Pahlavi dynasty as the new monarch, who immediately suspended the Baladie law of 1907, replacing the decentralized and autonomous city councils with centralist approaches to governance and planning.[35] From the 1920s to the 1930s, under the rule of Reza Shah, the city was rebuilt. Several old buildings, including parts of the Golestan Palace, Tekye Dowlat, and Tupkhane Square, were replaced with modern buildings influenced by classical Iranian architecture, particularly the buildings of the National Bank, the police headquarters, the telegraph office, and the military academy.

File:University of Tehran Students ceremony.jpg
The University of Tehran was founded in 1934, a landmark in Iran's modernization. Its establishment introduced advanced education, modern infrastructure, and public amenities, transforming Tehran into a vibrant, contemporary capital.

Changes to the urban fabric began with the street-widening act of 1933, which served as a framework for changes in all other cities. The Grand Bazaar was divided in half and many historic buildings were demolished and replaced by wide straight avenues,[40] and the traditional texture of the city was replaced with intersecting cruciform streets that created large roundabouts in major public spaces such as the bazaar. As an attempt to create a network for easy transportation within the city, the old citadel and city walls were demolished in 1937, replaced by wide streets cutting through the urban fabric. By 1937, the city was heavily influenced by modernist planning patterns of zoning and gridiron networks.[35]

During World War II, Soviet and British troops entered the city. In 1943, Tehran was the site of the Tehran Conference, attended by U.S. President Franklin D. Roosevelt, Soviet premier Joseph Stalin, and British Prime Minister Winston Churchill.

The establishment of the planning organization of Iran in 1948 resulted in the first socioeconomic development plan covering the period from 1949 to 1955. These plans not only failed to slow the unbalanced growth of Tehran but, with the 1962 land reforms that Reza Shah's son and successor, Mohammad Reza Shah named the White Revolution, Tehran's chaotic growth was further accentuated.

In the 1960s and 1970s, Tehran developed rapidly under Mohammad Reza Shah. Modern buildings altered the face of Tehran, and ambitious projects were planned for the following decades. To resolve the problem of social exclusion, the first comprehensive plan was approved in 1968. The consortium of Iranian architect Abd-ol-Aziz Farmanfarmaian and the American firm of Victor Gruen Associates identified the main problems blighting the city as high-density suburbs, air and water pollution, inefficient infrastructure, unemployment, and rural-urban migration. Eventually, the whole plan was marginalized by the 1979 Revolution and the subsequent Iran–Iraq War.[35]

Tehran's most famous landmark, the Azadi Tower, was built by the order of the Shah in 1971. It was designed by Hossein Amanat, an architect whose design won a competition, combining elements of classical Sassanian architecture with post-classical Iranian architecture. Formerly known as the Shahyad Tower, it was built to commemorate the 2,500th anniversary of the Imperial State of Iran.

Islamic Republic

File:1979 Iranian Revolution.jpg
Azadi Tower during the 1979 Islamic Revolution

Following the 1979 Islamic Revolution, Tehran underwent profound transformations in its urban landscape, political structure, and social dynamics. The revolution led to the establishment of the Islamic Republic of Iran, which brought about a shift from a pro-Western monarchy to a theocratic system based on Islamic principles. This change was reflected in various aspects of Tehran's development.[41][42][43] Politically, the revolution resulted in the consolidation of power by forces loyal to Ayatollah Ruhollah Khomeini, the leader of the revolution. This period saw the establishment of new governance structures aligned with Islamic ideologies.[44][45]

During the Iran–Iraq War from 1980 to 1988, Tehran was repeatedly targeted by airstrikes and Scud missile attacks, and the war led to substantial infrastructural damage.[46][47]

The 435-meter-high Milad Tower, one of the proposed development projects of pre-revolutionary Iran,[48] was completed in 2007 and has become a famous landmark of Tehran. Tabiat Bridge, a 270-meter pedestrian overpass[10] that was designed by award-winning architect Leila Araghian, was completed in 2014. The city municipality started planting a large number of imported palm trees, replacing endemic plane trees.[49] In June 2025, Tehran was attacked by Israeli airstrikes.[50] On June 2025 an unprecedented event in the history of Iran and Tehran took place as people of Tehran committed mass evacuation.[51][52][53]

Population

Template:Historical populations

Tehran had a population of 7,711,230 people, in 2,286,787 households at the time of the 2006 National Census.[54] The 2011 census counted 8,154,051 people, in 2,624,511 households.[55] The 2016 census recorded 8,693,706 people, in 2,911,065 households.[56]

Language and ethnicity

With its cosmopolitan atmosphere, Tehran is home to diverse ethnic and linguistic groups from all over the country, with the majority being the Caspians.

Iranian Azerbaijani Turks are the second-largest ethnic group, comprising about 10-15% [57][58] of the population. Tehran's other ethnic communities include Kurds, Armenians, Georgians, Bakhtyaris, Talysh, Baloch, Assyrians, Arabs, Jews, and Circassians. In the 2010 census by the Sociology Department of the University of Tehran, in many districts of Tehran across various socio-economic classes in proportion to population sizes of each district and socio-economic class, 63% of the people were born in Tehran, 98% knew Persian, 75% identified themselves as Tehrani, and 13% had some degree of proficiency in a European language.[59]

There was a drastic change in ethnic-social composition in the early 1980s. After the political, social, and economic consequences of the 1979 Revolution and the years that followed, many Iranian citizens, mostly Tehranis, left Iran. The majority of Iranian emigrations have left for the United States, Germany, Sweden, and Canada. With the start of the Iran–Iraq War, a second wave of inhabitants fled the city, especially during the Iraqi air offensives on Tehran. With most major powers backing Iraq at the time, economic isolation gave yet more reason for many inhabitants to leave Tehran and the country. Having left all they had and having struggled to adapt to a new country and build a life, most of them never came back when the war was over. During the war, Tehran received a great number of migrants from the west and the southwest of Iran bordering Iraq.

Religion

Script error: No such module "Labelled list hatnote". The majority of religious Tehrani are officially Twelver Shia Muslims, which has been the main religion since the 16th-century Safavid conversion. Other religious communities include followers of the Sunni and Mystic branches of Islam, Christian denominations, Judaism, Zoroastrianism, and the Baháʼí Faith. As of October 2025, because of government restrictions, finding a recent survey is difficult.

There are many religious centres scattered around Tehran, from old to newly built centres, including mosques, churches, synagogues, and Zoroastrian fire temples. Tehran has a very small third-generation Indian Sikh community with a local gurdwara that was visited by the Indian Prime Minister, Manmohan Singh in 2012.[60]

Geography

Script error: No such module "Labelled list hatnote".

Location and subdivisions

File:Tehran district map (blank).svg
The districts of Tehran

City of Tehran is bounded in the north by southern end and the highest point of Alborz Mountain Range (Tochal Peak, 3'964m), in the east by a hilly stretch of Alborz (namely, Sorkheh Hesar National Park, part of Khojir National Park and the northeastern badlands), in the southeast by Raga Mountain and in the west and southwest by fertile meadows and many villages, fed by numerous rivers and streams, mainly Karaj and Jajrud.

The metropolis is divided into 22 municipal districts, each with its administrative center. Of the 22 municipal districts, 20 are located in Tehran County's Central District, while districts 1 and 20 are respectively located in the counties of Shemiranat and Ray.

Northern Tehran is the wealthiest part of the city,[61] with districts such as Zafaraniyeh, Jordan, Elahiyeh, Pasdaran, Kamranieh, Ajodanieh, Farmanieh, Darrous, Niavaran, Jamaran, Aghdasieh, Mahmoodieh, Velenjak, Qeytarieh, Ozgol and Ekhtiarieh.[62][63] The city center houses government ministries and headquarters. Commercial centers are located further north.

Topography

Northern Tehran is at the foot of Alborz, starting at an elevation of Template:Convert, with many houses and streets on steep slopes and hills. There is a stretch of hills in the middle of the city (which historically divided Tehran and Shemiran) with its highest point at Template:Convert. Southwards and westwards of those hills, Tehran is less steep. On the east, there are numerous hills, with the highest point at Template:Convert. The southern end of Tehran (Rey) is at Template:Convert, next to a single mountain (Raga) at Template:Convert.

Climate

File:Tehran Profile, Level 1, 2012.jpg
A 2012 urban sustainability analysis of the metropolitan area of Tehran, using the 'Circles of Sustainability' method of the UN Global Compact Cities Programme

Tehran lies at the southern foot of the Alborz Mountains and the northern edge of the Iranian Central Plateau, giving the city a complex climate that combines mountainous influences, semi-arid plateau conditions, and localized micro-climates. According to the Köppen climate classification system, the bulk of metropolitan Tehran is classified as a cold semi-arid (BSk), while lower elevation suburbs and plains (near Mehrābād Airport) verge on a hot semi-arid (BSh) classification. At the same time, the elevated northern districts (such as Shemiran) approach a Mediterranean climate (Csa) type climate in some interpretations.

Temperature

Summers in Tehran are long and dry. Daytime highs often soar to over 35 °C, and during peak heat waves they may approach or even exceed 40 °C. Nighttime minima during midsummer typically hover around 20-25 °C, though cooler nights are common in the northern districts. Winters are relatively cool in central areas but are notably colder in the higher elevations north of the city: daytime highs in January average around 7-9 °C, while overnight lows in the city centre fall to near 0-2°C or slightly below and occasionally dip below zero in the suburbs and mountain-adjacent zones.[64]

Precipitation

Annual total rainfall for central Tehran averages roughly 230-300 mm. The wet season spans from late autumn through early spring (roughly November to May), while the summer months (June to September) are extremely dry and often see no measurable rainfall. Most precipitation falls from frontal systems moving in from the northwest and through the Alborz range, with occasional convective storms. Snowfall occurs almost every winter, though accumulation in central Tehran is usually brief, while the northern districts and Alborz foothills receive heavier and longer-lasting snow.[65]

Topographical Variation

The city’s wide elevation range—from approximately 1,100 m above sea level in the southern plains to over 1,800 m in the northern suburbs—yields pronounced topographic micro-climates.[66] The elevation rises up to Template:Cvt at the end of Velenjak in northern Tehran. Northern parts of Tehran tend to be cooler, receive slightly more precipitation (including more snow), and retain more greenery. In contrast, the more open, lower-lying southern sections of the city experience stronger daytime heating, less relief through breezes, and larger temperature differences between day and night. Indeed, the difference between daily maximum and minimum temperatures (known as diurnal range) can be modest (≈ 10-12 °C) in built-up urban zones but may exceed 15-20 °C in suburbs or peripheral areas during clear, dry nights.[64]

Urban Effects

Urban expansion, the “heat-island” effect, and reduced vegetation have contributed to modest upward shifts in mean temperatures, particularly during summer nights. Stormwater runoff, dust from surrounding arid terrain, and air-pollution interactions further complicate the city’s climate dynamics. The dominance of dry summers means that water management and green-space planning carry particular significance for Tehran’s long-term habitability.[67]

Air Currents

Air currents have a great effect on Tehran's weather. The prevailing wind blowing from the west causes the west of Tehran to always be exposed to fresh air. Although this wind brings smoke and pollution from the western industrial areas, its strong wind takes polluted air out of Tehran.[64]

The main direction of the prevailing wind is northwest to southeast.[68] Other air currents that blow in the area are:

  1. Tochal breeze: With the rapid cooling of the Alborz mountain range at night, a local high-pressure center is formed on Mount Tochal. This cold current flows down the mountain because of its weight and high pressure. Thus, a gentle breeze blows into the city from the north at night.[64]
  2. Southern and southeastern regional winds: These winds blow from the desert plains in the hot months of the year.[64]
  3. Western winds: these winds are among the planetary winds that affect Tehran throughout the year and can be called the prevailing wind.[64]

Climate Data

The highest recorded temperature was Template:Cvt on 3 July 1958. The lowest recorded temperature was Template:Cvt on 8 January 1969.[69]Template:Weather box

Template:Weather box

Template:Weather box

In February 2005, heavy snow covered all parts of Tehran. Snow depth was recorded as Template:Cvt in the south and Template:Cvt in the north. One newspaper reported that it had been the worst weather in 34 years. Ten thousand bulldozers and 13,000 municipal workers were deployed to keep the main roads open.[70][71] On 5 and 6 January 2008, a wave of heavy snow and low temperatures covered Tehran in a thick layer of snow and ice, forcing the Council of Ministers to declare a state of emergency and close down the capital from 6 January to 7 January.[72] On 3 February 2014, Tehran received heavy snowfall, specifically in the northern parts of the city, with a depth of Template:Convert. In one week of successive snowfalls, roads were made impassable in some areas, with the temperature ranging from Template:Cvt  to  Template:Cvt.[73] On 3 June 2014, a severe thunderstorm with powerful microbursts created a haboob, engulfing Tehran in sand and dust and causing five deaths, with more than 57 injured. This event knocked down numerous trees and power lines. It struck between 5:00 and 6:00 p.m., dropping temperatures from Template:Cvt  to Template:Cvt  within an hour. The dramatic temperature drop was accompanied by wind gusts reaching nearly Template:Cvt.[74]

During July and August 2025, Tehran experienced extreme heat and severe drought conditions, marking one of the most acute environmental crises in the city’s recent history. Temperatures exceeded 40 °C during a prolonged heatwave, coinciding with the fifth consecutive year of below-average rainfall. Reservoir levels in the surrounding region fell, with water storage at Karaj Dam reduced by 58 percent, Lar by 34 percent, Taleghan by 32 percent, and the combined Latyan and Mamloo reservoirs by 47 percent compared to normal capacity. Inflows to major dams were reported to be 43 percent lower than the previous year.[75] The water shortage prompted authorities to announce temporary public holidays and the closure of government offices and banks to conserve electricity and water.[76][77][78] One of the most intense rainfalls in Tehran happened on 21 April 1962, with 10 hours of rain. Meteorology determined that the amount of rainfall on that one day was equivalent to six years.[79]

Environmental issues

File:Air pollution of Tehran - 5 January 2013 06.jpg
Heavy air pollution in Tehran

Tehran is located near two major fault lines. Tehran suffers from severe air pollution, 80% of it due to cars.[80] The remaining 20% is due to industrial pollution. Other estimates suggest that motorcycles account for 30% of air and 50% of noise pollution in Tehran.[81] Tehran is considered one of the strongest sources of greenhouse gas emissions in the Middle East. Enhanced concentration of carbon dioxide over Tehran, that likely originate from the anthropogenic urban sources in the city, is easily detectable from satellite observations throughout the year.[82] A plan to move the capital has been discussed many times in prior years, due mainly to the environmental issues of the region. In 2010, the government announced that "for security and administrative reasons, the plan to move the capital from Tehran has been finalized."[83] There are plans to relocate 163 state firms and several universities from Tehran to avoid damages from a potential earthquake.[83][84]

City officials are engaged in a battle to reduce air pollution. They have, for instance, encouraged taxis and buses to convert from petrol engines to compressed natural gas. The government has set up a "Traffic Zone" covering the city centre during peak traffic hours. Entering and driving inside this zone is only allowed with a special permit. There are efforts to raise people's awareness of the hazards of pollution. Pollution Indicator Boards have been installed all around the city to monitor the level of particulate matter (PM2.5/PM10), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), and carbon monoxide (CO).

Economy

Tehran Stock Exchange

Tehran is the economic centre of Iran.[85] About 30% of Iran's public-sector workforce and 45% of its large industrial firms are located in the city, and almost half of these workers are employed by the government.[86] Most of the remainder of workers are factory workers, shopkeepers, laborers, and transport workers.

Few foreign companies operate in Tehran, because of the government's complex international relations. But before the 1979 Revolution, many foreign companies were active in Iran.[87] Tehran's present-day modern industries include the manufacturing of automobiles, electronics and electrical equipment, weaponry, textiles, sugar, cement, and chemical products. It is also a leading centre for the sale of carpets and furniture. The oil refining companies of Pars Oil, Speedy, and Behran are based in Tehran.

Tehran relies heavily on private cars, buses, motorcycles, and taxis, and is one of the most car-dependent cities in the world. The Tehran Stock Exchange, is a full member of the World Federation of Exchanges and a founding member of the Federation of Euro-Asian Stock Exchanges.[88]

Fashion industry

Design, manufacturing, distribution, marketing, retail, advertising, and other sectors of the fashion industry in Tehran have been able to grow significantly according to the needs of the country. In particular, a large number of male and female models are working in Tehran's fashion advertising and promotion sections. Despite the lack of adequate laws to support models, payments to female models have been considered high. Also, modeling of children is usually prohibited in Tehran. Clothing manufacturers are closely related to other fashion sectors in Tehran. For example, the manufacturers of women's boots and bodysuits have strengthened their exports and branding in other countries by using this connection.[89]

Shopping

Script error: No such module "Labelled list hatnote". Tehran has a wide range of shopping centers and is home to over 60 modern shopping malls.[90][91] The city has a number of commercial districts, including those located at Valiasr, Davudie, and Zaferanie. The largest old bazaars are the Grand Bazaar and the Bazaar of Tajrish. Iran Mall is the largest mall in the world in area.[92] Most of the international branded stores and upper-class shops are in the northern and western parts of the city. Tehran's retail business is growing with several newly built malls and shopping centres.[90] Shoe (Mostly women's boots) manufacturing companies in Tehran can be reached in the malls.[93]

Tehran, as one of the main tourist destinations in Iran, has a wealth of cultural attractions. It is home to royal complexes of Golestan, Saadabad, and Niavaran, which were built under the reign of the country's last two monarchies. There are several historic, artistic, and scientific museums in Tehran, including:

The Museum of Contemporary Art hosts works of famous artists such as Van Gogh, Pablo Picasso, and Andy Warhol. The Iranian Imperial Crown Jewels, one of the largest jewel collections in the world, are on display at Tehran's National Jewelry Museum. Several cultural and trade exhibitions take place in Tehran, which are mainly operated by the country's International Exhibitions Company. The annual International Book Fair is known to the international publishing world as one of the most important publishing events in Asia.[94]

Following the Islamic Revolution in 1979, the political system changed from constitutional monarchy to Islamic republic. Then the construction of political power in the country needed to change so that new spectrums of political power and decision-making centers emerged in Iran. Motives, desires, and actions of these new political power decision-making centers in Iran made them rename streets and public places throughout the country, especially Tehran. For example Shahyad square changed to Azadi square and Pahlavi street changed to Valiasr street.[95] The metropolis of Tehran is equipped with a large network of highways and interchanges.

According to the head of Tehran Municipality's Environment and Sustainable Development Office, Tehran was designed to have a capacity of about 300,000 cars, but more than five million cars are on the roads.[96] The automotive industry has recently developed, but international sanctions influence the production processes periodically.[97] According to local media, Tehran has more than 200,000 taxis plying the roads daily,[98] with several types of taxi available in the city. Airport taxis have a higher cost per kilometer as opposed to regular green and yellow taxis in the city.

Buses

Tehran's bus rapid transit

Buses have served the city since the 1920s. Tehran's transport system includes conventional buses, trolleybuses, and bus rapid transit (BRT). The city's four major bus stations include the South Terminal, the East Terminal, the West Terminal, and the northcentral Beyhaghi Terminal.

The trolleybus system was opened in 1992, using a fleet of 65 articulated trolleybuses built by Czech Republic's Škoda.[99] This was the first trolleybus system in Iran.[99] In 2005, trolleybuses were operating on five routes, all starting at Imam Hossein Square.[100] Two routes running northeastwards operated almost entirely in a segregated busway located in the middle of the wide carriageway along Damavand Street, stopping only at purpose-built stops located about every 500 metres along the routes, effectively making these routes trolleybus-BRT (but they were not called such). The other three trolleybus routes ran south and operated in mixed traffic. Both route sections were served by limited-stop services and local (making all stops) services.[100] A 3.2-kilometer extension from Shoosh Square to Rah Ahan Square was opened in March 2010.[101] Visitors in 2014 found that the trolleybus system had closed, apparently sometime in 2013.[102] However, it reopened in March 2016, operating on a single 1.8-km route between Meydan-e-Khorasan (Khorasan Square) and Bozorgrah-e-Be'sat.[103][104] Around 30 vehicles had been refurbished and returned to service.[103][104] Extensions were planned.[104]

Tehran's bus rapid transit (BRT) was officially inaugurated in 2008. It has 10 lines with some 215 stations in different areas of the city. Template:As of, the BRT system had a network of Template:Convert, transporting 1.8 million passengers on a daily basis.

Parks and green spaces

Script error: No such module "Labelled list hatnote". There are over 2,100 parks within the metropolis of Tehran,[116] with one of the oldest being Jamshidie Park, which was first established as a private garden for Qajar prince Jamshid Davallu, and was then dedicated to the last empress of Iran, Farah Pahlavi. The total green space within Tehran stretches over 12,600 hectares, covering over 20 percent of the city's area. The Parks and Green Spaces Organization of Tehran was established in 1960, and is responsible for the protection of the urban nature present in the city.[117]

Tehran's Birds Garden is the largest bird park in Iran. There is also a zoo located on the Tehran–Karaj Expressway, housing over 290 species within an area of about five hectares.[118] In 2009, the Ab-o-Atash Park ("Water and Fire park") was founded. Its main features are an open water fountain area for cooling in the hot climate, fire towers, and an amphitheatre.[119]

Energy

Script error: No such module "Labelled list hatnote".Template:Pie chartGreater Tehran is supplied by surface water from the Lar dam on the Lar River in the northeast of the city, the Latyan dam on the Jajrood River in the north, the Karaj River in the northwest, as well as by groundwater in the vicinity of the city. The city experiences stark water supply inequalities: impoverished districts struggle with inadequate water provision and hazardous water quality, while affluent areas are largely exempt from these hardships.[120]

According to the national energy roadmap, the government plans to promote green technology to increase the nominal capacity of power plants from 74 gigawatts to over 120 gigawatts by the end of 2025.[121] Solar panels have been installed in Pardisan Park for green electricity production, said Masoumeh Ebtekar, head of the Department of Environment.

The University of Tehran is the oldest modern university of Iran

Tehran is the largest and most important educational center in Iran. There are a total of nearly 50 major colleges and universities in Greater Tehran. Since the establishment of Dar ol Fonun by the order of Amir Kabir in the mid-19th century, Tehran has amassed a large number of institutions of higher education. Some of these institutions have played crucial roles in the unfolding of Iranian political events. Samuel M. Jordan, whom Jordan Avenue in Tehran was named after, was one of the founding pioneers of the American College of Tehran, which was one of the first modern high schools in the Middle East. Tehran is home to Iran's largest military academy and several religious schools and seminaries.

Among major educational institutions located in Tehran, Amirkabir University of Technology (Tehran Polytechnic), University of Tehran, Sharif University of Technology, and Tehran University of Medical Sciences are the most prestigious. Other major universities located in Tehran include Tehran University of Art, Allameh Tabatabaei University, K. N. Toosi University of Technology, Shahid Beheshti University (Melli University), Kharazmi University, Iran University of Medical Sciences, Islamic Azad University, International Institute of Earthquake Engineering and Seismology, Iran's Polymer and Petrochemical Institute, Shahed University, and Tarbiat Modarres University. Sharif University of Technology, Amirkabir University of Technology, Iran University of Science and Technology and K. N. Toosi University of Technology also located in Tehran is nationally well known for taking in the top undergraduate Engineering and Science students; and internationally recognized for training competent undergraduate students. It has probably the highest percentage of graduates who seek higher education abroad.

Culture

Script error: No such module "Labelled list hatnote".

Iranian festivals are held in Tehran along with regional and western festivals. Nowruz, Chaharshanbe Suri, Sizdah Be-dar, Yaldā Night, Valentine's Day and Halloween have been popular festivals in recent decades.[122]

Architecture

Script error: No such module "Labelled list hatnote". The oldest surviving architectural monuments are from the Qajar and Pahlavi eras. In Greater Tehran, monuments dating back to the Seljuk era remain as well; notably the Toqrol Tower in Ray. Rashkan Castle, dating back to the ancient Parthian Empire, of which some artifacts are housed at the National Museum;[123] and the Bahram fire temple, which remains since the Sassanian Empire. Tehran only had a small population until the late 18th century but it began to take a more considerable role in Iranian society after it was chosen as the capital city. Despite the regular occurrence of earthquakes during the Qajar period and after, some historic buildings remain from that era.[124] Tehran is Iran's primate city, and is considered to have the most modernized infrastructure in the country. However, the gentrification of old neighbourhoods and the demolition of buildings of cultural significance have caused concerns.[125]

Tehran was previously a low-rise city because of seismic activity in the region, but modern high-rise developments have been built in recent decades to service its growing population. There have been no major quakes in Tehran since 1830.[126] Tehran International Tower is the tallest skyscraper in Iran. It is 54-stories tall and located in the northern district of Yusef Abad. The Azadi Tower, a memorial built under the reign of the Pahlavi dynasty, has long been the most famous symbol of Tehran. Originally constructed in commemoration of the 2,500th year of the foundation of the Imperial State of Iran, it combines elements of the architecture of the Achaemenid and Sassanid eras with post-classical Iranian architecture. The Milad Tower, which is the sixth tallest tower[127] and the 24th-tallest freestanding structure in the world,[128] is the city's other famous landmark tower. Leila Araghian's Tabiat Bridge, the largest pedestrian overpass in Tehran, was completed in 2014 and is also considered a landmark.[10]

Fashion and clothing

Script error: No such module "Labelled list hatnote". The city has produced many notable Iranian design houses and clothing companies. Fashion events are also held in some areas of the city.[129] Many famous Iranian models were born in Tehran, including Nazanin Afshin-Jam, Cameron Alborzian, Sahar Biniaz, Elnaaz Norouzi, Shermine Shahrivar and Sadaf Taherian. Women of Tehran widely used over-the-knee and leather boots after 2000s.[130]

Theater

(Vahdat)
The roodaki Hall, Tehran

Under the reign of the Qajars, Tehran was home to the royal theatre of Tekye Dowlat, located to the southeast of the Golestan Palace, in which traditional and religious performances were observed. It was eventually demolished and replaced with a bank building in 1947, following the reforms during the reign of Reza Shah.

Before the 1979 Revolution, the Iranian national stage had become the most famous performing scene for known international artists and troupes in the Middle East,[131] with the Vahdat Hall, formerly but very much still known as Roodaki Hall (spelled in multiple ways in english), constructed to function as the national stage for opera and ballet. The hall was inaugurated in October 1967 and named after prominent Persian poet Rudaki. It is home to the Tehran Symphony Orchestra, the Tehran Opera Orchestra, and the Iranian National Ballet Company.

The City Theater of Tehran, one of Iran's biggest theatre complexes, which contains several performance halls, was opened in 1972. It was built at the initiative and presidency of Empress Farah Pahlavi, and was designed by architect Ali Sardar Afkhami, constructed within five years.

One of the gathering centers of cabarets in old Tehran was Laleh-Zar Street. Famous Persian cabarets were active in the city until 1979. They also introduced many domestic artists. In common language, cabaret was sometimes called "home of dance" or "dancing place".[132]

The annual events of Fajr Theater Festival and Tehran Puppet Theater Festival take place in Tehran.

Cinema

The first movie theater in Tehran was established by Mirza Ebrahim Khan in 1904.[133] Until the early 1930s, there were 15 theaters in Tehran province and 11 in other provinces.[134] Most of the movie theatres are located downtown. The complexes of Kourosh Cinema, Mellat Gallery and Cineplex, Azadi Cinema, and Cinema Farhang are among the most popular cinema complexes in Tehran. Several film festivals are held in Tehran, including Fajr Film Festival, Children and Youth Film Festival, House of Cinema Festival, Mobile Film and Photo Festival, Nahal Festival, Roshd Film Festival, Tehran Animation Festival, Tehran Short Film Festival, and Urban Film Festival.

Music and dance

There are a variety of concert halls in Tehran. An organization like the Roudaki Culture and Art Foundation has five different venues where more than 500 concerts take place this year. Vahdat Hall, Roudaki Hall, Ferdowsi Hall, Hafez Hall and Azadi Theater are the top five venues in Tehran, where classical, pop, traditional, rock or solo concerts take place.[135] Erotic dancers were active and trained in Tehran until the 1979 revolution. But after this date, because of the policies of the new government, these activities were completely banned.[122]

Sports

Script error: No such module "Labelled list hatnote". Football and volleyball are the city's most popular sports, while wrestling, basketball, and futsal are also major parts of the city's sporting culture. Ice hockey and rugby are also popular. 12 ski resorts operate in Iran, the most famous being Tochal, Dizin, and Shemshak, all within one to three hours from the city of Tehran.

Tochal's resort is the world's fifth-highest ski resort at over Template:Convert above sea level at its highest point. It is also the world's nearest ski resort to a capital city. The resort was opened in 1976, shortly before the 1979 Revolution. It is equipped with an Template:Convert gondola lift that covers a huge vertical distance.[136] There are two parallel chair ski lifts in Tochal that reach Template:Convert high near Tochal's peak, rising higher than the gondola's seventh station, which is higher than any of the European ski resorts. From the Tochal peak, there are views of the Alborz range, including the Template:Convert Mount Damavand, a dormant volcano.

Tehran is the site of the national stadium of Azadi, the biggest stadium by capacity in West Asia, where many of the top matches of Iran's Premier League are held. The stadium is a part of the Azadi Sport Complex, which was originally built to host the 7th Asian Games in September 1974. This was the first time the Asian Games were hosted in West Asia. Tehran played host to 3,010 athletes from 25 countries/NOCs, which was at the time the highest number of participants since the inception of the Games.[137] That followed hosting the 6th AFC Asian Cup in June 1976, and then the first West Asian Games in November 1997. The success of the games led to the creation of the West Asian Games Federation (WAGF), and the intention of hosting the games every two years.[138] The city had also hosted the final of the 1968 AFC Asian Cup. Several FIVB Volleyball World League courses have also been hosted in Tehran. In 2014, the city hosted the FILA Wrestling World Cup event at the Azadi Indoor Stadium.[139]

Food

Script error: No such module "Labelled list hatnote". There are many restaurants and cafes in Tehran, both modern and classic, serving both Iranian and cosmopolitan cuisine. Pizzerias, sandwich bars, and kebab shops make up the majority of food shops in Tehran.[140]

Graffiti

Script error: No such module "Labelled list hatnote".

Many styles of graffiti are seen in Tehran. Some are political and revolutionary slogans painted by governmental organizations,[141] and some are works of art by ordinary citizens, representing their views on both social and political issues. However, unsanctioned street art is forbidden in Iran,[141] and such works are usually short-lived. During the 2009 Iranian presidential election protests, many graffiti works were created by people supporting the Green Movement. They were removed from the walls by the paramilitary Basij forces.[142] In recent years, the Tehran Municipality has been using graffiti in order to beautify the city. Several graffiti festivals have also taken place in Tehran, including the one organized by the Tehran University of Art in October 2014.[143]
