{{Main|List of tallest structures}}

This is the '''history of the world's tallest structures'''.

==Overall==
Below is a list of the tallest structures supported by land.  For most of the period from around 2650 BC to 1240 AD, the [[Egyptian pyramids]] (culminating in the [[Great Pyramid of Giza]]) were the tallest structures in the world.  From 1240-1884 the records were held by European churches, and from 1954-2008 they were held by [[Guyed mast|guyed radio or TV masts]].

Since 2008, the [[Burj Khalifa]] in [[Dubai]] has been the tallest structure supported by land, at 829.8 metres (2,722 feet). There are [[oil platform]]s supported by the sea which have been of greater length since [[Oil platform#History of deepest offshore oil wells|about 1980]], with [[Oil platform#Particularly large examples|some examples]] up to 2,934 metres (9,627 feet).  In addition, some countries monitor their borders with [[Tethered balloon|tethered aerostats]] which can rise to 6,096 metres (20,000 feet).<ref>{{Cite web|url=https://www.mwrf.com/news/news/55280920/microwaves-rf-aerostat-systems-help-boost-border-security|title=Aerostat Systems Help Boost Border Security|first=Jack|last=Browne|date=April 9, 2025}}</ref>

[[Image:Maszt radiowy w Konstantynowie.jpg|thumb|upright|[[Warsaw radio mast]], the height record holder from 1974 to 1991]]

The [[Kanishka Stupa]] near [[Peshawar]], [[Pakistan]] was built c. 151 and rebuilt in the 4th century.  Ancient travelers claimed it was up to 171 metres (560 feet) tall, which would have been a record at the time.  Modern estimates suggest a height of 122 metres (400 feet), which would not have been a record.  It was destroyed by lightning.<ref>{{cite book|last1=Le|first1=Huu Phuoc|title=Buddhist Architecture|date=2010|publisher=Grafikol|isbn=9780984404308|url=https://books.google.com/books?id=9jb364g4BvoC&dq=hephthalite+peshawar&pg=PA51|access-date=24 March 2017}}</ref>

==Guyed structures==
As many large [[guyed mast]]s were destroyed at the end of World War II, the dates for the years between 1945 and 1950 may be incorrect. If [[Wusung Radio Tower]] survived World War II, it was the tallest guyed structure shortly after World War II.

==Freestanding structures==
{{See also|Skyscraper#History of the tallest skyscrapers}}
Freestanding structures must not be supported by guy wires (like [[guyed mast]]s or partially guyed towers), or built underground or on the [[seabed]] and supported by the sea (such as the [[Petronius Platform]]). They include towers, chimneys, and skyscrapers (listed based on their pinnacle height). Until 1954, freestanding structures held the record for tallest structures overall, as seen in the Overall table above.  Here are the records for freestanding structures after that point:

Notable mentions include the [[Lighthouse of Alexandria|Pharos (lighthouse) of Alexandria]], built in the third century BC and estimated between {{convert|115|–|135|m|ft|abbr=on}}. It was the world's tallest non-pyramidal structure for many centuries. Another notable mention includes the [[Jetavanaramaya]] [[stupa]] in [[Anuradhapura]], Sri Lanka, which was built in the third century, and was similarly tall at {{convert|122|m|ft|abbr=on}}. These were both the world's tallest or second-tallest non-pyramidal structure for over a thousand years.

The tallest ''secular'' building between the collapse of the Pharos and the erection of the [[Washington Monument]] may have been the [[Torre del Mangia]] in [[Siena]], Italy, which is {{convert|102|m|ft|abbr=on}} tall, and was constructed in the first half of the fourteenth century; and the {{convert|97|m|ft|adj=mid|-tall}} [[Torre degli Asinelli]] in [[Bologna]], Italy, built between 1109 and 1119.

==Freestanding towers==
[[File:TaroTokyo20110213-TokyoTower-01.jpg|right|thumb|[[Tokyo Tower]] held the record of being the tallest tower in the world from 1958 to 1967.

Towers include observation towers, monuments and other structures not generally considered to be "habitable buildings", they are meant for "regular access by humans, but not for living in or office work", meaning it excludes from this list of continuously habitable buildings and skyscrapers.

== Buildings ==
{{Main|List of tallest buildings}}

The [[Council on Tall Buildings and Urban Habitat]], an organization that certifies buildings as the "World's Tallest", recognizes a building only if at least 50% of its height is made up of floor plates containing habitable floor area.<ref name="ctbuh criteria">{{cite web |title=CTBUH Height Criteria for Measuring & Defining Tall Buildings |url=https://cloud.ctbuh.org/CTBUH_HeightCriteria.pdf |page=5 |publisher=[[Council on Tall Buildings and Urban Habitat]] |access-date=November 9, 2024 |archive-url=https://web.archive.org/web/20241109162341/https://cloud.ctbuh.org/CTBUH_HeightCriteria.pdf |archive-date=November 9, 2024 |url-status=live}}</ref> Structures that do not meet this criterion, such as the [[CN Tower]], are defined as "[[tower]]s".

Up until the late 1990s, the definition of "tallest building" was not altogether clear. It was generally understood to be the height of the building to the top of its architectural elements including spires, but not including "temporary" structures (such as antennas or flagpoles), which could be added or changed relatively easily without requiring major changes to the building's design. Varying standards have been used by different organizations, so the accepted height of these structures or buildings depends on which standards are accepted. The Council on Tall Buildings and Urban Habitat has changed its definitions over time. Some of the controversy regarding the definitions and assessment of tall structures and buildings has included the following:
* the definition of a structure, a building and a tower 
* whether a structure, building or tower under construction should be included in any assessment
* whether a structure, building or tower has to be officially opened before it is assessed
* whether structures built in and rising above water should have their below-water height included in any assessment.
* whether a structure, building or tower that is guyed is assessed in the same category as self-supporting structures.

Within an accepted definition of a building further controversy has included the following factors:
* whether only habitable height of the building is considered
* whether communication towers with [[Observation gallery|observation galleries]] should be considered "habitable" in this sense
* whether rooftop [[antenna (electronics)|antennas]], viewing platforms or any other architecture that does not form a habitable floor should be included in the assessment
* whether a floor built at a high level of a telecommunications or viewing tower should change the tower's definition to that of a "building"

One historic case involved the building now famous for the [[Times Square Ball]]. Known as [[One Times Square]] (at 1475 [[Broadway (Manhattan)|Broadway]] in [[Midtown Manhattan]]), it was the headquarters for'' [[The New York Times]], ''which gave [[Times Square]] its name. Completed in 1905, it reached a height of {{convert|364|ft|m|abbr=off|sp=us}} to its roof, or {{convert|420|ft|m|abbr=off|sp=us}} including its rooftop flagpole, which the ''Times'' hoped would give it a record high status but because a flagpole is not an integral architectural part of a building, One Times Square was not generally considered to be taller than the {{convert|390|ft|m|adj=mid|-high|sp=us}} [[Park Row Building]] in [[Lower Manhattan]], which was therefore still [[List of tallest buildings in New York City#Timeline of tallest buildings|New York's tallest]].<ref name="ctbuh defs history">{{cite web|url=http://ctbuh.org/AboutCTBUH/History/MeasuringTall/tabid/1320/language/en-US/Default.aspx|title=History of Measuring Tall Buildings|access-date=May 3, 2012|archive-url=https://web.archive.org/web/20120410072709/http://www.ctbuh.org/AboutCTBUH/History/MeasuringTall/tabid/1320/language/en-US/Default.aspx|archive-date=April 10, 2012|url-status=dead}}</ref>

A bigger controversy was the rivalry between two New York City [[skyscrapers]] built in the [[Roaring Twenties]]—the [[Chrysler Building]] and [[40 Wall Street]]. The latter was {{convert|927|ft|m|abbr=off|sp=us}} tall, had a shorter pinnacle, and had a much higher top occupied floor (the second category in the 1996 criteria for tallest building).<ref name="ctbuh defs history"/> In contrast, the Chrysler Building employed a very long {{convert|125|ft|m|adj=on}} spire secretly assembled inside the building to claim the title of world's tallest building with a total height of {{convert|1048|ft|m}}, despite having a lower top occupied floor and a shorter height when both buildings' spires are not counted in their heights.<ref>{{Cite news|url=https://www.nytimes.com/1929/10/20/archives/denies-altering-plans-for-tallest-building-starrett-says-height-of.html|title=Denies Altering Plans for Tallest Building; Starrett Says Height of Bank of Manhattan Structure Was Not Increased to Beat Chrysler.|date=October 20, 1929|work=The New York Times|access-date=April 26, 2020|language=en-US|issn=0362-4331}}</ref> Although the [[architect of record|architects of record]] for 40 Wall were [[H. Craig Severance]] and [[Yasuo Matsui]], the firm of [[Shreve & Lamb]] (who also designed the [[Empire State Building]]) served as consulting architects. They wrote a newspaper article claiming that 40 Wall was actually the tallest, since it contained the world's highest usable floor. They pointed out that the observation deck of 40 Wall was nearly {{convert|100|ft|m}} higher than the top floor of the Chrysler, whose surpassing spire was strictly ornamental and essentially inaccessible.<ref>Binders, George (August 2006). 101 of the World's Tallest Buildings. p. 102.</ref> Despite the protest, the Chrysler Building was generally accepted as the tallest building in the world for almost a year, until it was surpassed by the [[Empire State Building]]'s {{convert|1250|ft|m|abbr=off|sp=us}} in 1931.

That was in turn surpassed by the {{convert|1368|ft|m|adj=mid|-high|sp=us}} Twin Towers of New York's original [[World Trade Center (1973–2001)|World Trade Center]] in 1972, which were in turn surpassed by the Sears Tower in Chicago in 1974. Now called the [[Willis Tower]] since 2009, it was {{convert|1451|ft|m|abbr=off|sp=us}} to its flat rooftop, or {{convert|1518|ft|m|abbr=off|sp=us}} including its original antennas.<ref name="skyscraperpage.com">{{cite web |title=Willis Tower, Chicago – SkyscraperPage.com |url=http://skyscraperpage.com/cities/?buildingID=5/ |access-date=May 5, 2015 |website=SkyscraperPage.com}}</ref> But in 1978 One World Trade Center (commonly known as the North Tower) attained a taller absolute height when it added its {{convert|360|ft|m|adj=on}} new broadcasting antenna, for a total height of {{convert|1728|ft|m|1|abbr=off|sp=us}}. The WTC North Tower maintained this height record (including its antenna) from 1978 until 2000, when the owners of the Willis Tower extended its broadcasting antennae for a total height of {{convert|1729|ft|m|1|abbr=off|sp=us}}.<ref name="skyscraperpage.com"/> Thus the status of the Willis Tower as the "totally" tallest was restored in the face of a new threat looming in the Far East—the "[[Petronas Towers|Siamese Twins]]".

[[File:Petronas Twin Towers 2010 April.jpg|thumb|right|The Petronas Towers remain the tallest twin towers in the world.]]

A major controversy erupted upon completion of the [[Petronas Towers]] in [[Kuala Lumpur, Malaysia]] in 1998. These Twin Towers, at {{convert|1483|ft|m|abbr=off|sp=us}}, had a higher architectural height (spires, not antennas), but a lower absolute pinnacle height and a lower top occupied floor than the [[Willis Tower]] in Chicago. Counting buildings as structures with floors throughout, and with antenna masts excluded, the Willis was still considered the tallest at that time. Excluding their spires, which are {{convert|9|m|ft|abbr=off|sp=us}} higher than the flat roof of Willis, the Petronas Towers are not taller than Willis. At their convention in Chicago, the [[Council on Tall Buildings and Urban Habitat]] (CTBUH) found the Willis Tower (without its antennas) to be the third-tallest building, and the Petronas Towers (with their spires) to be the world's two tallest buildings.<ref name="ctbuh defs history"/>

Responding to the ensuing controversy, the CTBUH then revised their criteria and defined four categories in which the world's tallest building can be measured, retaining the old criterion of height to architectural top, and adding three new categories:<ref name="ctbuh defs history"/>

# Highest occupied floor
# Height to top of roof (omitted from criteria from November 2009 onwards)<ref name="ctbuh defs change">{{cite news|url=http://www.ctbuh.org/NewsMedia/PR_091117_ChangeHeightCriteria/tabid/1273/language/en-US/Default.aspx|title=CTBUH changes height criteria, Burj Khalifa height increases|date=November 17, 2009|publisher=[[Council on Tall Buildings and Urban Habitat]]|access-date=November 18, 2009|archive-url=https://web.archive.org/web/20180105123138/http://www.ctbuh.org/NewsMedia/PR_091117_ChangeHeightCriteria/tabid/1273/language/en-US/Default.aspx|archive-date=January 5, 2018|url-status=dead}}</ref>
# Height to architectural top (including [[spire]]s and pinnacles, but not antennas, masts or flagpoles). This measurement is the most widely used and is used to define the rankings of the 100 Tallest Buildings in the World.
# Height to tip

The height-to-roof criterion was discontinued because relatively few modern tall buildings possess flat rooftops, making this criterion difficult to determine and measure.<ref name="ctbuh defs change"/> The CTBUH has further clarified their definitions of building height, including specific criteria concerning subbasements and ground level entrances (height measured from lowest, significant, open-air, pedestrian entrance rather than from a previously undefined "main entrance"), building completion (must be topped out both structurally and architecturally, fully clad, ''and'' able to be occupied), condition of the highest occupied floor (must be continuously used by people living or working and be conditioned, thus including [[observation deck]]s, but not [[mechanical floor]]s) and other aspects of tall buildings.<ref name="ctbuh defs change"/><ref name="ctbuh current defs">{{cite web |title=CTBUH Height Criteria for Measuring & Defining Tall Buildings |url=https://cloud.ctbuh.org/CTBUH_HeightCriteria.pdf |pages=3–4 |publisher=[[Council on Tall Buildings and Urban Habitat]] |access-date=November 9, 2024 |archive-url=https://web.archive.org/web/20241109162341/https://cloud.ctbuh.org/CTBUH_HeightCriteria.pdf |archive-date=November 9, 2024 |url-status=live}}</ref>  The height is measured from the level of the lowest, significant, open-air, pedestrian entrance.

A different superlative for skyscrapers is their [[List of buildings with 100 floors or more|number of floors]]. The original World Trade Center set that record at 110 in the early 1970s, and this was not surpassed until the Burj Khalifa opened in 2010.

[[List of tallest freestanding structures|Tall freestanding structures]] such as the [[CN Tower]], the [[Ostankino Tower]] and the [[Oriental Pearl Tower]] are excluded from these categories because they are not "habitable buildings", which are defined as frame structures made with floors and walls throughout.<ref name="ctbuh criteria"/>
