[[File:KariyeCamii-Aussenansicht.jpg|thumb|Front]]

The '''Chora Church''' or '''Kariye Mosque''' ({{langx|tr|Kariye Camii}}) is a [[Byzantine architecture|Byzantine]] church, now converted to a [[mosque]] (for the second time), in the [[Edirnekapı, Istanbul|Edirnekapı]] neighborhood of [[Fatih]] district, [[Istanbul]], [[Turkey]]. It is famous for its outstanding Late [[Byzantine mosaic]]s and [[fresco]]s.

In the 16th century, during the [[Ottoman Empire|Ottoman]] era, it was converted into a mosque; it became a museum in 1945, and was turned back into a mosque in 2020 by President [[Recep Tayyip Erdoğan]].<ref name="Casper2020">{{cite web |last1=Casper |first1=Jayson |title=Turkey Turns Another Historic Church into a Mosque |url=https://www.christianitytoday.com/news/2020/august/turkey-chora-church-mosque-kariye-museum-hagia-sophia-istan.html |publisher=[[Christianity Today]] |access-date=22 August 2020 |language=en |date=21 August 2020}}</ref><ref>{{cite web|title= Turkey converts Kariye Museum into mosque |url= https://www.hurriyetdailynews.com/turkey-converts-kariye-museum-into-mosque-157585|publisher=[[Hürriyet Daily News]] |access-date=22 August 2020 |language=en |date=21 August 2020}}</ref> The interior is covered with some of the finest surviving Byzantine Christian [[mosaic]]s and [[fresco]]es, which were left in plain sight during Muslim worship throughout much of the Ottoman era.<ref>{{Cite web|url=https://www.theartnewspaper.com/news/has-turkey-halted-plans-to-turn-museum-into-a-mosque|title=Has Turkey halted plans to turn Chora museum into a mosque?|date=11 January 2021}}</ref> They were restored after the building was secularized and turned into a museum.

The church in the western [[Fatih]] district of İstanbul. It stands on sedimentary layers and anthropogenic infills
on a slope descending towards the north. It is oriented east-west, as are typical Byzantine churches throughout the city.

}}

===First phase (4th century)===
The Chora Church was originally built in the early 4th century as part of a monastery complex outside the [[Walls of Constantinople#Constantinian Walls|city walls]] of Constantinople erected by [[Constantine I (emperor)|Constantine the Great]], to the south of the [[Golden Horn]]. However, when [[Theodosius II]] built his formidable [[Walls of Constantinople#Theodosian Walls|land walls]] in 413–414, the church became incorporated within the city's defences, but retained the name Chora (for the presumed symbolism of the name see [[#Name|below]]).

===Second phase (11th century)===
The majority of the fabric of the current building dates from 1077–1081, when [[Maria of Bulgaria|Maria Doukaina]], the mother-in-law of [[Alexius I Comnenus]], rebuilt the Chora Church as an [[Cross-in-square|inscribed cross]] or ''quincunx'': a popular architectural style of the time. Early in the 12th century, the church suffered a partial collapse, perhaps due to an [[earthquake]].

===Third phase: new decoration (14th century)===
The church was rebuilt by [[Isaac Komnenos (son of Alexios I)|Isaac Comnenus]], Alexius's third son. However, it was only after the third phase of building, two centuries after, that the church as it stands today was completed. The powerful Byzantine statesman [[Theodore Metochites]] endowed the church with many of its fine [[mosaic]]s and [[fresco]]es. Theodore's impressive decoration of the interior was carried out between circa 1310 and 1317.<ref>K. Smyrlis, “Contextualizing [[Theodore Metochites]] and his refoundation of the Chora”, ''Revue des Etudes Byzantines'' 80 (2022), 69–111 doi: 10.2143/REB.80.0.3290897</ref> The mosaic work is the finest example of the [[Byzantine art#Palaeologan age|Palaeologian Renaissance]]. The artists remain unknown. A renowned classical scholar as well as statesman, Theodore donated his personal library to the Chora monastery, as well.<ref name=":0">{{Cite book |last=Freeman |first=Evan |url=https://pressbooks.pub/smarthistoryguidetobyzantineart/chapter/picturing-salvation-choras-brilliant-byzantine-mosaics-and-frescoes/ |title=A Smarthistory Guide to Byzantine Art |date=2021 |publisher=Smarthistory |chapter=Architecture in Focus: The Chora}}</ref> Later on, between 1315 and 1321, [[Theodore Metochites]], the Grand Logothete of the Treasury, commissioned the
construction of the funerary chapel, outer buttress supports, and the narthexes. In 1328, Theodore was sent into exile by the usurper [[Andronicus III Palaeologus]]. However, he was allowed to return to the city two years later, and lived out the last two years of his life as a [[monk]] in his Chora Church.

===Until the Conquest of Constantinople===
In the late 13th and early 14th centuries, the monastery was home to the scholar [[Maximus Planudes]], who was responsible for the restoration and reintroduction of [[Claudius Ptolemy|Ptolemy]]'s [[Ptolemy's Geography|''Geography'']] to the Byzantines and, ultimately, to [[Renaissance Italy]]. During the last [[Fall of Constantinople|siege of Constantinople]] in 1453, the [[Icon]] of the [[Theotokos]] [[Hodegetria]], considered the protector of the City, was brought to Chora in order to assist the defenders against the assault of the [[Ottoman Turks|Ottomans]].<ref>Van Millingen</ref>

===Kariye Mosque (c. 1500–1945)===
Around fifty years after the fall of the city to the [[Ottoman Empire|Ottomans]], [[Hadım Ali Pasha]], the [[Grand Vizier]] of Sultan [[Bayezid II]], ordered the Chora Church to be converted into a [[mosque]] — ''Kariye Camii''. The word Kariye derived from the Greek name Chora.<ref>{{cite web |title=About Chora |url=https://www.choramuseum.com |publisher=choramuseum}}</ref> The architectural modifications were kept minimal with minor whitewashing and the addition of a brick minaret and mihrab. None altered the spatial organisation of the church. Ottoman records indicate maintenance rather than renovation.<ref>(Eyice, Semavi. 2015. Eski İstanbul’dan Notlar. İstanbul: Türkiye İş Bankası Kültür Yayınları.)</ref> Due to the [[Aniconism in Islam|prohibition against iconic images]] in [[Islam]], the mosaics and frescoes were covered by a layer of plaster. This and frequent earthquakes in the region have taken their toll on the artwork. Additionally, the intervention efforts of the 19th century, led by Evkaf Nezareti, flattened the original domed roof profile, and masked the Late Byzantine silhouette.

===Museum, art restoration (1945–2020)===
In 1945 the site was secularized and designated a museum via Cabinet Decree, reflecting early Republican efforts to position Byzantine monuments as '''universal patrimony'''.<ref>T.C. Resmî Gazete. 1945. Kararname No: 5/1603, 29 August.</ref> In 1945, the building was designated a museum by the Turkish government.<ref name=Yackley>{{cite web |url=https://www.theartnewspaper.com/news/court-ruling-converting-turkish-museum-to-mosque-could-set-precedent-for-hagia-sophia |title=Court Ruling Converting Turkish Museum to Mosque Could Set Precedent for Hagia Sophia |last=Yackley |first=Ayla |date=3 December 2019 |publisher=The Art Newspaper |access-date=9 December 2019}}</ref> In 1948, the American scholars [[Thomas Whittemore]] and Paul A. Underwood, from the [[Byzantine Institute of America]] and the [[Dumbarton Oaks]] Center for Byzantine Studies, sponsored a restoration program. From that time on, the building ceased to be a functioning mosque. In 1958, it was opened to the public as a museum, ''Kariye Müzesi''.

===Reconversion to a mosque (2020–2024)===
In 2005, the Association of Permanent Foundations and Service to Historical Artifacts and Environment filed a lawsuit to challenge the status of the Chora Church as a museum.<ref>{{cite web |last1=Kokkinidis |first1=Tassos |title=Turkey to Turn Historic Orthodox Church Into a Mosque; Is Hagia Sophia Next? |date=21 November 2019 |url=https://eu.greekreporter.com/2019/11/21/turkey-to-turn-historic-orthodox-church-into-a-mosque-is-hagia-sophia-next/ |publisher=Greek Reporter |access-date=10 July 2020}}</ref> In November 2019, the [[Turkish Council of State]], Turkey's highest administrative court, ordered that it was to be reconverted to a mosque.<ref name=Yackley/> In August 2020, its status changed to a mosque.<ref>{{cite web |url=https://www.hurriyetdailynews.com/turkey-converts-kariye-museum-into-mosque-157585 |title=Turkey converts Kariye Museum into mosque |date=21 August 2020 |publisher= Hürriyet Daily News website |access-date=21 August 2020}}</ref>

The move to convert Chora Church into a mosque was condemned by the Greek Foreign Ministry and by Greek Orthodox and Protestant Christians.<ref name="Casper2020"/> This caused a sharp rebuke by Turkey.<ref>{{cite web|url=https://www.hurriyetdailynews.com/turkey-slams-greece-over-statement-on-conversion-of-kariye-museum-to-mosque-157599|title=Turkey slams Greece over statement on conversion of Kariye Museum to mosque|date=22 August 2020|publisher= Hürriyet Daily News website|access-date=24 August 2020}}</ref>

On Friday 30 October 2020, Muslim prayers were held for the first time after 72 years.<ref>{{Cite news|url=https://ahvalnews.com/chora-conversion/istanbuls-chora-open-mosque-muslim-prayers-oct-30|title=Istanbul's Chora to open as mosque for Muslim prayers on Oct. 30|newspaper=Ahval |date=27 October 2020 }}</ref>

==Legal Framework==

Kariye Mosque is situated within the “[[Historic Areas of Istanbul]]” inscribed on the [[UNESCO World Heritage List]] since 1985. falls under the protection of the 1972 UNESCO World Heritage Convention, where State Party reporting, conservation planning, and risk monitoring under the [[World Heritage Centre]] are mandated. The site is registered as a 1st degree archaeological and architectural heritage asset and is protected under [https://kvmgm.ktb.gov.tr/TR-43249/law-on-the-conservation-of-cultural-and-natural-property-2863.html Law No. 2863 on the Conservation of Cultural and Natural Properties]. 

The conversion to a museum in 1945, by the Cabinet Decree, was annulled. Regardless of the lawsuit opened by the Association of Permanent Foundations and Service to Historical Artifacts
and Environment in 2005, for its right to be museum, in 2019 by the Council of State ruling based on religious foundations. In 2020, the Presidential Decree transferred the rights to the Presidency of Religious Affairs. 

==Interior==
The Chora Church is not as large as some of the other surviving Byzantine churches of Istanbul (it covers 742.5 m²) but it is unique among them, because of its almost completely still extant internal decoration. The building is divided into three main areas: the entrance hall or ''[[narthex]]'', the main body of the church or ''[[nave|naos]]'' (nave), and the side [[chapel]] or ''[[parecclesion]]''. The building has six [[dome]]s: two above the ''esonarthex'', one above the ''parecclesion'' and three above the ''naos''.

===Narthex===
The main, west door of the Chora Church opens into the [[narthex]]. It divides north–south into the outer, or ''exonarthex'' and the inner, or ''esonarthex''.

====Exonarthex====
[[File:StPeter-mosaic-from-Chora-church-in-Istanbul.jpg|thumb|upright|Mosaic of [[Saint Peter]]]]

The exonarthex (or outer [[narthex]]) is the first part of the church that one enters. It is a transverse corridor, 4 m wide and 23 m long, which is partially open on its eastern length into the parallel esonarthex. The southern end of the exonarthex opens out through the esonarthex forming a western antechamber to the [[parecclesion]]. The mosaics that decorate the exonarthex include:

# Joseph's dream and the journey to [[Bethlehem]]
# The enrollment for taxation
# [[Nativity of Jesus|The Nativity]]
# The journey of the Magi
# The inquiry of King Herod;
# The [[flight into Egypt]]
# Two frescoes of the [[Massacre of the Innocents|massacres ordered by King Herod]]
# Mothers mourning their children
# The flight of [[Elizabeth (biblical figure)|Elizabeth]], mother of [[John the Baptist]]
# Joseph dreaming, and the return of the [[Holy Family]] from Egypt to [[Nazareth]]
# Christ taken to Jerusalem for the [[Passover]]
# John the Baptist bearing witness to Christ
# A miracle
# Three more miracles
# The Virgin and angels praying. This image faces the Christ Pantokrator lunette (#16 in this list), and Mary is labelled in Greek,  “Mother of God, container (''chora'') of the uncontainable (''achoritou'').” This phrase both refers to the theological paradox of Christ's dual nature, as well as the name of the monastery, the Chora.<ref name=":0" />
# Christ Pantokrator (or "Almighty," this image is in the lunette over the doorway to the inner narthex, and depicts Christ blessing the viewer with his right hand, and holding a jeweled Gospel in his left.) The label plays on the monastery's name, the Chora, in its reference to Christ as the "land of the living."<ref name=":0" /> This phrase comes from Psalm 116:9, used in the Orthodox funeral service, also significant because of the addition of the funerary spaces under Metochites, who anticipated burial in this monastery.<ref name=":0" />

====Esonarthex====
[[File:HSX Mary genealogy.jpg|thumb|Mosaic of the Virgin and Child, north dome of the inner narthex]]
[[File:Chora Christ south coupole.jpg|thumb|Mosaic of [[Christ Pantocrator]], south dome of the inner narthex]]

The esonarthex (or inner narthex) is similar to the exonarthex, running parallel to it. Like the exonarthex, the esonarthex is 4 m wide, but it is slightly shorter, 18 m long. Its central, eastern door opens into the naos, while another door at the southern end of the esonarthex opens into the rectangular antechamber of the parecclesion. At its northern end, a door from the esonarthex leads into a broad west–east corridor that runs along the northern side of the naos and into the [[Prothesis (altar)|prothesis]]. The esonarthex has two "pumpkin" domes. The smaller is above the entrance to the northern corridor; the larger is midway between the entrances into the naos and the pareclession, and they continue the emphasis on imagery of the Virgin and Christ seen elsewhere in these mosaics.<ref name=":0" />

# Enthroned Christ with [[Theodore Metochites]] presenting a model of his church. This image depicts Theodore in the traditional visual formula indicating that he is the donor, for this fourteenth-century leader was responsible for renovating the twelfth-century church as well as adding the parecclesion.<ref name=":0" />
# [[Saint Peter]]
# [[Paul the Apostle|Saint Paul]]
# A monumentally scaled mosaic of the ''[[Deesis]]'': Christ and the Virgin Mary (without John the Baptist) with two earlier donors below, Isaac Komnenos and a nun labeled “Melanie, the Lady of the Mongols,” who may be the daughter of emperor Michael VIII (reigned 1261–82).<ref name=":0" /> The subject matter and large scale probably alludes to a similar scene in the south gallery of the Hagia Sophia, installed soon after the [[Latin occupation]] of Constantinople (1204–61) ended.<ref name=":0" />
# The [[Genealogy of Jesus|genealogy of Christ]]
# Religious and noble ancestors of Christ

The mosaics in the first three bays of the inner narthex give an account of the [[life of the Virgin]], and those of her parents. Some of them are as follows:
# The rejection of [[Joachim|Joachim's]] offerings
# The annunciation to [[Saint Anne]]: the angel of the Lord announcing to Anne that her prayer for a child has been heard
# [[Joachim and Anne Meeting at the Golden Gate|The meeting of Joachim and Anne]]
# [[Nativity of Mary|The birth of the Virgin]]
# The first seven steps of the Virgin
# The Virgin given affection by her parents, this scene is more typical of the late Byzantine era, when artists were more inclined to explore emotional and/or everyday themes than artists in the early or middle Byzantine periods.<ref name=":0" />
# The Virgin blessed by the priests
# [[Presentation of Mary|The presentation of the Virgin in the Temple]]
# The Virgin receiving bread from an Angel
# The Virgin receiving the skein of purple wool, as the priests decided to have the attendant maidens weave a veil for the Temple
# [[Zechariah (priest)|Zechariah]] praying; when it was time for the Virgin to marry, the High Priest Zechariah called all the widowers together and placed their rods on the altar, praying for a sign showing to whom she should be given
# The Virgin entrusted to Joseph;
# Joseph taking the Virgin to his house;
# The [[Annunciation]] to the Virgin at the well.  This image, in which the young Mary awkwardly turns towards the approach of the archangel Gabriel, was adapted to triangular space in which it was depicted. There is a strong emphasis on images of Christ and Mary in the exonarthex and esonarthex.<ref name=":0" />
# Joseph leaving the Virgin; Joseph had to leave for six months on business and when he returned the Virgin was pregnant, arousing his suspicion.

===Naos===
The central doors of the esonarthex lead into the main body of the church, the ''naos''. The largest dome in the church (7.7 m in diameter) is above the centre of the naos. Two smaller domes flank the modest [[apse]]: the northern dome is over the [[Prothesis (altar)|prothesis]], which is linked by short passage to the [[bema]]; the southern dome is over the [[diaconicon]], which is reached via the parecclesion. Only three mosaics survive in the Chora's naos:

# ''Koimesis'' (the [[Dormition of Mary|Dormition of the Virgin]]; i.e. her last sleep before ascending to Heaven). Jesus is holding an infant, symbolic of Mary's soul.
# Jesus Christ
# ''Theotokos'' (the Virgin and Child), both the image of Christ (#2 in this list) and this mosaic of the Virgin originally were positioned as ''proskynetaria'' icons to flank the templon, the barrier which was in front of the sanctuary, though the templon no longer survives.<ref name=":0" />

===Parecclesion===
[[File:Chora Church Constantinople 2007 010.jpg|thumb|upright|View into the [[parecclesion]]]]
To the right of the esonarthex, doors open into the side chapel, or ''parecclesion''. The parecclesion was used as a mortuary chapel for family burials and memorials. The second largest dome (4.5 m diameter) in the church graces the centre of the roof of the parecclesion. A small passageway links the parecclesion directly into the naos, and off this passage can be found a small oratory and a storeroom. The parecclesion is covered in [[fresco]]es that emphasize the theological message of salvation, in keeping with the space's use as a funerary chapel.<ref name=":0" /> Within the Christian worldview, God raises the dead at the end of time, hence the significance of the Anastasis and Last Judgement scenes painted prominently on the ceiling. The image of the Anastasis is particularly renowned, appearing in many art history survey books as a key examplar of late Byzantine art.

# ''Anastasis'' (literally [[Resurrection of Jesus|Resurrection]])": the [[Harrowing of Hell]]. Christ, who has just broken down the gates of Hell, is standing in the centre and pulling [[Adam and Eve]] out of their tombs. Christ is adorned in vivid white garments as well as encircled by a radiant [[mandorla]], setting him in contrast to the dark colors of the fresco's background. Behind Adam stand John the Baptist, [[David]], and [[Solomon]], and other righteous kings. Below is the bound personification of [[Hades]], rendered as an African individual.
# The [[Last Judgment]], or [[Second Coming]]. Christ is enthroned with the Virgin and John the Baptist on either side of him. (This trio is also called the ''Deesis''.)
# Virgin and Child
# Heavenly court of angels
# Two panels of Moses
Along the walls of the Chora's parecclesion are [[Arcosolium|arcosolia]], arched recesses for tombs, likely intended for Theodore Metochites and his family. Also at this level are depictions of soldier saints, who wield swords as if protecting the tombs they accompany.<ref name=":0" /> <gallery widths="220" height="150">

==Restoration Interventions==
===Degradation and Pathologies===
Kariye Mosque has been subjected to different forms of degradation due to natural aging, unfit restoration works and change in its use. The most prevalent pathologies are the pigment loss in the interior wall paintings, the structural instability in the domes and vaults, the biological crusting on the brick facades, the water infiltration due to the deteriorated roofing.

New environmental stressors have been introduced during the post-2020 reconversion phase due to the high density of visitors and lack of HVAC systems. These new stressors primarily consist of condensation and limited airflow.

===Mid 20th Century Restoration (1947-1958)===

The campaigns considered to be the keystone of international restoration ethics were led
between 1947 and 1959 by the [[Dumbarton Oaks]] and [[Byzantine Institute of America|Byzantine Institute]]. The works done
exemplified the principles which later on would be codified in the [[Venice Charter]].

Brick facades were cleaned and re-pointed with lime-based mortars that are chemically
compatible with the original. The roofing system was restored with re-leaded coverings and improved in terms of the drainage. The re-connection of gutters and drainage systems led to solving the continuous rising damp and capillary salt action problems in fresco-bearing plasters. Aligning
with the Byzantine contours was prioritized during the works on drainage systems. The stabilization of the vault was done through the usage of stainless-steel rods. Reversibility was prioritised and thus were inserted without the usage of synthetic binders.

====Architectural Recoveries====
The rectification of what had been distorted by the 19th century works started by the reinstating of the [[Late Byzantine]] spatial rhythms on the cornices and dome profiles. Additionally,based on the archival sources, original fenestration was reinstated by re-opening the blocked windows. Later additions dating back to the [[Ottoman Empire|Ottoman Era]], such as the Ottoman floor tiles were dismantled. Whitewash and lime plasters from that period were also removed by scalpels from the frescoes and mosaics. The voids were filled by applying low pressure micro grouts behind the mosaics.

===Post-2020 Interventions (2020-2024): Functional Reuse and Conservation Challanges===

The reconversion of the structure into a mosque in 2020 made selective architectural interventions inevitable. While claiming reversibility, these '''interventions prioritized functional adaptation'''. However, not all were transparently reported, and all were found inadequate when matching the comprehensive conservation efforts.

====Key Interventions====
The priority was given to the roofing and wooden dome structure and replacing the deteriorated 19th century rubble fillings. Lightweight metal substructures were used in order to ease
the vault pressure and the lead roofing sections were renewed. Later on, the repointing of the façade focused on the south [[Parecclesion|parrekklesion]] (funerary space) and apse joints. They were treated using [[lime mortar]] and all the biological after cement residues from previous interventions were removed. Later,stone bricks were added. Tensioning the foundations for strengthening and the modelling of the structure was done and approved before all others were done.

The [[minaret]] was 'replastered by applying lime-bound plasters in order to address the surface
erosion problems and seal microcracks. However, the seismic retrofitting done in this period
remains undocumented. The repairs on the vault focused on the localized stitching of the microcracks and rod-reinforcements in the naos structure. These efforts are seen as the continuation of the efforts put in the 1950s campaign. Removal of dust layers on the surfaces of frescoes, marbles and mosaics using pure water and paper compress.

The recovery of the visual surface started with the reinterpretation of the façade elements
of [[Narthex|exonarthex]] and the removal of later additions. The eave was also slightly re-aligned in order to
reveal the [[Komnenian restoration|Komnenian]] layering. Finally, the surfaces were sprayed with water repellent solutions.

====Wall Painting Conservation Works====

The remaining lime-wash from the Ottoman era was removed through the use of manual and
solvent assisted procedures as to safeguard the underlying pigments. Mosaics were re-attached
with reversible micro-grouting. The missing individual pieces were replaced only when the legibility
or the structural integrity was impaired and was done following the distinguishability factor. The
detaching frescoes were grouted with mineral based injectable solutions that were customized
after substrate analysis and to remove soluble salts from the surface poultice desalination was

====Soft Interventions====
The conversion into a mosque gave rise to the need for an [[Aniconism in Islam|obstruction blocking the figural art during prayer]], so motorized blinds were installed. Although they technically are reversible, they reduce the mosaic visibility throughout the day. Prayer carpets were also laid, and the lighting was restrained. All of which affect the acoustic clarity and the vivid colour palette of the interior. The shift in its use introduced ablution moisture and body heat. The carpet insulation has increased humidity, causing condensation under domes and stress in painted layers.

==Name==
The original, 4th-century monastery containing the church was outside [[Constantinople]]'s city walls. Literally translated, the church's full name was the Church of the Holy Saviour in the Country ({{langx|el|ἡ Ἐκκλησία τοῦ Ἁγίου Σωτῆρος ἐν τῇ Χώρᾳ}}, ''hē Ekklēsia tou Hagiou Sōtēros en tēi Chōrāi''). It is therefore sometimes incorrectly referred to as "Saint Saviour". However, "The Church of the Holy Redeemer in the Fields" would be a more natural rendering of the name in English. The last part of the Greek name, Chora, referring to its location originally outside of the walls, became the shortened name of the church. The name must have carried symbolic meaning, as the mosaics in the narthex describe Christ as the "Land of the Living" ({{lang|grc|ἡ Χώρα τῶν ζώντων}}, ''hē Chōra tōn zōntōn'') and [[Mary, the mother of Jesus]], as the "Container of the Uncontainable" ({{lang|grc|ἡ Χώρα τοῦ Ἀχωρήτου}}, ''hē Chōra tou Achōrētou'').
