Mosque and former church in Istanbul, Turkey
Hagia Sophia,[a] officially the Hagia Sophia Grand Mosque,[b] is a mosque and former church serving as a major cultural and historical site in Istanbul, Turkey. The last of three church buildings to be successively erected on the site by the Eastern Roman Empire, it was completed in AD 537. The site was an Eastern rite church from AD 360 to 1453, except for a brief time as a Latin Catholic church between the Fourth Crusade and 1261.[4] After the fall of Constantinople in 1453, it served as a mosque until 1935, when it became a museum. In 2020, the site once again became a mosque.
The current structure was built by the Byzantine emperor Justinian I as the Christian cathedral of Constantinople for the Byzantine Empire between 532 and 537, and was designed by the Greek geometers Isidore of Miletus and Anthemius of Tralles.[5] It was formally called the Church of God's Holy Wisdom (Greek: Ναὸς τῆς Ἁγίας τοῦ Θεοῦ Σοφίας, romanized: Naòs tês Hagías toû Theoû Sophías)[6][7] and upon completion became the world's largest interior space and among the first to employ a fully pendentive dome. It is considered the epitome of Byzantine architecture[8] and is said to have "changed the history of architecture".[9] The present Justinianic building was the third church of the same name to occupy the site, as the prior one had been destroyed in the Nika riots. As the episcopal see of the ecumenical patriarch of Constantinople, it remained the world's largest cathedral for nearly a thousand years, until the Seville Cathedral was completed in 1520. Beginning with subsequent Byzantine architecture, Hagia Sophia became the paradigmatic Orthodox church form, and its architectural style was emulated by Ottoman mosques a thousand years later.[10] It has been described as "holding a unique position in the Christian world"[10] and as an architectural and cultural icon of Byzantine and Eastern Orthodox civilization.[10][11][12]
The religious and spiritual centre of the Eastern Orthodox Church for nearly one thousand years, the church was dedicated to the Holy Wisdom.[13][14][15] It was where the excommunication of Patriarch Michael I Cerularius was officially delivered by Humbert of Silva Candida, the envoy of Pope Leo IX in 1054, an act considered the start of the East–West Schism. In 1204, it was converted during the Fourth Crusade into a Catholic cathedral under the Latin Empire, before being returned to the Eastern Orthodox Church upon the restoration of the Byzantine Empire in 1261. Enrico Dandolo, the doge of Venice who led the Fourth Crusade and the 1204 Sack of Constantinople, was buried in the church.
After the fall of Constantinople to the Ottoman Empire in 1453,[16] it was converted to a mosque by Mehmed the Conqueror and became the principal mosque of Istanbul until the 1616 construction of the Sultan Ahmed Mosque.[17][18] Upon its conversion, the bells, altar, iconostasis, ambo, and baptistery were removed, while iconography, such as the mosaic depictions of Jesus, Mary, Christian saints and angels were removed or plastered over.[19] Islamic architectural additions included four minarets, a minbar and a mihrab. The Byzantine architecture of the Hagia Sophia served as inspiration for many other religious buildings including the Hagia Sophia in Thessaloniki, Panagia Ekatontapiliani, the Şehzade Mosque, the Süleymaniye Mosque, the Rüstem Pasha Mosque and the Kılıç Ali Pasha Complex. The patriarchate moved to the Church of the Holy Apostles, which became the city's cathedral.
The complex remained a mosque until 1931, when it was closed to the public for four years. It was re-opened in 1935 as a museum under the secular Republic of Turkey, and the building was Turkey's most visited tourist attraction as of 2019[update].[20]
In July 2020, the Council of State annulled the 1934 decision to establish the museum, and the Hagia Sophia was reclassified as a mosque. The 1934 decree was ruled to be unlawful under both Ottoman and Turkish law as Hagia Sophia's waqf, endowed by Sultan Mehmed, had designated the site a mosque; proponents of the decision argued the Hagia Sophia was the personal property of the sultan. The decision to designate Hagia Sophia as a mosque was highly controversial. It resulted in divided opinions and drew condemnation from the Turkish opposition, UNESCO, the World Council of Churches and the International Association of Byzantine Studies, as well as numerous international leaders, while several Muslim leaders in Turkey and other countries welcomed its conversion into a mosque.
Northern tympanum mosaics
The northern tympanum mosaics feature various saints. They have been able to survive due to their high and inaccessible location. They depict Patriarchs of Constantinople John Chrysostom and Ignatios of Constantinople standing, clothed in white robes with crosses, and holding richly jewelled Bibles. The figures of each patriarch, revered as saints, are identifiable by labels in Greek. The other mosaics in the other tympana have not survived probably due to the frequent earthquakes, as opposed to any deliberate destruction by the Ottoman conquerors.[279]
The dome was decorated with four non-identical figures of the six-winged angels which protect the Throne of God; it is uncertain whether they are seraphim or cherubim. The mosaics survive in the eastern part of the dome, but since the ones on the western side were damaged during the Byzantine period, they have been renewed as frescoes. During the Ottoman period each seraph's (or cherub's) face was covered with metallic lids in the shape of stars, but these were removed to reveal the faces during renovations in 2009.[280]
Southwestern entrance mosaic
The southwestern entrance mosaic, situated in the tympanum of the southwestern entrance, dates from the reign of Basil II.[260] It was rediscovered during the restorations of 1849 by the Fossatis. The Virgin sits on a throne without a back, her feet resting on a pedestal, embellished with precious stones. The Christ Child sits on her lap, giving his blessing and holding a scroll in his left hand. On her left side stands emperor Constantine in ceremonial attire, presenting a model of the city to Mary. The inscription next to him says: "Great emperor Constantine of the Saints". On her right side stands emperor Justinian I, offering a model of the Hagia Sophia. The medallions on both sides of the Virgin's head carry the nomina sacra MP and ΘΥ, abbreviations of the Greek: Μήτηρ του Θεοῦ, romanized: Mētēr Theou, lit. 'Mother of God'.[261] The composition of the figure of the Virgin enthroned was probably copied from the mosaic inside the semi-dome of the apse inside the liturgical space.[262]
The mosaic in the semi-dome above the apse at the east end shows Mary, mother of Jesus holding the Christ Child and seated on a jewelled thokos backless throne.[262] Since its rediscovery after a period of concealment in the Ottoman era, it "has become one of the foremost monuments of Byzantium".[262] The infant Jesus's garment is depicted with golden tesserae.
Guillaume-Joseph Grelot, who had travelled to Constantinople, in 1672 engraved and in 1680 published in Paris an image of the interior of Hagia Sophia which shows the apse mosaic indistinctly.[262] Together with a picture by Cornelius Loos drawn in 1710, these images are early attestations of the mosiac before it was covered towards the end of the 18th century.[262] The mosaic of the Virgin and Child was rediscovered during the restorations of the Fossati brothers in 1847–1848 and revealed by the restoration of Thomas Whittemore in 1935–1939.[262] It was studied again in 1964 with the aid of scaffolding.[262][263]
It is not known when this mosaic was installed.[262] According to Cyril Mango, the mosaic is "a curious reflection on how little we know about Byzantine art".[264] The work is generally believed to date from after the end of Byzantine Iconoclasm and usually dated to the patriarchate of Photius I (r. 858–867, 877–886) and the time of the emperors Michael III (r. 842–867) and Basil I (r. 867–886).[262] Most specifically, the mosaic has been connected with a surviving homily known to have been written and delivered by Photius in the cathedral on 29 March 867.[262][265][266][267][268]
Other scholars have favoured earlier or later dates for the present mosaic or its composition. Nikolaos Oikonomides pointed out that Photius's homily refers to a standing portrait of the Theotokos – a Hodegetria – while the present mosaic shows her seated.[269] Likewise, a biography of the patriarch Isidore I (r. 1347–1350) by his successor Philotheus I (r. 1353–1354, 1364–1376) composed before 1363 describes Isidore seeing a standing image of the Virgin at Epiphany in 1347.[262] Serious damage was done to the building by earthquakes in the 14th century, and it is possible that a standing image of the Virgin that existed in Photius's time was lost in the earthquake of 1346, in which the eastern end of Hagia Sophia was partly destroyed.[270][262] This interpretation supposes that the present mosaic of the Virgin and Child enthroned is of the late 14th century, a time in which, beginning with Nilus of Constantinople (r. 1380–1388), the patriarchs of Constantinople began to have official seals depicting the Theotokos enthroned on a thokos.[271][262]
Still other scholars have proposed an earlier date than the later 9th century. According to George Galavaris, the mosaic seen by Photius was a Hodegetria portrait which after the earthquake of 989 was replaced by the present image not later than the early 11th century.[271][270] According to Oikonomides however, the image in fact dates to before the Triumph of Orthodoxy, having been completed c. 787–797, during the iconodule interlude between the First Iconoclast (726–787) and the Second Iconoclast (814–842) periods.[269] Having been plastered over in the Second Iconoclasm, Oikonomides argues a new, standing image of the Virgin Hodegetria was created above the older mosaic in 867, which then fell off in the earthquakes of the 1340s and revealed again the late 8th-century image of the Virgin enthroned.[269]
More recently, analysis of a hexaptych menologion icon panel from Saint Catherine's Monastery at Mount Sinai has determined that the panel, showing numerous scenes from the life of the Virgin and other theologically significant iconic representations, contains an image at the centre very similar to that in Hagia Sophia.[262] The image is labelled in Greek merely as: Μήτηρ Θεοῦ, romanized: Mētēr Theou, lit. 'Mother of God', but in the Georgian language the inscription reveals the image is labelled "of the semi-dome of Hagia Sophia".[262] This image is therefore the oldest depiction of the apse mosaic known and demonstrates that the apse mosaic's appearance was similar to the present day mosaic in the late 11th or early 12th centuries, when the hexaptych was inscribed in Georgian by a Georgian monk, which rules out a 14th-century date for the mosaic.[262]
The portraits of the archangels Gabriel and Michael (largely destroyed) in the bema of the arch also date from the 9th century. The mosaics are set against the original golden background of the 6th century. These mosaics were believed to be a reconstruction of the mosaics of the 6th century that were previously destroyed during the iconoclastic era by the Byzantines of that time, as represented in the inaugural sermon by the patriarch Photios. However, no record of figurative decoration of Hagia Sophia exists before this time.[272]
Works influenced by the Hagia Sophia
Many buildings have been modeled on the Hagia Sophia's core structure of a large central dome resting on pendentives and buttressed by two semi-domes.
Byzantine churches influenced by the Hagia Sophia include the Hagia Sophia in Thessaloniki, and the Hagia Irene. The latter was remodeled to have a dome similar to the Hagia Sophia's during the reign of Justinian.
Several mosques commissioned by the Ottoman dynasty have plans based on the Hagia Sophia, including the Süleymaniye Mosque and the Bayezid II Mosque.[281][282] Ottoman architects preferred to surround the central dome with four semi-domes rather than two.[283] There are four semi-domes on the Sultan Ahmed Mosque, the Fatih Mosque,[284] and the New Mosque (Istanbul). As with the original plan of the Hagia Sophia, these mosques are entered through colonnaded courtyards. However, the courtyard of the Hagia Sophia no longer exists.
Neo-Byzantine churches modeled on the Hagia Sophia include the Kronstadt Naval Cathedral, Holy Trinity Cathedral, Sibiu[285] and Poti Cathedral. Each closely replicates the internal geometry of the Hagia Sophia. The layout of the Kronstadt Naval Cathedral is nearly identical to the Hagia Sophia in size and geometry. Its marble revetment also mimics the style of the Hagia Sophia.
As with Ottoman mosques, several churches based on the Hagia Sophia include four semi-domes rather than two, such as the Church of Saint Sava in Belgrade.[286][287] The Catedral Metropolitana Ortodoxa in São Paulo and the Église du Saint-Esprit (Paris) both replace the two large tympanums beneath the main dome with two shallow semi-domes. The Église du Saint-Esprit is two thirds the size of the Hagia Sophia.
Several churches combine elements of the Hagia Sophia with a Latin cross plan. For instance, the transept of the Cathedral Basilica of Saint Louis (St. Louis) is formed by two semi-domes surrounding the main dome. The church's column capitals and mosaics also emulate the style of the Hagia Sophia. Other examples include the Alexander Nevsky Cathedral, Sofia, St Sophia's Cathedral, London, Saint Clement Catholic Church, Chicago, and the Basilica of the National Shrine of the Immaculate Conception.
Synagogues based on the Hagia Sophia include the Congregation Emanu-El (San Francisco),[288] Great Synagogue of Florence, and Hurva Synagogue.

Church of Theodosius II
A second church on the site was ordered by Theodosius II (r. 402–450), who inaugurated it on 10 October 415.[36] The Notitia Urbis Constantinopolitanae, a fifth-century list of monuments, names Hagia Sophia as Magna Ecclesia, 'Great Church', while the former cathedral Hagia Irene is referred to as Ecclesia Antiqua, 'Old Church'. At the time of Socrates of Constantinople around 440, "both churches [were] enclosed by a single wall and served by the same clergy".[25] Thus, the complex would have encompassed a large area including the future site of the Hospital of Samson.[35] If the fire of 404 destroyed only the 4th-century main basilica church, then the 5th century Theodosian basilica could have been built surrounded by a complex constructed primarily during the fourth century.[35]
During the reign of Theodosius II, the emperor's elder sister, the Augusta Pulcheria (r. 414–453) was challenged by the patriarch Nestorius (r. 10 April 428 – 22 June 431).[37][38] The patriarch denied the Augusta access to the sanctuary of the "Great Church", likely on 15 April 428.[38] According to the anonymous Letter to Cosmas, the virgin empress, a promoter of the cult of the Virgin Mary who habitually partook in the Eucharist at the sanctuary of Nestorius's predecessors, claimed right of entry because of her equivalent position to the Theotokos – the Virgin Mary – "having given birth to God".[39][38] Their theological differences were part of the controversy over the title theotokos that resulted in the Council of Ephesus and the stimulation of Monophysitism and Nestorianism, a doctrine, which like Nestorius, rejects the use of the title.[37] Pulcheria along with Pope Celestine I and Patriarch Cyril of Alexandria had Nestorius overthrown, condemned at the ecumenical council, and exiled.[39][37]
The area of the western entrance to the Justinianic Hagia Sophia revealed the western remains of its Theodosian predecessor, as well as some fragments of the Constantinian church.[35] German archaeologist Alfons Maria Schneider began conducting archaeological excavations during the mid-1930s, publishing his final report in 1941.[35] Excavations in the area that had once been the 6th-century atrium of the Justinianic church revealed the monumental western entrance and atrium, along with columns and sculptural fragments from both 4th- and 5th-century churches.[35] Further digging was abandoned for fear of harming the structural integrity of the Justinianic building, but parts of the excavation trenches remain uncovered, laying bare the foundations of the Theodosian building.
The basilica was built by architect Rufinus.[40][41] The church's main entrance, which may have had gilded doors, faced west, and there was an additional entrance to the east.[42] There was a central pulpit and likely an upper gallery, possibly employed as a matroneum (women's section).[42] The exterior was decorated with elaborate carvings of rich Theodosian-era designs, fragments of which have survived, while the floor just inside the portico was embellished with polychrome mosaics.[35] The surviving carved gable end from the centre of the western façade is decorated with a cross-roundel.[35] Fragments of a frieze of reliefs with 12 lambs representing the 12 apostles also remain; unlike Justinian's 6th-century church, the Theodosian Hagia Sophia had both colourful floor mosaics and external decorative sculpture.[35]
At the western end, surviving stone fragments of the structure show there was vaulting, at least at the western end.[35] The Theodosian building had a monumental propylaeum hall with a portico that may account for this vaulting, which was thought by the original excavators in the 1930s to be part of the western entrance of the church itself.[35] The propylaeum opened onto an atrium which lay in front of the basilica church itself. Preceding the propylaeum was a steep monumental staircase following the contours of the ground as it sloped away westwards in the direction of the Strategion, the Basilica, and the harbours of the Golden Horn.[35] This arrangement would have resembled the steps outside the atrium of the Constantinian Old St Peter's Basilica in Rome.[35] Near the staircase, there was a cistern, perhaps to supply a fountain in the atrium or for worshippers to wash with before entering.[35]
The 4th-century skeuophylakion was replaced in the 5th century by the present-day structure, a rotunda constructed of banded masonry in the lower two levels and of plain brick masonry in the third.[35] Originally this rotunda, probably employed as a treasury for liturgical objects, had a second-floor internal gallery accessed by an external spiral staircase and two levels of niches for storage.[35] A further row of windows with marble window frames on the third level remain bricked up.[35] The gallery was supported on monumental consoles with carved acanthus designs, similar to those used on the late 5th-century Column of Leo.[35] A large lintel of the skeuophylakion's western entrance – bricked up during the Ottoman era – was discovered inside the rotunda when it was archaeologically cleared to its foundations in 1979, during which time the brickwork was also repointed.[35] The skeuophylakion was again restored in 2014 by the Vakıflar.[35]
A fire started during the tumult of the Nika Revolt, which had begun nearby in the Hippodrome of Constantinople, and the second Hagia Sophia was burnt to the ground on 13–14 January 532. The court historian Procopius wrote:[43]
And by way of shewing that it was not against the Emperor alone that they [the rioters] had taken up arms, but no less against God himself, unholy wretches that they were, they had the hardihood to fire the Church of the Christians, which the people of Byzantium call "Sophia", an epithet which they have most appropriately invented for God, by which they call His temple; and God permitted them to accomplish this impiety, foreseeing into what an object of beauty this shrine was destined to be transformed. So the whole church at that time lay a charred mass of ruins.
— Procopius, De aedificiis, I.1.21–22

Hagia Sophia Museum
Mustafa Kemal Ataturk, the first president of the Turkish Republic, turned Hagia Sophia into a museum in 1934, making it a destination for millions of tourists who visit it to enjoy the beauty of the mixture of Islamic and Christian decorations and ornaments.
The Viking Inscription
In the southern section of Hagia Sophia, a 9th-century Viking inscription has been discovered, which reads, "Halvdan was here." It is theorized that the inscription was created by a Viking soldier serving as a mercenary in the Eastern Roman Empire.[249]
The first mosaics which adorned the church were completed during the reign of Justin II.[250] Many of the non-figurative mosaics in the church come from this period. Most of the mosaics, however, were created in the 10th and 12th centuries,[251][better source needed] following the periods of Byzantine Iconoclasm.
During the Sack of Constantinople in 1204, the Latin Crusaders vandalized valuable items in every important Byzantine structure of the city, including the golden mosaics of the Hagia Sophia. Many of these items were shipped to Venice, whose Doge Enrico Dandolo had organized the invasion and sack of Constantinople after an agreement with Prince Alexios Angelos, the son of a deposed Byzantine emperor.
How to Get to Hagia Sophia?
Hagia Sophia is located in the Sultan Ahmed district, easily reached by the tramway. Visitors can get by tramway and head towards Sultan Ahmed station; the mosque is a 5-minute walk from the station. Or they can use any taxi to get there.
Loggia of the Empress
The loggia of the empress is located in the centre of the gallery of the Hagia Sophia, above the Imperial Gate and directly opposite the apse. From this matroneum (women's gallery), the empress and the court-ladies would watch the proceedings down below. A green stone disc of verd antique marks the spot where the throne of the empress stood.[241][242]
Two huge marble lustration (ritual purification) urns were brought from Pergamon during the reign of Sultan Murad III. They are from the Hellenistic period and carved from single blocks of marble.[19]
The Marble Door inside the Hagia Sophia is located in the southern upper enclosure or gallery. It was used by the participants in synods, who entered and left the meeting chamber through this door. It is said[by whom?] that each side is symbolic and that one side represents heaven while the other represents hell. Its panels are covered in fruits and fish motifs. The door opens into a space that was used as a venue for solemn meetings and important resolutions of patriarchate officials.[243]
The Nice Door is the oldest architectural element found in the Hagia Sophia dating back to the 2nd century BC. The decorations are of reliefs of geometric shapes as well as plants that are believed to have come from a pagan temple in Tarsus in Cilicia, part of the Cibyrrhaeot Theme in modern-day Mersin Province in south-eastern Turkey. It was incorporated into the building by Emperor Theophilos in 838 where it is placed in the south exit in the inner narthex.[244]
The Imperial Gate is the door that was used solely by the Emperor and his personal bodyguard and retinue.[227] It is the largest door in the Hagia Sophia and has been dated to the 6th century. It is about 7 meters long and Byzantine sources say it was made with wood from Noah's Ark.[245]
In April 2022, the door was vandalised by unknown assailant(s). The incident became known after the Association of Art Historians published a photo with the destruction. The Greek Foreign Ministry condemned the incident, while Turkish officials claimed that "a citizen has taken a piece of the door" and started an investigation.[246]
At the northwest of the building, there is a column with a hole in the middle covered by bronze plates. This column goes by different names; the "perspiring" or "sweating column", the "crying column", or the "wishing column". Legend states that it has been moist since the appearance of Gregory Thaumaturgus near the column in 1200. It is believed that touching the moisture cures many illnesses.[247][248]
