, Greek: Αγία Σοφία; "Holy Wisdom", Latin: Sancta Sophia
or Sancta Sapientia
) is a former patriarchal basilica, later a mosque, now a museum in Istanbul, Turkey. Famous in particular for its massive dome, it is considered the epitome of Byzantine architecture. It was the largest cathedral ever built in the world for nearly a thousand years, until the completion of the Seville Cathedral in 1520. The current building was originally constructed as a church between A.D. 532 and 537 on the orders of the Byzantine Emperor Justinian, and was in fact the third Church of the Holy Wisdom
to occupy the site (the previous two had both been destroyed by riots). It was designed by two architects, Isidore of Miletus and Anthemius of Tralles. The Church contained a large collection of holy relics and featured, among other things, a 50 foot (15 m) silver iconostasis. It was the patriarchal church of the Patriarch of Constantinople and the religious focal point of the Eastern Orthodox Church for nearly 1000 years.
In 1453, Constantinople was conquered by the Ottoman Turks and Sultan Mehmed II ordered the building to be converted into the Ayasofya Mosque. The bells, altar, iconostasis, and sacrificial vessels were removed, and many of the mosaics were eventually plastered over. The Islamic features such as the mihrab, the minbar, and the four minarets outside were added over the course of its history under the Ottomans. It remained as a mosque until 1935, when it was converted into a museum by the Republic of Turkey.
For almost 500 years the principal mosque of Istanbul, Hagia Sophia served as a model for many of the Ottoman mosques such as the Sultan Ahmed Mosque (Blue Mosque of Istanbul), the Şehzade Mosque, the Süleymaniye Mosque, and the Rüstem Pasha Mosque.
Although it is sometimes referred to as
(Greek for wisdom), the Greek name in full is Ναός τῆς Ἁγίας τοῦ Θεοῦ Σοφίας, Church of the Holy Wisdom of God
, and it was dedicated to the Holy Wisdom of God rather than a specific saint named Sophia. History First church Megálē Ekklēsíā
Nothing remains of the first church that was built on this location, known as the Μεγάλη Ἐκκλησία (
, "Great Church"), or in Latin "Magna Ecclesia". On Buildings
As often happened in those days, the site was selected because there had been a pagan temple there. The church was built next to the area where the imperial palace was being developed and next to the smaller church Hagia Eirene, finished first and acting as cathedral until the Hagia Sophia was completed. The Hagia Sophia was inaugurated by Constantius II on 15 February 360. Both churches acted together as the principal churches of the Byzantine Empire. Second church
This church was chronicled by Socrates of Constantinople (380440), who claimed that it was built by Constantine the Great. It was built as a traditional Latin colonnaded basilica with galleries and a wooden roof. It was preceded by an atrium. This first church was then already claimed to be one of the world's most outstanding monuments.
The appellation "Megálē Ekklēsíā" continued to be used for a long time, only to be replaced by the name "Hagia Sophia" after the conquest of Byzantium in 1453
The patriarch of Constantinople, John Chrysostom, came into a conflict with Empress Aelia Eudoxia, wife of the Emperor Arcadius and was sent into exile on 20 June 404. During the subsequent riots, this first church was largely burned down. A second church was ordered by Theodosius II, who inaugurated it on 10 October 405. The basilica with a wooden roof was built by architect Rufinos. Third church
The fire that started during the tumult of the Nika Revolt resulted in the destruction of the (second) Hagia Sophia, which burned down to the ground on 1314 January 532.
Several marble blocks from this second church have survived to the present day, and they are displayed in the garden of the current (third) church. The blocks were originally part of a monumental front entrance; they were excavated in the western courtyard by A.M. Schneider in 1935. The relief depicting 12 lambs 12 apostles as well as other remains of this church were discovered during excavation works in 1935. In order not to harm the present Hagia Sophia building, further excavation works were not carried out.
On February 23, 532, only a few days after the destruction of the second basilica, Emperor Justinian I took the decision to build a third and entirely different basilica, larger and more majestic than its predecessors.
Justinian chose the physicist Isidore of Miletus and the mathematician Anthemius of Tralles as architects; Anthemius, however, died within the first year. The construction is described by the Byzantine historian Procopius'
, Latin: De aedificiis
). The emperor had material brought over from all over the empire, such as Hellenistic columns from the temple of Artemis at Ephesus. Large stones were brought from far-away quarries: porphyry from Egypt, green marble from Thessaly, black stone from the Bosporus region and yellow stone from Syria. More than ten thousand people were employed during this construction. This new church was immediately recognized as a major work of architecture, demonstrating the creative insights of the architects. They may have used the theories of Heron of Alexandria to be able to construct a huge dome over such a large open space. The emperor, together with the patriarch Eutychius, inaugurated the new basilica on December 27, 537 with much pomp and circumstance. The mosaics inside the church were, however, only completed under the reign of Emperor Justin II (565578). Ekphrasis
Earthquakes in August 553 and on December 14, 557 caused -----s in the main dome and the eastern half-dome to appear. The main dome collapsed completely during an earthquake on May 7, 558, destroying the ambon, the altar and the ciborium over it. The emperor ordered an immediate restoration. He entrusted it to Isodorus the Younger, nephew of Isidore of Miletus. This time he used lighter materials and elevated the dome by 6.25 metres (20.5 ft), thus giving the building its current interior height of 55.6 metres (182 ft). . This reconstruction, giving the church its present 6th century form, was completed in 562. The Byzantine poet Paul the Silentiary composed an extant, long epic poem, known as
, for the rededication of the basilica, presided over by Patriarch Eutychius, on 23 December 562. citation needed
Hagia Sophia was the seat of the Orthodox patriarch of Constantinople and a principal setting for Byzantine imperial ceremonies, such as coronations. The basilica also offered asylum to wrongdoers. Foreign visitors were deeply impressed.
In 726 the Emperor Leo the Isaurian issued a series of edicts against the veneration of images, ordering the army to destroy all icons (iconoclasm). At that time, all religious pictures and statues were removed from the Hagia Sophia. After a brief reprieve under Empress Irene (797802), the iconoclasts made a comeback. Emperor Theophilus (829842) was strongly influenced by Islamic art,[
] which forbids graven images. He had a two-winged bronze door with his monograms installed at the southern entrance of the church. De caerimoniis aulae Byzantinae
The basilica suffered damage, first by a great fire in 859, and again by an earthquake on January 8, 869 that made a half-dome collapse. Emperor Basil I ordered the church to be repaired.
After the great earthquake of 25 October 989, which ruined the great dome of Hagia Sophia, the Byzantine emperor Basil II asked for the Armenian architect Trdat, creator of the great churches of Ani and Agine, to repair the dome.. His main repairs were to the western arch and a portion of the dome. The extent of the church's destruction meant that reconstruction lasted six years. The church was re-opened on 13 May 994.
In his book
(Book of Ceremonies), emperor Constantine VII (913919) wrote about all the details of the ceremonies held in the Hagia Sophia by the emperor and the patriarch. Şadirvan
At the capture of Constantinople during the Fourth Crusade, the church was ransacked and desecrated by the Latin Christians. The Byzantine historian Niketas Choniates described the capture of Constantinople. Many relics from the church, such as a stone from the tomb of Jesus, the Virgin Mary's milk, the shroud of Jesus, and bones of several saints, were sent to churches in the West and can be seen now in various museums in the West. During the Latin occupation of Constantinople (12041261) the church became a Roman Catholic cathedral. Baldwin I of Constantinople was crowned emperor on 16 May 1204 in the Hagia Sophia, at a ceremony which closely followed Byzantine practices. Enrico Dandolo, the Doge of Venice who commanded the sack and invasion of the city by the Latin Crusaders in 1204, is buried inside the church. The tomb inscription carrying his name, which has become a part of the floor decoration, was spat upon by many of the angry Byzantines who recaptured Constantinople in 1261. However, restoration carried out during the period 18471849 cast doubt upon the authenticity of the doge's grave. It is more likely a symbolic burial site to keep alive his memory. Mosque
After the recapture in 1261 by the Byzantines, the church was in a dilapidated state. The four buttresses in the west were probably built during this time. In 1317, emperor Andronicus II ordered four new buttresses to be built in the eastern and northern parts of the church. After new -----s had developed in the dome after the earthquake of October 1344, several parts of the building collapsed on 19 May 1346. After that, the church remained closed until 1354, when repairs were undertaken by the architects Astras and Peralta.
) for ritual ablutions mihrab
located in the apse where the altar used to stand, pointing towards Mecca medrese Immediately after the Ottoman Turks conquered Constantinople (Istanbul) in 1453, the Hagia Sophia was converted to the Ayasofya Mosque as the symbol of the conquest. At that time, the church was very dilapidated. Several of its doors had fallen off. This condition was described by several Western visitors, such as the Córdoban nobleman Pero Tafur and the Florentine Cristoforo Buondelmonti. The sultan Mehmed II ordered the immediate cleanup of the church and its conversion to a mosque. The next sultan Bayezid II built a new minaret, replacing the one built by his father. In the 16th century the sultan Suleiman the Magnificent (15201566) brought back two colossal candles from his conquest of Hungary. They were placed on both sides of the mihrab. During the reign of Selim II (15661577), the building started showing signs of fatigue and was extensively strengthened with the addition of structural supports to its exterior by the great Ottoman architect Sinan, who is also considered one of the world's first earthquake engineers . In addition to strengthening the historic Byzantine structure, Sinan built the two additional large minarets at the western end of the building, the original sultan's loge, and the mausoleum of Selim II to the southeast of the building (then a mosque) in 1577. The mausoleums of Murad III and Mehmed III were built next to it in the 1600s. Later additions were the sultan's gallery, a minbar decorated with marble, a dais for a sermon and a loggia for a muezzin. The sultan Murad III (15741595) had two large alabaster Hellenistic urns transported from Pergamon and placed on two sides of the nave. Sultan Mahmud I ordered the restoration of the building in 1739 and added a
(a Koranic school, now the library of the museum), a soup kitchen (for distribution to the poor) and a library, and in 1740 a fountain for ritual ablutions (Şadirvan
), thus transforming it into a külliye
, i.e. a social complex. At the same time a new sultan's gallery and a new mihrab were built inside. The most famous restoration of the Hagia Sophia was ordered by Sultan Abdülmecid and completed by eight hundred workers between 1847 and 1849, under the supervision of the Swiss-Italian architect brothers Gaspare and Giuseppe Fossati. The brothers consolidated the dome and vaults, straightened the columns, and revised the decoration of the exterior and the interior of the building. The mosaics in the upper gallery were cleaned. The old chandeliers were replaced by new pendant ones. New gigantic circular-framed disks were hung on columns. They were inscribed with the names of Allah, the prophet Muhammad, the first four caliphs Abu Bakr, Umar, Uthman and Ali, and the two grandchildren of Mohammed: Hassan and Hussain, by the calligrapher Kazasker İzzed Effendi (18011877). In 1850 the architect Fossati built a new sultan's gallery in a Neo-Byzantine style connected to the royal pavilion behind the mosque. Outside the Hagia Sophia, a timekeeper's building and a new medrese were built. The minarets were altered so that they were of equal height. When the restoration was finished, the mosque was re-opened with ceremonial pomp on 13 July 1849.  Museum
In 1935, the first Turkish President and founder of the Republic of Turkey, Mustafa Kemal Atatürk, transformed the building into a museum. The carpets were removed and the marble floor decorations appeared for the first time in centuries, while the white plaster covering the mosaics was painstakingly removed by expert restorers.
