Hagia Sophia-The legacy of Byzantium
Hagia Sophia Cathedral (Holy wisdom) was build up by two Greek architects Anthemius and Isidorus during the reign of Emperor Justinian.

Hagia Sophia (from the Greek: Ἁγία Σοφία, "Holy Wisdom"; Latin: Sancta Sophia or Sancta Sapientia; Turkish: Aya Sofya) is a former Orthodox patriarchal basilica, later a mosque, and now a museum in Istanbul, Turkey. From the date of its dedication in 360 until 1453, it served as the cathedral of Constantinople, except between 1204 and 1261, when it was converted to a Roman Catholic cathedral under the Latin Patriarch of Constantinople of the Western Crusader established Latin Empire. The building was a mosque from 29 May 1453 until 1934, when it was secularized. It was opened as a museum on 1 February 1935









Hagia Sophia (Άγια Σοφία in Greek), the Church of Holy Wisdom, known variously as Sancta Sophia in Latin or Ayasofya in Turkish, is an ancient cathedral of the Church of Constantinople located in modern-day Istanbul, Turkey. It was converted to a mosque by the Turks and is now used as a museum. It is universally acknowledged as one of the great buildings of the world and a reference point in history of architecture. (The church is sometimes mistakenly called "Saint Sophia," as though it were named for a saint called Sophia.)

The first great church on the site was built by Constantius II, the son of Constantine the Great, but was burned down during the Nika riots of 532. The building was rebuilt in its present form between 532 and 537 under the personal supervision of emperor Justinian the Great. It is one of the greatest surviving examples of Byzantine architecture. Of great artistic value was its decorated interior with mosaics and marble pillars and coverings. The temple itself was so richly and artistically decorated that Justinian is believed to have said Νενίκηκά σε Σολομών: "Solomon, I have surpassed you!"
Interior of Hagia Sophia

The architects of the church were Isidore of Miletus and Anthemius of Tralles, professors of geometry at the University of Constantinople. Justinian's basilica was at once the culminating architectural achievement of late antiquity and the first masterpiece of Byzantine architecture. Its influence, both architecturally and liturgically, was widespread and enduring in the Orthodox, Roman Catholic, and Muslim worlds alike.

Hagia Sophia is covered by a central dome with a diameter of 31 meters (102 feet), slightly smaller than the Pantheon's. The dome seems rendered weightless by the unbroken arcade of arched windows under it, which help flood the colorful interior with light. The dome is carried on pendentives: four concave triangular sections of masonry which solve the problem of setting the circular base of a dome on a rectangular base. In Hagia Sophia the weight of the dome passes through the pendentives to four massive piers at the corners. Between them the dome seems to float upon four great arches.

At the western (entrance) and eastern (liturgical) ends, the arched openings are extended by half domes carried on smaller semidomed exedras. Thus a hierarchy of dome-headed elements build up to create a vast oblong interior crowned by the main dome, a sequence unexampled in antiquity.

The structure has been severely damaged several times by earthquakes. The dome collapsed after an earthquake in 558; its replacement fell in 563. There were additional partial collapses in 989 and 1346.

All interior surfaces are sheathed with polychrome marbles, green and white with purple porphyry and gold mosaics, encrusted upon the brick. On the exterior, simple stuccoed walls reveal the clarity of massed vaults and dome.

For over 900 years the Hagia Sophia was the seat of the Patriarch of Constantinople and a principal setting for imperial ceremonies. It was converted to a mosque at the Fall of Constantinople to the Ottoman Turks under Sultan Mehmet II in 1453. Since Islam considers the depiction of the human form to be blasphemous— that is, it is iconoclastic—Hagia Sophia's iconographic mosaics were covered with plaster. For almost 500 years the principal mosque of Istanbul, Ayasofya, served as model for many of the Ottoman mosques of Constantinople such as the Shehzade Mosque, the Suleiman Mosque, and the Rustem Pasha Mosque.
