About Hagia Sophia

Hagia Sophia, officially the Hagia Sophia Grand Mosque, is a mosque and a major cultural and historical site in Istanbul, Turkey. It was formerly a church (360–1453) and a museum (1935–2020). The last of three church buildings to be successively erected on the site by the Eastern Roman Empire, it was completed in AD 537, becoming the world's largest interior space and among the first to employ a fully pendentive dome.

History

The first church on the site was known as the Magna Ecclesia (Μεγάλη Ἐκκλησία, Megálē Ekklēsíā, 'Great Church') because of its size compared to the sizes of the contemporary churches in the city. According to the Chronicon Paschale, the church was consecrated on 15 February 360, during the reign of the emperor Constantius II (r. 337–361) by the Arian bishop Eudoxius of Antioch.
