Construction of Hagia Sophia

537 CE

Hagia Sophia was built in Constantinople for the Byzantine emperor Justinian I after the Nika riots of 532 destroyed the previous church. The architects Anthemius of Tralles and Isidore of Miletus designed a vast building crowned by a massive central dome, and the work was completed in under six years, an astonishing speed. For almost a thousand years it was the main church of Eastern Christianity, apart from a period under Latin rule after the Fourth Crusade. After the Ottoman conquest of 1453 it was converted into a mosque, with minarets added. In 1935 it became a museum under the Turkish Republic, and in 2020 it was reconverted into a mosque, a decision that drew both support and criticism.
