Hagia Sophia, officially the Hagia Sophia Grand Mosque, is a mosque, a former church, and 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 537 AD. The site was an Chalcedonian church from 360 AD to 1054, an Orthodox church following the Great Schism of 1054, and a Catholic church following the Fourth Crusade. It was reclaimed in 1261 and remained Eastern Orthodox until 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.
Hagia Sophia Church was built in 537 AD, with minarets added in the 15th–16th centuries when it became a mosque.
