Hagia Sophia (from the Greek: á¼Î³Î¯Î± ÏÎ¿ÏÎ¯Î±, Byzantine Greek [aËÊia soËfia]), Holy Wisdom; Latin: Sancta Sophia or Sancta Sapientia; Turkish: Ayasofya) was a Greek Orthodox Christian patriarchal basilica (church), later an imperial mosque, and now a museum (Ayasofya MÃ¼zesi) in Istanbul, Turkey.
Both names, Megale Ekklesia and Hagia Sophia are used today. The original Church was destroyed in 404 AD by mobs, during the riots, when Emperor Arcadius sent the Patriarch of Constantinople, John Chrysostom, into exile for his open criticism of the Empress.
