The Hagia Sophia

"Hagia Sophia (Church of Holy Wisdom), now known as the Ayasofya Museum, is a former Eastern Orthodox church converted to a mosque in 1453, converted into a museum in 1935, in the Turkish city of Istanbul. It is universally acknowledged as one of the greatest buildings of the world and sometimes considered the Eighth Wonder of the World. Its conquest by the Ottomans at the fall of Constantinople is considered one of the great tragedies of Christendom by the Greek Orthodox faithful."
