Hagia Sophia (Constantinople)
Hagia Sophia (Άγια Σοφία in Greek), the Church of Holy Wisdom, known variously as Sancta Sophia in Latin or Ayasofya in Turkish, is an ancient cathedral of the Church of Constantinople located in modern-day Istanbul, Turkey. It was converted to a mosque by the Turks and is now used as a museum. It is universally acknowledged as one of the great buildings of the world and a reference point in history of architecture. (The church is sometimes mistakenly called "Saint Sophia," as though it were named for a saint called Sophia.)
