The Cathedral of Saint Sofia (sometimes known as Hagia Sophia or Sancta Sophia) in Istanbul (formerly Constantinople) was a basilica of the Eastern Orthodox Church for most of the period 360-1453. It then functioned as a mosque until 1934, at which point it was secularized and re-opened as a museum.
