The Hagia Sophia’s stunning Byzantine architecture reveals its former life as a church (1260–1461), and features biblical frescoes from this period. The church was converted to a mosque during the Ottoman era, and later turned into a museum (1964). Today you can visit and see the frescoes, though most were concealed, according to Islamic tradition, when the main hall was reconverted into a mosque in 2013.
