Little Hagia Sophia

The Little Hagia Sophia mosque, formerly the Church of Saints Sergius and Bacchus, is a former Greek Orthodox church dedicated to the Syrian Christian Saints Sergius and Bacchus in Constantinople. Its date of construction is disputed, with some scholars favouring a mid-520s date with groundbreaking by 527 and others preferring to date its construction between 532 and 536, and converted into a mosque during the Ottoman Empire.
