Little Hagia Sophia

The Little Hagia Sophia mosque, formerly the Church of Saints Sergius and Bacchus (Ancient Greek: Ἐκκλησία τῶν Ἁγίων Σεργίου καὶ Βάκχου ἐν τοῖς Ὁρμίσδου, romanized: Ekklēsía tôn Hagíōn Sergíou kaì Bákchou en toîs Hormísdou), is a former Greek Orthodox church dedicated to the Syrian Christian Saints Sergius and Bacchus in Constantinople (modern Istanbul). 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. This Byzantine building with a central dome plan was erected in the sixth century by Justinian; despite its Turkish name, it likely was not a model for Hagia Sophia ("Holy Wisdom"), with which its construction was contemporary, but it is nonetheless one of the most important early Byzantine buildings in Istanbul.
