sentences:  Little Hagia Sophia
  
  Little Hagia Sophia Mosque (), formerly the Church of Saints Sergius and Bacchus (, "Ekklēsía tôn Hagíōn Sergíou kaì Bákchou en toîs Hormísdou"), is a former Greek Eastern Orthodox church dedicated to Saints Sergius and Bacchus in Constantinople, built 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.
