Little Hagia Sophia, Mosque in Istanbul, Turkey
Little Hagia Sophia, originally known as the Church of the Saints Sergius and Bacchus, is a former Eastern Orthodox church dedicated to Saints Sergius and Bacchus in Constantinople.
Built around 530 AD by Justinian I, it was converted into a mosque during the Ottoman Empire.
The building reflects the innovative architectural style of the Byzantine period.
It's located in the district of Fatih, within walking distance from the Blue Mosque.
Despite its name, it's not a smaller version of the Hagia Sophia, but an entirely different building.
