Hagia Sophia (Greek: Αγία Σοφία, meaning 'the Holy Wisdom'; Turkish: Ayasofya) is a formerly Greek Orthodox church that was converted into a mosque following the conquest of Trabzon by Mehmed II in 1461. It is located in Trabzon, northeastern Turkey. It was converted into a museum in 1964 and back into a mosque in 2013. The building dates back to the thirteenth century, when Trabzon was the capital of the Empire of Trebizond. It is located near the seashore and two miles west of the medieval town's limits. It is one of a few dozen Byzantine sites extant in the area and has been described as being "one of the finest examples of Byzantine architecture".
