The Fethiye Mosque is located on the northern side of the ancient Roman Agora in Athens, near the Tower of the Winds, and was built on the ruins of a Christian basilica from the middle Byzantine period (8th/9th centuries).

[1][2] The Christian church was converted into a mosque in 1456/58, soon after the Ottoman conquest of the Duchy of Athens, to coincide with the visit to the city by Sultan Mehmed the Conqueror in 1458.

The porch is supported by five arches, each crowned by a small dome, resting on masonry on the sides and four pillars in the middle.

In autumn 2010, the Greek Ministry of Culture ordered the emptying of the building from the various antiquities stored there, and the beginning of the process to restore it and open it to the public.

[9] The decision was sanctioned by Greece's Central Archaeological Council in 2013, paving the way for its restoration and its opening to the public as a space for cultural events.
