The Church of the Virgin Mary was the first of churches dedicated to the mother of Christ. It is also the most significant building from Christian times in Ephesus. It was erected in the 3rd century within an earlier building. Architecturally, the structure can be described as a basilica with a nave and two aisles. The aisles were divided into shorter parts, which could serve as shops. Today, the best-preserved section of the structure is a cylindrical baptistery, located in the northern part of the atrium. In the central part of the baptistery, there was a pool, where the baptised people could be fully immersed in water.

When the Ottoman army conquered Hadrianopolis around 1361, there were two main districts of the city, on two banks of the Tunca River. Kaleiçi was situated on the eastern bank, while Aina - on the western bank of the river. Not surprisingly, shortly after the capture of the city, Sultan Murat I ordered the construction of the first mosque in Edirne, as the settlement was to be called from that time. This is a short story of the first imperial mosque of the city - Hüdavendigâr Mosque, situated in Aina District.
