After the conquest of Adrianople by the Ottoman army led by Sultan Murat I in 1365, the city became the capital of the Ottoman Empire. It lost its exceptional status only after the Turks conquered Constantinople in 1453. The Saray Baths (tr. Saray Hamamı) is one of the few remaining structures of the Old Edirne Palace, erected in the 14th century.

This Roman bridge, beautifully situated over deep Köprülü Canyon, is an irrefutable proof of Roman engineers' ingenuity. The bridge, spanning the cliffs of the canyon, is now called Oluk Köprü (i.e. Gutter Bridge). It still provides the communication link on the route from the Mediterranean coast deep into the Taurus Mountains, to the area of ancient Pisidia.
