The Old Bridge (Bulgarian: Стар мост, Star most) or Mustafa Pasha Bridge is a 16th-century arch bridge over the Maritsa in Svilengrad, southern Bulgaria. Completed in 1529, it was built on the order of the Ottoman vizier Çoban Mustafa Pasha. The bridge was the first major work designed by the Ottoman architect Mimar Sinan, and was part of a vakıf complex that also included a caravanserai, mosque, bazaar and hamam.
