Uzunköprü
12.7 km · Uzunköprü, formerly Cisr-i Ergene, is a 15th-century Ottoman stone bridge over the River Ergene in Edirne Province, northwestern Turkey. The bridge gave its name to the nearby town of Uzunköprü and is claimed to be the world's longest stone bridge. It was built to facilitate crossing the Ergene for troops during river floods, and to replace a wooden bridge; previous structures had rapidly deteriorated or had been destroyed.
