The Arda (Bulgarian: Арда, Greek: Αρδας, Ardas) is a river whose source lies in the Bulgarian Rhodope Mountains near the town of Smolyan, flowing 290 kilometres eastward past Kardzhali and Ivaylovgrad and through Greece in the northern portion of the Evros prefecture including Kastanies. It then enters the Maritsa, just west of Edirne, Turkey. The portion in Bulgaria is accented by three hydroelectric and irrigation dams, Kardzhali Dam, Studen Kladenets and Ivaylovgrad Dam, and is 241 km long, making the Arda the longest river in the Rhodopes. The medieval Dyavolski most arch bridge crosses the river 10 km from Ardino.
