The Iron Gates (Romanian: Porțile de Fier, Serbian: Đerdapska klisura, Hungarian: Vaskapu-szoros, German: Eisernes Tor, Turkish: Demirkapı) is a gorge on the River Danube. It forms part of the boundary between Serbia and Romania. In the broad sense it encompasses a route of 134 km (83 mi); in the narrow sense it only encompasses the last barrier on this route, just beyond the Romanian city of Orșova, that contains two hydroelectric dams, with two power stations, Iron Gate I Hydroelectric Power Station and Iron Gate II Hydroelectric Power Station.
