The Iron Gate is a gorge on the Danube River. 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 Orşova, that contains two hydroelectric dams, with two power stations, Iron Gate I Hydroelectric Power Station and Iron Gate II Hydroelectric Power Station. The gorge lies between Romania in the north and Serbia in the south. At this point, the river separates the southern Carpathian Mountains from the northwestern foothills of the Balkan Mountains. The Romanian, Hungarian, Slovakian, Turkish, German and Bulgarian names literally mean "Iron Gates" and are used to name the entire range of gorges. An alternative Romanian name for the last part of the route is Clisura Dunării, "Danube Gorge". In Serbia, the gorge is known as Đerdap (Ђердап), with the last part named Đerdapska klisura (Ђердапска клисура). The Romanian side of the gorge constitutes the Iron Gates natural park; on the other bank, in Serbia, is the Đerdap national park. Source: Wiki
