The Iron Gates (Serbian: Ђердапска клисура / Đerdapska klisura; Romanian: Porțile de Fier) is a gorge on the river Danube. It forms part of the boundary between Serbia (to the south) and Romania (north). 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 currently contains two hydroelectric dams, with two power stations. At this point in the Danube, the river separates the southern Carpathian Mountains from the northwestern foothills of the Balkan Mountains. The Romanian side of the gorge constitutes the Iron Gates Natural Park (Parcul Natural Porțile de Fier), whereas the Serbian part constitutes the Đerdap National Park (Национални парк Ђердап / Nacionalni park Đerdap). A wider protected area on the Serbian side was declared the UNESCO global geopark in July 2020.
