The Iron Gate is a gorge on the river Danube. It forms part of the boundary between Serbia (to the south) and Romania (north).
In the 1960’s, the government built a massive lock and dam to help control the speed of the river and make navigation safer. The construction of these dams gave the valley of the Danube the nature of a reservoir, and additionally caused a 35 m rise in the water level of the river. The old Orșova, the Danube island of Ada Kaleh and at least five other villages, totaling a population of 17,000, had to make way. People were relocated and the settlements have been lost forever to the Danube.
This huge face is carved into the rocks of the Romanian side of the river to celebrate the Dacian hero Decebalus. He lived in the 1st century AD and was the last king of Dacia, a predecessor country of Romania.
