Golubac Fortress is a medieval fortification built in the fourteenth century, located on the right bank of the Danube, in its gorge near the Iron Gates. The fortification is situated at the border between Serbia and Romania, in the Braničevo district, and is part of the Đerdap National Park. Partially submerged due to the construction of the Iron Gates dam, the fortress is recognized as a monument of exceptional importance to the Republic of Serbia.
