Revitalization of Golubac Fortress

Golubac Fortress was a medieval fortified town on the south side of the Danube River, 4 km downstream from the modern-day town of Golubac, Serbia. Golubac consists of three main compounds guarded by 10 towers and 2 portcullises, all connected by fortress walls 2–3 meters thick. In front of the fortress, the forward wall doubled as the outer wall of the moat, which connected to the Danube and was likely filled with water.
