Golubac Fortress (Serbian: Голубачки град or Golubački grad, Hungarian: Galambóc vára, Bulgarian: Гълъбец, Romanian: Cetatea Golubăț, Turkish: Güvercinlik Kalesi) was a medieval fortified town on the south side of the Danube River, 4 km downstream from the modern-day town of Golubac, Serbia. The fortress, which was most likely built during the 14th century, is split into three compounds which were built in stages.
