Kostolac is a small Serbian town on the Danube River. In a 2002 census, Kostolac’s population was recorded as 9,313—6,912 Serbs, 1,756 Roma and 645 “others.” It is located where the ancient Roman outpost of Viminacium used to be. Destroyed by Huns in 440 A.D., rebuilt by Justinian I, then destroyed again by Avars in 584, the ruins of Viminacium, with their wide streets, spacious homes and public baths, are now open to visitors.
