The Hisar, is a hill near Leskovac and Prokuplje, Serbia which is the town's symbol. As the word "hisar" derives from Turkish and means "fortress", it is the site of the medieval fortress with a still well preserved tower, popularly called the Tower of Jug Bogdan, who was a hero of the Battle of Kosovo.
Hisar is a multi-periodal settlement.
Traces of life of the Brnjica culture (8th century BC) is seen in the plateau that was protected by a deep moat with a palisade on its inner side, a fortification similar to that of another fortification on the Gradac site in Lanište in the Velika Morava basin.
