Kale-Krševica is an Ancient Macedonian archaeological site of more than 4 hectares and so far some 1,000 squares have been excavated with a former fortified town in the hills of Krševica overlooking Bujanovac and Vranje, to the south of Ristovac in southern Serbia. It has a history back to the 13th century BC as a settlement with elements of an acropolis, but main preserved characteristics is from the Greek-mediterranean style urban town in the 5th or 4th century BC ( Bronze Age) with stone walls and necropolis. Finds of coins of Philip II, Alexander III, Cassander, Demetrios Poliorketes and Pelagia correspond in general to the chronological span of the archaeological material discovered so far in the course of excavations and may be considered the northernmost Ancient Macedonian city. The Paeonian tribe of Agrianes dwelled in this region, the Scordisci are believed to have razed the town to the ground in 279 BC. The town had at least 3,000 inhabitants in the 4th and 3rd century.
The town had an exceptionally strategic position on a plateau that descends from the Rujan mountain towards the South Morava and Vranje valley. At the slopes of the plateau is a village where houses often have stone blocks from the ancient settlement. Its acropolis and suburbium encompasses 4 hectares extended to the valley of Krševička river.
Dr. Petar Popović from the Institute of Archeology in Belgrade says that the site could be the ancient city of Damastion.
