Noricum is the Latin name for a Celtic kingdom, or federation of tribes, that included most of modern Austria and part of Slovenia. In the first century C.E. it became a province of the Roman Empire. Its borders were the Danube to the north, Raetia and Vindelicia to the west, Pannonia to the east and southeast, and Italia (Venetia et Histria) to the south. The kingdom was founded ca. 400 BC, and had its capital at the royal residence at Virunum on the Magdalensberg.
