Magdalensberg in the context of Klagenfurt-Land

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

Claudium Virunum was a Roman city in the province of Noricum, on today's Zollfeld in the Austrian State of Carinthia. Virunum may also have been the name of the older Celtic-Roman settlement on the hilltop of Magdalensberg nearby.Virunum (Virunensis) is today a Catholic titular see.
