Some researchers think that Noreia can be identified with the excavated Celtic-Roman settlement on the Magdalensberg in Carinthia, Austria. Others place it in Zollfeld, Carinthia, or in the area of Liebenfels in the Glan river valley. Another possibility is the area around the Klopeiner See in Carinthia, an area where several graves of Celtic princes have been found.
It is also possible that there is more than one location named Noreia. There seem to be two identical entries in the Tabula Peutingeriana, a 4th century road map. On the map an older Noreia, about 3.5 km in diameter, and a new city of the same name, measuring 7.5 by 3.4 km, can be found in the region of modern Styria.
In the neighborhood of the city in 113 BCE Cimbri and Teutons defeated a Roman army at the Battle of Noreia. It is also not known whether the location of the battle and the capital of Noricum are the same city.
