Claudium Virunum was a Roman city in the province of Noricum, on today's Zollfeld in the Austrian State of Carinthia. Virunum was founded under Emperor Claudius as the capital of the province of Noricum. The new Roman foundation was situated on the main route from the Adriatic to the Danube, with a branch through south eastern Carinthia connecting Virunum with the Amber Road.
From AD 343 Virunum is known to have been a bishop's see. Little is known about the decline of the city. Being unfortified and situated in a flat valley, during the Migration Period the city was probably partly or totally evacuated by its inhabitants, who left for the surrounding hills such as Ulrichsberg or Grazerkogel.
The city proper covered an area of about 1 km². Extensive and systematic excavations took place from end of the 19th century until 1931. Further excavations were not undertaken until the end of the 20th century culminating in the excavation of the amphitheatre.
Apart from the city capitol, a Dolichenum for the military god Jupiter Dolichenus was excavated, inscriptions have been discovered proving the existence of two Mithraea, and in 1999 two votive relief plates were found from a Nemesis temple near the amphitheatre. Proof of an early Christian church, whose existence had been presumed for a long time, has recently been found in the northern section of the city.
A proper Roman theatre with a stage, the only one known in all Noricum, as well as elliptic amphitheatre were situated on the slope of Töltschach Hill. A large building further east is believed to have been the palace of the Praeses or provincial governor.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
