Aguntum

The ruins of Aguntum are Roman site in East Tirol, Austria, located approximately 4 km east of Lienz in the Drau valley. The city appears to have been built to exploit the local sources of iron, copper, zinc and gold. During the early Christian era the city was the site of a bishopric, which, having ceased to be a residential diocese, is today listed by the Catholic Church as a titular see.
