Roman towns and cities in Slovenia

Emona (early ) or Aemona (short for ) was a Roman castrum, located in the area where the navigable Nauportus River came closest to Castle Hill, serving the trade between the city's settlers – colonists from the northern part of Roman Italy – and the rest of the empire. Emona was the region's easternmost city, although it was assumed formerly that it was part of the Pannonia or Illyricum, but archaeological findings from 2008 proved otherwise.
