Carnuntum

Carnuntum was a significant Roman site located on the Danube River in Lower Austria. Initially established as a military base during the reign of Augustus, it grew into a major Roman city and capital of the Pannonia Superior province. It was a vital hub for military and trade activities, particularly in the amber trade. The city reached its zenith during the Severan dynasty, notable for its economic prosperity and elevation to colony status. Key features included a legionary fortress, civilian city, amphitheatre, and the Heidentor monument. Despite its prominence, Carnuntum suffered severe earthquake damage around 350 CE and was eventually destroyed by Germanic invaders in 374 CE, leading to its decline and abandonment.
