The Roman settlement Carnuntum

Carnuntum was the name of the most important Roman settlement in Austria, located about halfway between Vienna and Bratislava in Slovakia. It was a legion camp, auxiliary fort and became even a civil city. The oldest archaeological evidence dates from the middle of the 1st century CE, but the name has been known since 6 CE. From approx. 50 d.Z. it became the headquarters of the Pannonian Danube fleet. As a civil city, it became the capital of the province of Pannonia under Emperor Traian in the early 2nd century. In its heyday, the city had around 50,000 inhabitants. Around 350 an earthquake caused great damage, and that may have started the decline of the city.
