  The area that is now Austria was settled in pre-Roman times by various Celtic tribes, having been the core of the Hallstatt culture by the 6th century BC. The city of Hallstatt, in fact, has the oldest archaeological evidence of the Celts in Europe.
  
  The Celtic Kingdom of Noricum that included most of modern Austria and parts of modern Slovenia was conquered by the Roman Empire in 16 BC and made a province called Noricum which lasted until 476. The regions of today's Austria which were not located within the province of Noricum were divided between the Roman provinces of Pannonia, which encompassed parts of eastern Austria, and Raetia, which encompassed the areas of present-day Vorarlberg and Tyrol.
  
  Present-day Petronell- Carnuntum in eastern Austria was an important army camp turned capital city in what became known as the Pannonia Superior. Carnuntum was home to 50,000 people for nearly 400 years.
