Around 2000 years ago one of the most important metropolises in the Roman Empire was founded. In the year 6 AD Tiberius, who later became emperor, erected a fortified winter camp in the Carnuntum area. In the following centuries Carnuntum, as the capital of the province of Upper Pannonia, was often in the limelight of world politics. In its heyday the city covered about 10 sq. kilometres, had about 50,000 inhabitants and was the base of the Roman Danube fleet. After its prime, Carnuntum slumbered for more than 1500 years, until the enthusiasm of archaeologists rescued the former metropolis from the mysteries of the past.
