Regensburg is a city in Bavaria and its old town is a UNESCO World Heritage Site (since 2006). It lies at the confluence of the rivers Danube and Regen. The first settlements date back all the way to the stone age. The Celtic lived there as well as the Romans. There are lots of great sights in the city, among them the Cathedral and the Stone Bridge which can be seen on the card.
