Bamberg is a town in Upper Franconia, Germany, on the river Regnitz close to its confluence with the river Main. The town dates back to the 9th century, when its name was derived from the nearby Babenberch castle. Cited as one of Germany's most beautiful towns, its old town has been a UNESCO World Heritage Site since 1993, with Bamberg being home to Europe's largest intact old city wall.
From the 10th century onwards, Bamberg became a key link with the Slav peoples, notably those of Poland and Pomerania. It experienced a period of great prosperity from the 12th century onwards, during which time it was briefly the centre of the Holy Roman Empire. Emperor Henry II was also buried in the old town, alongside his wife Kunigunde. The town's architecture from this period strongly influenced that in Northern Germany and Hungary. From the middle of the 13th century onwards, the bishops were princes of the Empire and ruled Bamberg, overseeing the construction of monumental buildings.
