The Old Town Hall (Altes Rathaus Bamberg) is a medieval town hall in Bamberg, which is one of the most important and beautiful buildings that characterize the historical center of the city.The Town Hall is a complex of buildings with adjacent bridges and the Ludwig Museum is now located within its walls.he location of the town hall is interesting. It stands on an artificial island in the middle of the Regnitz River, between the former episcopal and working (urban) districts.Legend has it that the Bishop of Bamberg did not give permission to the townspeople to build a town hall, and then the townspeople, by driving wooden piles, erected an artificial island between the two districts, on which the Bamberg Town Hall was erected.A bridge passes through the tower of the town hall. Therefore, the town hall is sometimes called the "Town Hall on the bridge".
