Like a ship in dry dock, Bamberg's 1462 Old Town Hall was built on an artifical island in the Regnitz River, allegedly because the local bishop had refused to give the town's citizens any land for its construction. Inside you'll find the Sammlung Ludwig, a collection of precious porcelain, but even more enchanting are the richly detailed frescos adorning its facades – note the cherub's leg cheekily protruding from the eastern facade.
