Dinkelsbühl’s old town was founded by Carolingian kings as early as the 8th century and served as a royal residence for a long time. Since the town centre remained almost undestroyed in both the Thirty Years’ War and the Second World War, it was possible to preserve the authentic image of the old town here. In order to preserve this historic appearance, house owners are subject to strict regulations: façade colours may only be chosen from a predefined colour palette, advertising space is not permitted and all signs are designed in old German script. Sights include the octagonal lion fountain from the 16th century, the House of History, the well-preserved town wall and the Rothenburg pond.
