According to legend, the master builder of the Stone Bridge in Regensburg enlisted the help of the devil in the 12th century. What is certain, however, is that the medieval structure was the only fixed Danube crossing between Ulm and Vienna for centuries and was commissioned by wealthy Regensburg merchants and the Bavarian Duke Henry the Proud. Over the centuries, the image of the bridge has changed frequently due to war and natural events. Today, for example, only the southern of what were once three towers remains. As a landmark of the city, the Stone Bridge was one of the reasons that Regensburg was included in the UNESCO World Heritage List.
