The old Franconian episcopal city and university town of Würzburg, in Bavaria, lies in a beautiful location in a basin in the Main valley. High above the River Main, dominating the scene, stands the medieval Fortress Marienberg, built on the site of a former Bronze Age fort and now one of the town's top points of interest.Intense bombing at the end of WWII left more than 90 percent of the Old Town (Altstadt) destroyed. It has since been painstakingly rebuilt and today offers numerous fine examples of medieval and more contemporary architecture, especially around the historic Market Square (Marktplatz).
