Surrounded by Franconian vineyards, Würzburg was heavily damaged during World War II, but has since been completely restored. Here is Germany’s most pristine example of baroque architecture, the great Residenz, built in 1744 by the Prinz-Bishops. Its sweeping staircase and amazing ceiling frescos by Tiepolo survived wartime bombs. Other landmarks include the medieval statue-lined Main Bridge and Marienberg fortress, originally a Celtic hill fort and later residence of the bishops. The round 8th-century church within the courtyard of the fortress is one of Germany’s oldest churches.
