Dom Mariä Heimsuchung

North of Rathausplatz you'll find the cathedral, Dom Mariä Heimsuchung, which dates back to the 10th century. Architecturally it's a hotchpotch of addition on addition, including the instalment of bronze doors in the 14th century depicting Old Testament scenes. The oldest section is the crypt underneath the west choir, which features a Romanesque Madonna. Other treasures include medieval frescoes, the Weingartner Altar by Hans Holbein the Elder, and - dating from the 12th century - the Prophets' Windows (depicting Daniel, Jonah, Hosea and Moses), some of the oldest stained-glass windows in Germany.
