Konstanz's cathedral, the Münster, was the center of one of Germany's largest bishoprics until 1827, when the seat was moved to Freiburg. Construction on the cathedral continued from the 10th through the 19th century, resulting in an interesting coexistence of architectural styles: the twin-tower facade is sturdily Romanesque; the elegant and airy chapels along the aisles are full-blown 15th-century Gothic; the complex nave vaulting is Renaissance; and the choir is severely neoclassical. The Mauritius Chapel behind the altar is a 13th-century Gothic structure, 12 feet high, with some of its original vivid coloring and gilding. It's studded with statues of the Apostles and figures depicting the childhood of Jesus. Climb the Münsterturm (Münster Tower) for views over the city and lake.
