The stained glass windows of the cathedral are considered the most valuable in Switzerland. The windows date from 1441-1460. The most interesting window is the "Dance of Death" window located at the top of the right side nave.

The minster, dedicated to St Vincent (originally the parish church, later made collegiate), was planned by Matthäus Ensinger from 1421 to replace a 12th century predecessor. It was largely completed by about 1540 by successive architects, including Vincenz Ensinger and Erhard Küng. The upper part of the tower was finished only in 1889-1893. It is an aisled, Late Gothic basilica with a richly sculpted portal of the Last Judgment by Küng, interior statuary (1517), important stained glass (1441-1460) and choir-stalls (1522), and is the outstanding Late Gothic building in Switzerland.
