During the visit you'll be able to climb the 157 steps of the towers leading to the top of the Cathedral. You will also discover magnificent architectural treasures - an emblematic symbol of the Reformation. In addition, the Cathedral holds the largest collection of Romanesque and Gothic capitals in Switzerland, while the stained-glass windows, identical to the Renaissance examples found in the Musée d'Art et d'Histoire (Museum of Art and History) date back to the 19th century. A real gem.
