You don't need to have a strong religious faith to appreciate the serene atmosphere of St. Maria Himmelfahrt Cathedral. Inquire when the next mass starts or when it's open for general viewing.
Located in Altstadt Chur, this principal church is well worth including on your itinerary. But you'll find a great deal more to discover in the area. Chur-Brambuesch Gondola, Rhyetian Railway Building, and Obertor Building are within close reach of St. Maria Himmelfahrt Cathedral.
