Opposite the Rätisches Museum, a stone archway under this tower leads into the court of the strong bishop-princes of Chur, once hosts to Holy Roman emperors—sometimes with whole armies in tow—passing through on their way to Italy or Germany. The bishops were repaid for their hospitality by imperial donations to the people. The thick fortifications of the residence aren't for show: they reflect the tendency of inhabitants to dispute the bishops' powers; by the 15th century those who rebelled could be punished with excommunication.
