Chur is an Alpine city and the capital of the Graub├╝nden canton in eastern Switzerland. Winding streets in the car-free old town lead to the 13th-century, three-naved Cathedral of the Assumption, in the courtyard of the Bishop's Palace. The Brambr├╝esch aerial cableway ascends to a plateau with trails, panoramic views and winter ski slopes. From Chur, the Bernina Express train crosses the Alps into Italy.
