This transitional Gothic-style cathedral built in the late 12C and 13C has certain Romanesque features. Its austere pink-granite façade is flanked by two robust towers with conical steeples, erected in the 16C. The interior contains a beautiful dome on squinches that covers the transept crossing, and beautiful oak stalls dating from the Renaissance. A Gothic cloister and a sacred art museum boasting a fine collection of religious silver work, round off the visit.
