The cathedral dates from the 14th and 15th centuries and has an admirable nave and interesting 17th-century retables (altarpieces). Leaving through the south door, you'll find on the left a chapel with the Devost-Christ (Devout Christ), a magnificent woodcarving depicting Jesus contorted with pain and suffering, his head, crowned with thorns, drooping on his chest. Sightseeing visits are discouraged during Sunday Mass.
