The present cathedral is a combination of two buildings, and possesses two apses. The apse and transept at the west end are the remains of a Romanesque church, while the nave and eastern apse are in the Gothic style and belong to the 14th century. There is no transept at the eastern end. The lateral portal on the south side belongs to the late 15th century; the massive and elaborately decorated tower which rises beside it to the early 16th century. It has been destroyed 2 times before, and later on fixed.
