The cathedral was consecrated by Pope Gelasius II in 1118 and was built between the twelfth century and the fourteenth century as fundamentally a medieval building, with some later additions. Secondary naves and side covers are of Romanesque style and the main facade is Gothic from the early thirteenth century, while capitals and columns with interior corridors date from the early fourteenth century. The bell tower and dome were built in the sixteenth century.
