The con- struction of the west front belongs to the last stages of building the thirteenth-century cathedral. The west front is a monumental screen fitted out with niches for a large number of statues although only a few were put in place during the middle ages. Most of the present statues are nineteenth-century. The central doorway leads directly into the nave, and the doors north and south lead into the side aisles. Above, three tall lancets provide light to the nave while the windows in the gable light the area under the roofs.
