At first glance, the western façade of the Cathedral has a compositional structure that is independent from the rest of the building, as if it were a fortress and a transversal link to the two towers surrounding it.

Taking a closer look at the imposing and compact profile of the cathedral towers, which dominate the landscape of the city, the original defensive function of the area entrusted to them becomes evident.
