The Square designed in the mid-nineteenth century, it has undergone several renovations, most recently in 2000. It highlights the monumental facade of the cathedral fortress which presides from the sixteenth century, with its Renaissance main entrance.
The commencment of the building of the Cathedral was in 1524, after the earthquake in 1522 destroyed the first, which was located in the Medina, on the site of the old mosque. Its main feature was to be cathedral-fortress, because it was built for both religious worship and to shelter the population from attacks by Barbary pirates. This is seen in its main facade: use of large buttresses and towers at the corners, solid walls and concentrated decoration on its main entrance, where campean the shield of Carlos I of Spain and V of Germany, and the Bishop founder of the cathedral, Fray Diego Fernandez de Villalán. The side of the street Velázquez, and so-called “pardons” the door is the same as the main one, although simpler Renaissance style decor.
