It is of particular interest for its slanting columns.

It was built in the 12th century on the outskirts of the city. Interesting elements on the exterior are the small tower on the façade and the sturdy flying buttresses built between the 17th and 18th centuries. It has a basilical floor plan with three naves, separated by composite pillars decorated with plant motifs. It is covered with barrel vaults reinforced by rib arches. The sanctuary of the collegiate church has three apses; the central one is polygonal and the two side ones are semicircular. The interior lighting comes from the side openings and the rose window on the façade. Elements worth noting in the cloister include the decoration on the capitals, made by the workshop of Master Mateo.
