This church was the result of late Romanesque architecture, presents a three-nave structure and an apse modified in the baroque period. The arcade and the tower, declared National Monument in 1896, were added in the 13th century. The tower is considered one of the most beautiful among the Romanesque ones. After suffering a fire in 1896, it was dismembered and rebuilt in the early 20th century, replacing its baroque slate roof with a tiled one. All these difficulties did not lessen the elegance of the tower, an unmistakable milestone in the silhouette of the city.
