This Gothic-Mudéjar church, built between 1380 and 1550, is in many ways even more impressive than El Pilar. The rich facade is a fine example of the Aragonese Mudéjar style and the structure is an exemplar of Aragonese Gothic architecture. Among its more important features are the main altar and a fine collection of French and Flemish tapestries from the 15th to the 17th centuries, which are housed in the adjacent museum.
