Church of San Andrés

The Collegiate Church of Santa María la Mayor was built from 1120 on a former mosque. The current temple dates from the early 17th century. The tower is one of the main examples of the Aragonese Mudejar style. It has an octagonal plan and buttresses on the edges. The slate spire dates from about 1770 and the bell bodies date from the 17th and 15th centuries.

The church was built after the battle of Cutanda (1120), when, at the entrance of King Alfonso I the Battler to Calatayud, a contingent of Franks from Bigorra under the command of the Count of Alperche, who had supported the king in the Reconquest.

Located next to the old Puerta de Somajas, currently called Puerta de Zaragoza, the current Royal Basilica-Collegiate Church of the Holy Sepulcher was completed in 1613 by the architect Gaspar de Villaverde, who erected a proto-baroque temple of Herrerian tradition on the previous one of Mudejar style, of the that some remains are still preserved.
