The original 14th-century edifice had a single nave with four bays with vaults and flying buttresses, with chapels, ending with a transept and a pentagonal apse.

In 1343 a Mudéjar tower was added, originally near the entrance, but now enclosed in the main body of the building.

The tower has an octagonal plan, and, like the church, is made in brickwork, part of which are decorated.

The lower section is not visible from the exterior, as it is currently embedded within the church: it has an Arab-style frieze.

The reredos (retablo) of the main altar, in gilded and polychrome wood, was executed by Damián Forment (1515–1518).
