In the 15th century, reconstruction was begun on top of the foundations of the original 14th century church. It was extended in the 16th century and finished in the 17th century. From the Gothic period, the church conserves the facade, the side chapels, the cloister, and a small part of the triforium. Between 1575 and 1629 the church was augmented in a traditional renaissance style. This work coincided with the defeat of the Invincible Navy (1588), a fact that led to the decline of the wool trade and, consequently, the delay in the augmentation of the church.
