The temple has an asymmetrical layout and was built in different stages.
It has two naves, the first from the 13th century, a second nave was built to the north of the first at the end of the 15th century and at the beginning of the 16th century, an extension to the south gave the temple a Plateresque façade protected by a portico. On both sides of the façade, two chapels were opened, also at the beginning of the 16th century. A last chapel was opened at the northeastern end of the temple, in the 17th century, in the Renaissance style.At the foot of the old nave there is a tower built over the street and incorporated into the old choir staircase, with three bodies and crowned by a balustrade. The ground floor of this tower has a gap leading to the street under a semicircular arch topped by a split triangular pediment. This passage is called the Arco de la Villa.
