It has a Latin cross plan, with a nave and two aisles separated by semicircular arches and several side chapels and the altarpieces belong to the Neoclassical-Romantic school.

The tower has a beautiful Madrid-style slate spire that incorporates great verticality into the construction.

In the Santísimo Cristo Chapel there are artworks by Alonso Cano, Luca Giordano and el Greco.

In fact, the painting by El Greco is not to be found in the chapel of the Santísimo, it is situated in the main church but covered by wood.

One of the most curious items on display is a stuffed crocodile, which is said to have been brought over from the Americas during the reign of the Catholic Monarchs.
