It was built in the Gothic style between 1250 and 1312. It has three naves –of which the central nave is wider than the side naves– chapels between the buttresses, and a polygonal sanctuary. It is covered with a simple cross vault. Highlights on the inside include the triforium, a corridor which runs the length of the church formed by elegant and intricate tracery. The tower and the doorway are in the Renaissance style. Elements from the 17th and 18th centuries are the high altar dedicated to Santa María, the ambulatory and its chapels, the sacristy, the chapter room and the chapel of San Juan del Ramo. This chapel has a vault decorated with tempera painting by Luis Paret y Alcázar.
