The Cathedral is a white-painted monumental church with one high belltower to the right of the main entrance. It was built on a plan that has three longitudinal naves with semi-ogival arches on square pillars. The Cathedral is built like the kind of the 16th century. Based on interior features — like the details of the pillars, arches, and the carved and coffered ceiling — some experts say that the Cathedral should be thought of as Gothic-Mudéjar in style. It has Gothic features in the pointed arches of its naves, as well as in the ambulatory that goes around the presbytery.
