Built on the ancient Moorish mosque, it was initially built as a parish church, and went on to become used by archpriests (1281), as a school (1413) before eventually becoming the cathedral (1510).
On the outside we can see the tower which was built somewhere between the end of the XIII century and the start of the XIV century. There are also three main doorways: the XIV century Door of Chains (la Puerta de las Cadenas), the XV century. The door of Loreto (la Puerta de Loreto) and the Door of the Annunciation (la Portada de la Anunciación), which was finished by Juan Inglés in 1558.
