Construction started on the site of the former Romanesque cathedral on July 20, 1221, beginning at the chevet, which was completed in nine years.
To je edina španska katedrala, ki je na seznamu samostojno, ne da bi se pridružila zgodovinskemu središču mesta (kot v Salamanci, Santiago de Compostela, Ávila, Córdoba, Toledo, Alcalá de Henares ali Cuenca) ali z drugimi objekti, kot v Sevilji.
