The museum's finest exhibits include the coro, a masterpiece of Romanesque art representing New Jerusalem, a gilded monstrance by Antonio de Arfe (1539-1566), and the remarkable tapestries designed according to the cartoons of Goya, Bayeu, Rubens and Teniers. The entrance ticket also includes access to the vast cloister (early 16C) which combines a Gothic structure with a Plateresque decor, the Palacio de Gelmírez, with its medieval kitchen and synod hall, and the crypt of the Pórtico de la Gloria, built in the 11C.
