It houses one of the best collections of sculpture in all of Europe and possibly the best collection of polychrome wood on the continent. With a collection of more than 3,000 pieces, it stands out for its impeccable catalog of wood carvings from the 13th to the 18th centuries, featuring great universal masters of the genre: Gregorio Fernández, Juan de Juni, Alonso Berruguete, Felipe Bigarny, Pompeo Leoni, Alejo de Vahía, and Pedro de Mena, among many other references.
