The Capitol Hall, some of the monastery's cells, and the lavish Hall of the Kings host the Museum, which is a treasure of art that amply demonstrates the building's richness and the aristocratic origin of many nuns: reliquaries, furniture, large tapestries, sculptures, and paintings by the great artists of the 1500s and 1600s, including Titian and Zurbarán. You should also look at the refined Baroque chapel with its frescoes and sculptures.
