The Monastery of Santa María la Real de Las Huelgas is one of the most important Cistercian foundations in Spain, still inhabited by a community of Cistercian nuns and housing the royal pantheon of medieval Castile. Founded by Alfonso VIII and his wife Eleanor of England (daughter of Henry II and Eleanor of Aquitaine), it was the most powerful convent in Spain for centuries — the abbess had the authority to hear confessions, a power normally reserved for priests.
The museum inside the monastery complex displays the extraordinary textiles found in the royal tombs: brocaded silks, embroidered cloaks, and a military standard captured from the Almohad army at the Battle of Las Navas de Tolosa in 1212. The museum also holds the articulated effigy of Alfonso VIII, one of the finest Romanesque royal portraits in Europe. Guided visits only; about €6. Located about twenty minutes' walk west of the cathedral.
