Burgos Cathedral

The Abbey of Santa María la Real de Las Huelgas, is a monastery of Cistercian nuns of San Bernardo. It was founded in 1187 by King Alfonso VIII of Castile and his wife Leonor de Plantagenet. It houses works of great value, including some of the oldest stained glass windows in Spain.

Work on this cathedral began in 1158 and was not completed in its current form until the 16th century. It contains several important works of art from the Hispano - Flemish style, as well as unique metalworks.

The Monasteries of San Millán de la Cogolla are a complex of two monasteries founded in the 6th (San Millán de Suso) and 11th centuries (San Millán de Yuso). The monasteries have changed owners many times (Visigoths, Spaniards, Muslims) and now bear their marks such as the Mozarabic arches inside the Suso building. Both buildings have been listed as UNESCO World Heritage Sites since 1997.
