Santa María de La Vid is a monastery in Spain's Duero Valley was founded on a different site, a place called Montesacro, in about 1146 by Domingo Gómez, illegitimate son of Queen Urraca of León and Castile and her lover Count Gómez González de Candespina. Domingo had become interested in the Praemonstratensian order on a visit to France, and this was the first Praemonstratensian house in Spain.
The monastery was moved to its present site in 1152, having been given the estate of La Vid by Alfonso VII of León and Castile, who was the half-brother of Domingo Gómez. It was closed as a result of the ecclesiastical confiscations of Mendizábal in the 1830s. It was re-opened in the 1860s by the Augustinians who still inhabit it.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
