Monastery of San Pedro de Arlanza

San Pedro de Arlanza is a ruined Benedictine monastery in north central Spain.

It was abandoned in 1841 during the confiscations of Juan Álvarez Mendizábal's government, when ecclesiastical properties were roundly redistributed.

San Pedro's two purported founding documents, preserved in twelfth-century cartulary, were issued one by Count Fernán González and his wife, Sancha of Navarre, and the other by Fernán's mother and brother, Muniadona Ramírez and Ramiro González, with Count Gonzalo Téllez and his wife, Flamula.

Among the ruins the three apses still stand, as do the tower (erected towards the close of the twelfth century), part of the cloisters and the chapter house, and the double-aperture and the tympanum above the main façade.

A large Romanesque tomb, said to belong to the legendary Mudarra González, was moved to the Cathedral of Burgos, and some frescoes have been transferred to the Metropolitan Museum of Art in New York[2] and others (like Paintings from Arlanza) to the Museu Nacional d'Art de Catalunya in Barcelona.
