San Pedro de Arlanza is a ruined Benedictine monastery located in the valley of the river Arlanza in Hortigüela, Burgos. Founded in 912, it has been called the 'cradle of Castile' (cuna de Castilla). It was abandoned in 1841 during the confiscations the government of Juan Álvarez Mendizábal, 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, and the other by Fernán's mother and brother, Muniadona Ramírez and Ramiro González, with Count Gonzalo Téllez and his wife, Flamula. Both documents suffer from certain inconsistencies and anachronisms that have cast doubts on their authenticity, especially that of Fernán González. It was probably forged to give the monastery a more illustrious lineage than it could prove to have. The copy of the charter of Gonzalo Téllez is more likely to be based on reality, since Gonzalo is known to have been active in 912. Fernán González and Sancha were buried at San Pedro, however, and remained there until the dispersal of the monastic community in 1841 necessitated the removal of their sarcophagi to the collegiate church of San Cosme y San Damián at Covarrubias.
The present ruins of the church are those of the building begun in 1080. It had three naves and three semicircular apses in the Romanesque style. Later modifications in the Gothic style transformed the outward appearance, but some of its eleventh-century capitals have been preserved. 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. The portal of the church was transferred to the National Archaeological Museum of Spain in Madrid in 1895. 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 and others (like Paintings from Arlanza) to the Museu Nacional d'Art de Catalunya in Barcelona.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
