Sobrado Abbey was founded in 952 by Count Hermenegildo Alóitez and his wife Paterna. In 958, the founders transferred the county of Présaras to the monastery and, in that same year, Hermenegildo retired there where he lived as a monk the rest of his life and where he was buried. The abbey was inherited by his descendants and nearly two centuries later, in January 1142, the brothers Fernando and Bermudo Pérez, two of the most distinguished members of the House of Traba, handed it over to the Cistercian monks from Clairvaux.
The abbey flourished during the 12th and 13th centuries and was able to undertake the foundations of its own daughter house, Valdedios Abbey in Asturias. Sobrado was also given the supervision of Monfero Abbey after it joined the Cistercian Order.
After a period of decline, in 1498 Sobrado was the first abbey in Galicia to join the Castilian Cistercian Congregation.
The monumental new Baroque abbey church was dedicated in 1708. Most of the conventual buildings were also rebuilt at this time. The dissolution of the monasteries enforced by the government of Mendizábal in 1835 put an end to the abbey, and the abandoned buildings fell into decay.
In 1954 the Cistercian monks of Viaceli Abbey in Cóbreces, west of Santander, began reconstruction, having already refounded and restored Huerta Abbey in 1929, and were able to resettle the monastery with a new community in 1966.
The present abbey church, now roofed with a number of domes and cupolas, was built at the end of the 17th century, although the Magdalene Chapel (Capela da Madalena or Capilla de la Magdalena) dates from the 14th century. The sacristy was built by Juan de Herrera. The monastery has three cloisters. The kitchen and the chapter house remain of the medieval monastic buildings.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
