Sobrado Abbey, (Spanish: Monasterio de Santa María de Sobrado de los Monjes or Galician: Mosteiro de Santa María de Sobrado dos Monxes) is a Cistercian monastery in the province of La Coruña, Galicia, Spain. It is situated in the municipality of Sobrado, about 9 km east of Corredoiras and about 46 km southeast of Betanzos, at an altitude of 540 m above sea level.
The 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.
