The monastery was originally established as a Benedictine house before affiliating with the Cistercian Order in 1177.
Much of the current structure was salvaged and reconstructed using original stone blocks that were relocated from the ruins of the original site after the 19th-century abandonment.
The architectural transition from Romanesque to Gothic is clearly visible in the pointed arches of the main nave.
It is frequently referred to as the 'Monasterio de Pelayos' due to its proximity to the town of Pelayos de la Presa.
The monastery underwent significant private restoration efforts in the 21st century to rescue the site from total collapse.
The Monasterio Santa María la Real de Valdeiglesias is the oldest Cistercian monastery in the Madrid region, dating back to its original foundation in the 12th century. The site consists of a complex mix of Romanesque and Gothic architectural elements, reflecting centuries of modifications. Abandoned during the 19th-century Mendizábal secularization, the monastery fell into severe disrepair before being declared a site of cultural interest. Today, the ruins feature preserved vaulted ceilings, cloisters, and stone carvings that demonstrate the austerity typical of the Cistercian order. The private owners have conducted structural stabilization and restoration work to preserve the remaining masonry and architectural layout. The site remains a unique example of medieval monastic architecture in the Sierra Oeste area.
