The dovecote, which survived the post-Revolution demolition, is one of the largest in the region.
The site was once home to an extensive fish farming network that provided food for the monks.

Archaeological excavations have uncovered evidence of the original Romanesque layout beneath later additions.
The Abbaye de Mortemer is a Cistercian monastery founded in 1134 by Henry I of England, located in the heart of the Lyons Forest in Normandy. Following the French Revolution, the abbey was largely dismantled, leaving significant ruins including the 12th-century crypt and parts of the dovecote. The site remains privately owned and is surrounded by an extensive park containing a lake and a woodland trail. The remaining ruins are protected as a designated historic monument. Visitors can explore the remnants of the abbey buildings and the grounds which are associated with local folklore regarding the 'White Lady'.
