The Monastery of San Pedro de Villanueva is a Romanesque monastery previously owned by the order of Benedictines. A church here supposedly was founded by Alfonso I the Catholic, son in law of Pelagius of Asturias. The remaining structures now date from later periods. In the 12th century, the monastery was built adjacent to the church. The buildings underwent substantial rebuilding after the 17th century. In 1835, the monastery was dissolved. In the present century, the monastery has become a national hotel, a Parador. The church is still in use.

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).
