Manoir de la Crasvillerie, Gothic manor house in Réville, France.

Manoir de la Crasvillerie is a granite manor of the 15th–16th centuries, built on an L-shaped plan and much altered over time. On the road side stands a hexagonal tower with a watch room from which the sea could be observed; a smaller polygonal tower rises in the inner angle between the two lodgings, whose separate building campaigns show in the masonry. The windows have stone mullions.

The manor dates from the 15th–16th centuries and may have been built by the corsair François Le Clerc, ennobled in 1551. On 29 March 1555 he hosted Admiral de Coligny there during a tour of the Manche coast. In July 1591 François de La Cour du Tourps burned it in reprisal for attacks on his own manor.

The manor's name comes from the nearby hamlet of Crasville, almost identical in sound. Its hexagonal roadside tower held a watch room from which the sea could be observed, a defensive use tied to the Manche coast. The granite walls and mullioned windows belong to two separate building campaigns, visible where the masonry changes.

The estate sits in the northern part of Réville in a rural setting with clear reference points like the nearby Saint-Martin Church. It is best reached by car, as the location is not served by public transportation.

On 29 March 1555 the manor hosted Admiral Gaspard II de Coligny, touring the Manche coast, with Martin du Bellay, the king's lieutenant general in Normandy, and Gilles de Gouberville. The host was probably the privateer François Le Clerc, ennobled in 1551.
