Château de la Desnerie, Historical monument in La Chapelle-sur-Erdre, France.

The Château de la Desnerie is a long, low building in La Chapelle-sur-Erdre with pale cream walls and a steep dark grey slate roof. Its symmetrical facade centres on a projecting section topped by a rounded pediment, with three levels of windows, pale shutters and small dormers. Tall red-brick chimneys rise from the roofline, and a short stair sits at the centre base.

The estate was owned by Jean Leet, a companion of Du Guesclin, in 1371 and later passed to several noble families including La Roche-Saint-André and Sesmaisons. This succession of owners shaped how the castle developed physically over the centuries.

The west wing, designed by architect Jean-Baptiste Ceineray in the 18th century, shows how French noble residences evolved over time. The chapel with its altarpiece remains part of this architectural development that connects different periods together.

The château is private property in La Chapelle-sur-Erdre, in the Loire-Atlantique department. It stands at coordinates 47.27270, -1.53533, and visits must be arranged in advance with the owners. The west wing added by the Trévelec family is the part to look for from outside.

The 1985 listing as a monument historique protects the chapel with its altarpiece and the 18th-century salon, so the designation covers interior furnishings as well as the building itself. The west wing was added for the Trévelec family by architect Jean-Baptiste Ceineray.
