Château de Bois-Briand, 17th-century château in Nantes, France.

Château de Bois-Briand stands in Nantes on the right bank of the Aubinière, near Sainte-Luce-sur-Loire. Its main lodge combines a medieval section with a half-projecting stair tower, a corner turret and granite openings, a 17th-century east facade, and an 18th-century orangerie. The pale stone building has a steep dark grey roof with three white-framed dormer windows, and dense climbing plants cover much of the facade.

The Le Meneust des Treilles family purchased the land in 1699 from the Charette family and built the manor as it stands today. This transition marked the shift from a medieval fortified site to a residential property focused on agricultural production.

The name Bois-Briant, also written Bois-Brient, refers to a wood facing south that shines in the sun; the road to the château kept the spelling Avenue de Bois-Briant until 1990. In the Nantes region such pleasure houses were called "Folies", and the estate combined leisure with wine and dried fruit produced for sailors.

The private estate covers about 1.5 hectares, while the monumental ensemble and planted grounds extend over roughly 10 hectares. The main house stands on the right bank of the Aubinière, under 300 m from the church of Sainte-Luce-sur-Loire. The water mirror, a 100 m canal, closes the square French garden east of the house.

The name Bois-Briant, also written Bois-Brient until the early 20th century, describes a wood facing south that "shines" in the sun. The road leading to the estate kept the older spelling as Avenue de Bois-Briant until it became rue du Bois-Briand in 1990.
