Château de Couffour, Medieval castle ruin in Chaudes-Aigues, France.

Château de Couffour is a medieval castle ruin featuring a circular tower containing three upper floors with small rooms connected by a spiral staircase in a western turret. The ground floor has a square layout with ribbed vaulting, creating a contrast with the round design above.

Couffour is attested from the 12th century, when Blavia, descendant of Robert de Saint-Urcize, brought the land as a dowry to Falcon de Reveilhac, founder of the seigneury. The castle was a stronghold during the Hundred Years' War. In 1406 Antoine de Rochedragon bought it from Jean Besse. Sold to a local bourgeois in the 18th century, it declined after the Revolution; the tower was listed as a monument historique on 17 September 1969.

On the first floor, one room keeps 17th-century wall paintings: bouquets of leaves and flowers framing portraits of women and landscapes in rectangular panels. The same room has an 18th-century painted wooden fireplace. The name Couffour comes from the land brought as dowry by Blavia, descendant of Robert de Saint-Urcize, to Falcon de Reveilhac.

The castle operates as a hotel-restaurant with two Michelin stars managed by Serge Vieira, a winner of the 2005 Bocuse d'Or. Visitors can explore the historic rooms while enjoying contemporary dining offerings available on site.

The castle passed to the commune of Chaudes-Aigues, which still owns it, and the tower was inscribed as a monument historique on 17 September 1969. Since 2009 the site has housed a two-star Michelin hotel-restaurant run by Serge Vieira, Bocuse d'Or 2005.
