Château de Nescus, Neoclassical château in Nescus, Ariège, France

Château de Nescus is a neoclassical building of about 1,400 m² standing at 426 m altitude east of the village, across the Arize from the hamlet of Ballé. Its facade carries both a round and a square tower, each crenellated, and a 2.2-hectare wooded park surrounds it. The pale walls have arched ground-floor windows and a taller central section with small upper windows.

Built in 1700, the château was demolished during the Revolution and rebuilt in the 19th century. A fire in 1918 required renovation. It belonged to Albéric de Narbonne-Lara (1859–1909), then to the Carmelites of Pamiers, before the city of Paris acquired it for its holiday colonies.

The château's name comes from the commune of Nescus in the Ariège. After the Paris municipality bought it for its holiday colonies, it later passed through private hands; in October 2022 it was auctioned and acquired for €118,000. The planned project combines tourist accommodation, a visitable landscaped garden with market gardening, cultural events and social housing.

The château stands at 426 m altitude east of the village and south of the hamlet of Le Ballé, from which it is separated by the Arize river; it is reached from the RD 15. The building has been unused for over a decade and was damaged after a squat, so the grounds are not set up for visitors.

The château was bought at auction in October 2022 for €118,000, after more than a decade unused and damaged by a squat. The buyer's stated aim was a project integrated into the territory and its environment. The building has about 1,400 m² of floor space and stands at 426 m altitude.
