Château de Belval, Heritage castle in Le Saulcy, France.

The château de Belval is a neo-Renaissance castle completed in 1904 on the territory of Le Saulcy, facing the neighbouring commune of Belval. It was built for Louis-François Nansé and his wife Marie Julie Louis, textile industrialists who settled in this Vosges valley after the 1870 war. Its slate roofs differ from the original ones, which were altered after a fire of unknown date.

The estate was built in 1904 by wealthy textile entrepreneurs and symbolized their economic rise. During World War II, the building was occupied by authorities and used as a detention facility, a period that deeply marked its history.

The castle takes its name from the neighbouring commune of Belval, not from Le Saulcy where it stands, because it faces Belval and the road leading there. Numbered pyramid-shaped boundary stones marked with an "N" for Nansé still line the valley slope opposite the castle, marking land the family bought in Belval.

The château stands on the Le Saulcy side of the valley, facing Belval and the road that leads there; the numbered pyramidal boundary stones marked with an "N" on the opposite slope trace the Nansé family's land purchases. The textile works that once flanked the building to the east were demolished and replaced by meadows, so little remains of the industrial setting. The site was long managed by the Caisse Régionale d'Assurance Maladie du Nord-Est, which ended its holiday stays in 2006.

The castle's name comes from the neighbouring commune of Belval, not from Le Saulcy where it stands: it faces Belval's land and the road leading there, and the Nansé family owned plots on that side. Numbered pyramid-shaped boundary stones marked with an "N" still line the valley slope facing the castle.
