Forges des Salles, Industrial heritage site in Sainte-Brigitte, France.

The Forges des Salles is a former ironworks village spread over 30 hectares in the Forêt de Quénécan, straddling the Morbihan and Côtes-d'Armor border. Its stone buildings stand on a slope: a tall central block with slate roof, dormer windows and a square chimney, flanked by lower wings. The site also holds a 12-metre blast furnace of 1816, workers' housing, a chapel and terraced gardens.

The site was created to exploit the rich iron ore deposits in the region and became one of Brittany's major centers for metal production. It employed hundreds of workers and remained in operation until 1877.

The site displays the daily world of workers through preserved homes, a school, and a chapel that reveal how work and family life were closely connected. Walking through these buildings shows how the community was organized around the forge's rhythms.

The site is best explored on a walking circuit that takes you through all areas of the complex. Wear sturdy shoes since the paths are uneven and some sections are on rough pavement.

The site straddles the Morbihan–Côtes-d'Armor border, fixed by the Revolution along the Pont Lann stream crossed by the footbridge. The village therefore had two post offices, and the Pontavice family pays taxes in both departments and answers to two architects of the Buildings of France.
