Ancienne usine de transformation des métaux

In 1835, Camion-Richard built a factory in Vrigne-aux-Bois, comprising a refinery, forge and rolling mill, powered by three waterwheels on the Jacquemotte pond. The reservoir and sluice system still remain. Today, the premises are shared between the Aplitec factory, which specializes in metal processing, and an artisan roofer. The complex comprises buildings dating from the early 20th century, with a seven-bay shedshed manufacturing workshop covered in tiles and glass, and a slate-roofed dwelling house. The load-bearing structures are metal with cast-iron posts. Later extensions were added, notably between the wars or in the 1950s, with a turbine building and an extension to the south. The older buildings are of limestone rubble, while the extensions are of pan de fer and concrete. A hydraulic turbine is still present on the site to the east.
