Former metal processing plant

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 winnowing system still remain. Today, the premises are shared between the Aplitec factory, which specialises in metal processing, and a small-scale roofer.

The complex comprises buildings dating from the early 20th century, with a seven-bay production workshop with tiled and glass sheds, and a dwelling house with a slate roof. The supporting structures are metal with cast-iron posts. Later extensions were added, notably between the wars and in the 1950s, with a turbine building and an extension to the south. The old buildings are of limestone rubble, while the extensions are of iron pan and concrete. A hydraulic turbine is still present on the site to the east.
