Former metal processing plant

In 1806, on the death of the widow of Joseph-Alexis Poulain, owner of all the metallurgical establishments in Boutancourt, the Forge du Bas included a platinum works and a forge. This establishment complemented the two upper factories in Boutancourt. When Jean-Nicolas Gendarme bought it from Poulain's son-in-law in 1821, the forge consisted of a large hammer, two foxholes and two turntables. When Gendarme died in 1845, the Boutancourt works passed to his grandson Hannonet de la Grange and, in 1865, to Société E. Muaux et Cie, which also owned the Flize factory (IA08000397). The site has now been converted to residential use. The factory consisted of three parallel buildings located close to the dyke of the reservoir: the forge hall (destroyed), the turntable and coal shed, and the workers' accommodation. The remaining buildings are reminiscent of those at the Forge du Haut. They are built of limestone rubble and ashlar for the frames, and have long-sloped roofs with half-hipped roofs and exposed wooden frames covered with mechanical tiles.
