A second forge, the Forge Monseu, is located upstream of the Eau Blanche (White Water). This forge built in 1590 by Michel Du Moustier became the property of Joseph de Riquet, Prince of Chimay in 1860. It was also used as a mill during the Second World War.
Integrated research into the ecosystem has been undertaken on the Blaimont site
by the Centre National dEcologie Générale (National Centre for General Ecology) since 1963. The remains of this eco-climatic station are still visible. The Bois de Blaimont plateau is formed by a hard limestone table that dominates and closes off the Vallée de lEau Blanche (White Water Valley) standing 50 m above the level of the river (this limestone comes from old coral reefs formed around 350 million years ago, when the warm seas covered the region). The river must make a large detour southwards to find a fault through which it can flow towards the Vaulx mill. Lovely, tall limestone rocks named "Roches BERLEM" can be admired from the river. The plateau is still haunted by the last beautiful beech trees of the Virelles forest. From the top of the plateau, there are wonderful views of the lake, the Vallée de lEau Blanche (White Water Valley) and the village, towards the viaduct, and eastwards towards Lompret.
