Magnificent estate of 1721 hectares Located north of Lacuisine and west of Chiny, it belongs to the CPAS of the city of Mons, which inherited it in 1887. This sublime estate includes 1,500 hectares of forests and four artificial ponds fed by several streams, including the Tamij-Austria, a tributary of the Semois. The ponds of the Epioux are the last witnesses of the important metallurgical past of our region. Indeed, for more than three centuries, the estate experienced intense metallurgical activity. Since the end of this industrial activity, the only profitable economic activity has been that of forest production. Today, the large forest of the Epioux is a magnificent forest. Several beautiful walks cross the estate.
