The exploitation of the Opprebais quarry began during the construction of the Namur-Louvain road around 1755, under the impetus of Empress Maria Theresa of Austria: quartzite was extracted there, a very hard stone mainly used for making paving stones but still present in its natural state in certain areas of the municipality. Some parts of the Opprebais castle-farm are built with quartzite rubble stones. Production stopped for the first time and, in 1935, the quarry was flooded. Activity resumed from 1958 to 1975. The lake, fed by groundwater, is surrounded by rock faces and vegetation. Owned by the Société Wallonne Des Eaux, the quarry is closed to the public: access to the water and swimming are prohibited: the site had to be fenced off to prevent any intrusion as the place is dangerous due to its depth (up to 30m), the water temperature (risk of thermal shock) and the presence of rocks. The place is also known to diving clubs. A path, enhanced by a fitness trail, allows you to walk around it.
