Les ressources du sous-sol du bassin du Hoyoux jusqu’aux portes de la ville d’Andenne. Un riche passé industriel qui se conjugue au présent

The outcrops made by the incision of the Hoyoux and its tributaries have largely favored the opening of numerous quarries and some mines, in parallel with the installation of various transforming industries. The list of materials exploited is impressive: limestones, dolomites, sandstones and quartzites, conglomerates, clays, sands, iron ores, etc. Their exploitation required an abundant labor force. The quarries were predominantly located in the bottom of the valley, which allowed the establishment of vast and high operating fronts and the extraction of healthy stones, in particular ornamental stones which were declined in different chromatic varieties. Walking today through this popular wooded and bucolic valley, one hardly imagines the industrious activity where resonated the noise of the tools and the labor of the workers.
