La galerie minière de la Chartreuse à Liège (Belgique) : un « cas d'école »

The mining gallery at « La Chartreuse » in Liege presents an interesting underground environment from different points of view. Especially, its varied fauna, including some cavernicolous species, offers a particular interest. In agreement with the local authorities, training courses in Biospeology have been organized at this site by the Belgian School of Speleology for the past several years.
