Charbonnage du Renard, this location used to be a part of a coal mine. After the mine was closed, al that was left was this site. But was this site always a garage? Or did it became a garage after the mine? Can't find anything about that on internet. Renard is the surname of an architect born in Belgium a long time a go. Mister Renard also designed coal mine. But I'm not sure if this has anything to do with this place.
