Blockhaus not far from the French-Belgian border, opposite Belgium. This is located approximately halfway between two large French bunkers on a SW-NE line, west of the A2 motorway. This French blockhouse, Réservoir d'Onnaing, is a so-called Poste de Tir. The entrance is 20m away and gives access to the shooting room through a short tunnel.
