Since the beginning of research on the crossed spur of Pont-de-Bonne (Modave, Belgium), we have uncovered artefacts attributed to the Middle Neolithic. More recently, during excavation of the entrance system of the fortification, a pot hole and a waste accumulation zone have been analyzed. These features contained abundant archaeological material (ceramic sherd, lithic and bone artefact aswell as fauna). Three radiometric dates have been obtained. The ceramic assemblage is typical of the Belgian Michelsberg and a decorated vase shows Bischheim affinities.
