The Carrière des Peupliers in Abscon is a former chalk and marl quarry used to produce lime for the USINOR factory in Denain. These industrial activities have significantly changed the landscape of the Denaisis plain. After the end of the industrial activities, the land was transferred to the Nord department. Today, the area is an interesting place for nature lovers and offers a unique insight into the industrial history of the region.
