Eden 62 and the Land of Art and History offer you to discover this land, space of biodiversity and history. Once a marsh, the site was backfilled by various deposits throughout the mining era. At that time it was mainly black shale, ash, red shale but also a whole heap of fuels which still today cause the combustion of certain parts of the soil, forming fumerolles in places. The seedings related to the requalification of the soil as well as the natural plant colonization offer today a landscape and atmospheres very contrasted to discover. 2h30 RDV: parking of the site, rue de la liberté, in Fouquières-les-Lens
