It is far from imagining that here, in the 18th century and until the first half of the 20th century, human activity, linked to peat extraction, was in full swing. And yet these bodies of water bear witness to this exploitation in the past. The arrival of coal put an end to this activity and nature has now reclaimed its rights. Without human intervention, these plains would naturally fill up and make way for a reed bed and then for a peat basin.

Les Escargots du Marais is a local production in Clairmarais that focuses on the breeding and processing of snails. The initiative is new in the region and offers a wide range of products, such as snails as an aperitif, ready-made meals, and preserves. The production company is 100% local, from breeding to processing, and is easy to find thanks to the signs that lead along the route to the Grange Nature.
