Presentation

Christophe Joguet, salt worker at the "Tenue de Mareil" saltworks in the Lyarne marshes at Moutiers-en-Retz, shares his passion for white gold with you through quality products and guided tours.

Located between sea and countryside, in the Lyarne marsh, this salt marsh was rehabilitated by enthusiasts in the 2000s. Since then, the salt works have been revived by the Patrimoine 2MB association.

Christophe Joguet, salt worker at the Tenue de Mareil saltworks, arrived at the end of 2023. He succeeds salt worker Mélanie Daspremont, who now operates the Ileau saltworks in Villeneuve-en-Retz.
