A remarkable site, the Guérande salt marshes represent both a natural and a historical heritage. Even today, over 200 paludiers, or salt harvesters, gather the salt using millenary methods and know-how. Current techniques date from the ninth century.
Humans have developed the landscape and the salt marshes cover vast stretches, featuring beautiful arabesques drawn by the basins where salt remains after evaporation. Grey salt and Fleur de Sel from Guérande are known and prized around the world.
