Mers Les Bains Live Cam

Medieval Origins and Fortified Legacy

Mers-les-Bains history begins in the Middle Ages, when the fishing hamlet was part of the feudal domain of the counts of Ponthieu. Nestled on the Baie de Somme coast, this seaside resort evolved from a cluster of huts into a strategic outpost. The rugged cliffs west of Le Tréport provided natural defense, while the sandy beaches attracted merchants and pilgrims traveling between England and northern France. Throughout the 12th and 13th centuries, the town’s wooden palisades were gradually replaced by stone walls and watchtowers, vestiges of which still stand today near the Rue du Docteur Roze.
