The Cabane Vauban was built in the 17th century and is named after the famous French fortification engineer Sébastien Le Prestre de Vauban, who was responsible for the design and reinforcement of numerous coastal fortifications during the reign of Louis XIV. The hut originally served as a shelter for sentries and customs officers monitoring the coast to detect smugglers or enemy ships early. While there are several similar observation points along the Normandy coast, the Cabane Vauban near Carolles is considered the most well-known and well-preserved.
