Tucked away in the Fort Royal on Île Sainte-Marguerite in the Bay of Cannes, the Musée du Masque de Fer et du Fort Royal (formerly the Musée de la Mer) is an archaeology museum exploring land and sea.
Offshore from Cannes, on the largest of the Lérins Islands, Ile Sainte-Marguerite, the musée de la Mer occupies the oldest part of the Vauban style Fort Royal.
