Musee de la Mer, Ile Sainte-Marguerite

A museum of underwater archeology & land

featured in Sights & sites

Situated within the Royal Fort on Ile Sainte-Marguerite in the Bay of Cannes, this museum is a place not only of learning but also of rich history.

This historical monument overlooks the sea and is home not only to the Musee de la Mer, but you can also visit the old state prison cell and the famous iron mask, where the mysterious prisoner was imprisoned for eleven years. In addition to this, you can see the Huguenot Memorial and murals by Jean Le Gac on the theme of the imprisoned artist.

On the first floor, you will find archaeological materials that were discovered in the sea and originate from Roman and Saracen wrecks. Tradelière Batéguier (ceramics, cargo of amphorae, glasses...) and fragments of Roman wall paintings from land excavation of Île Sainte-Marguerite are also on display. A space for temporary exhibitions opens on a wide overlooking the sea facing terrace Cannes coastline, the Southern Alps in Cap d'Antibes and the Esterel.

Watch out for

Dogs are allowed inside the museum but a word of warning... you must carry them at all times! So probably not good for any large breeds!

It also closes for lunch.

Visitor comments

  • "Musée de la Mer has a nice collection of ancient jars found off the coast of Sainte Marguerite Island. There is the prison cell of the famous Man in the Iron Mask.
