Musee de la Mer

The Musée de la Mer, housed within the Royal Fort on Sainte Marguerite Island, offers a glimpse into the island’s rich history. Originally constructed as a fortress, it later served as a state prison, most famously holding the mysterious Man in the Iron Mask. The museum displays a collection of artifacts recovered from shipwrecks, including Roman remains, alongside exhibits detailing the fort’s evolution and the stories of its prisoners. Visitors can explore the cells, including the one believed to have housed the Iron Mask, and enjoy panoramic views of Cannes and the surrounding coastline.
