Royal Fort: Island Fortress and Historic Prison

The Royal Fort, or Fort Royal, stands as a prominent historical landmark on Île Sainte-Marguerite, the largest of the Lérins Islands near Cannes. Originally constructed in the 17th century by the Duke of Guise to protect Cannes from sea access, it has undergone several transformations throughout its history. The fort's modern appearance is largely attributed to Vauban, who redesigned it into a formidable citadel.For centuries, the fort served as a state prison, most famously holding the enigmatic Man in the Iron Mask for eleven years (1687-1698). Today, the fort is home to the Musée de la Mer (Maritime Museum), which showcases archaeological discoveries from both land and underwater excavations around the island. Visitors can explore the fort's ramparts, ancient prison cells, and museum exhibits, offering a captivating journey through its military and penal history.Île Sainte-Marguerite itself is a treasure, offering a blend of nature, culture, and relaxation. The island boasts marked trails for botanical and historical exploration, a bird sanctuary, and an underwater eco-museum with unique sculptures.
