Welcome to Île Ste-Marguerite
An easy half-hour loop around the island's western tip passes a WWII German bunker, an elevated viewing platform and a wetland teeming with birdlife.
The island served as a strategic defence post for centuries. Fort Royal, built in the 17th century by Richelieu and later fortified by Vauban, today houses a museum with exhibits on the island’s Greco-Roman history, artefacts from numerous shipwrecks, and a small aquarium focusing on Mediterranean fauna and flora. Museum admission also includes the former state prison, where the famous Man in the Iron Mask was held.
Even without a museum ticket, you can wander the fort's ramparts, which boast grand views of the coast.
