Fodor's Expert Review Musée de la Mer

This complex is famous for reputedly being the prison of the Man in the Iron Mask. Inside, you can see his cell and hear his story. The truth of his captivity is not certain; however, it is true that many Huguenots were confined here during Louis XIV's religious scourges. You'll also find a Roman boat dating from the 1st century BC and a collection of amphorae and pottery recovered from ancient shipwrecks.
