From April to October, the Fort opens its doors to visitors, offering a unique immersion in French military history. Crossing the drawbridge, you enter a fascinating world where every stone tells a story. The courtyards of honour, the artillery platforms, the gun cellars, the gunpowder shops and the casemates plunge you into the daily lives of the soldiers who watched over these ramparts.
Exploring the cave-shelter and the double caponier is a must. The cave-shelter, dug in response to advances in artillery, offers a glimpse of the military adaptations of the 19th century. As for the double caponier, the fort’s last line of defence, it illustrates the ingenuity of the strategists of the time in protecting the fort against enemy assaults. These two elements demonstrate the military expertise and ingenuity deployed to protect this strategic fortress.
