Built to Vauban's plans to protect Rochefort's naval arsenal, Fort Louvois is built on a rock that sinks at high tide, making it accessible only by boat. Designed in the shape of a horseshoe, with a central keep protected by a drawbridge and moat, it is reminiscent of the fortified castles of the Middle Ages.
A fun trail, access to wooden games and a photo studio to immortalise a moment in period costume are available to accompany the visit.
From 6 April to 2 November: accessible according to the tide calendar. Consult the timetable on fort-louvois.com
Last entry 45 minutes before closing time.
