Fort Louvois
A horseshoe-shaped small fort in Marennes Bay, reachable on foot along a stone causeway at low tide and by small boat at high tide.
Fort Louvois was built at the end of the 17th century and, together with the castle on the opposite Île d'Oléron, guarded the Maumusson Strait. Inside is a small exhibition on oyster farming and coastal defence, and from the terrace you can see the Oléron bridge and the oyster beds of the bay. At low tide you can walk to it along a stone path, while at high tide small boats ferry visitors across. Opening seasons and hours depend on the tides.
