This 17th-century maritime fortification was built on a rock submerged at high tide, between the Ile d'Oléron and the Bassin de Marennes. Its construction, ordered by Louvois, Louis XIV's Minister of War, took place between 1691 and 1694, based on plans by Vauban.
The aim was to cross cannon fire with the Citadelle d'Oléron to defend the Rochefort naval arsenal. 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.
It was listed as a historic monument in 1929.
Today, Fort Louvois opens its doors to you for an unusual and surprising visit!
