Fort Louvois is a 17th century coastal fort built on a submerged rock between Oléron Island and the Marennes Basin.It was built from 1691 to 1694 according to the plans drawn up by Vauban. It was design to protect the southern approach to the Charente estuary by catching enemy ships in a crossfire with the citadel at Oléron. This prevented an enemy from sailing up the river to attack the naval dockyards at Rochefort. Today, Fort Louvois is open to the public offering a unique and fascinating visit!
