Le Château-d'Oléron, Fortified coastal commune in Oléron Island, France
Le Château-d'Oléron is a fortified commune on the eastern shore of Oléron Island, surrounded by sturdy stone walls and a network of defensive structures built over centuries. The citadel defines the townscape with its characteristic fortifications and old harbor quarter.
The fortress began with an order from Cardinal Richelieu in 1630 to build initial fortifications. Under Louis XIV, Vauban later redesigned and reinforced the structures to defend the island against invasion.
Former oyster huts by the harbor now serve as artist studios where painters and sculptors create works inspired by maritime life. The spaces blend the fishing past with contemporary creativity.
The commune is accessible via the Oléron bridge from the mainland, with regular bus services to larger towns in the region. The fortified town is best explored on foot, especially during quieter hours of the day.
Inside the fortress sits an active maritime signal station that has guided ships through the Pertuis strait since the 17th century. This facility continues its original function from the time of construction.
