Le Château-d'Oléron

The citadel stands on the eastern coast of Oléron Island, surrounded by sturdy stone walls and featuring a network of defensive structures from different periods.

Cardinal Richelieu ordered the construction of the initial fortifications in 1630, which later expanded under Louis XIV with Vauban's architectural modifications to protect against foreign invasions.

The former oyster huts along the port have transformed into workshops where local artists create and display paintings, sculptures, and maritime-themed crafts.

Visitors can reach the commune via the Oléron bridge from mainland France, with regular bus services connecting to major towns in Charente-Maritime department.

The citadel contains a functioning maritime signal station that guides vessels through the Pertuis straits, maintaining its original purpose from the 17th century.
