Chassiron lighthouse, perched on a rocky cliff, is located at the north end of the Ile d’Oléron, near the town of Saint-Denis-d’Oléron.
It is the oldest working lighthouse in the department. This homing beacon, one of the first that you can see when approaching the coast, was built with stones from Crazannes (quarry located between Rochefort and Saintes). Its steps are made of Vendée granite. 46 mtall, it has 224 steps. The monument also has a full staircase where you can’t see the drop-off. It is fully automated today and monitored continually from La Rochelle. There is always someone based in Saint-Pierre d’Oléron ready to respond if there is a problem. You can visit the lighthouse year round.
