The Chassiron lighthouse stands at the northern tip of the île d'Oléron. It was built starting in 1834, replacing a tower built on the site in 1685. It stands 50 meters (164 ft.) tall. That's 224 steps from the ground up to the top. Walt and I walked up there to take in the views. Cheryl kept her feet on the ground and walked around the tip of the island, accompanied by Callie on a leash.
For comparison, the towers of Notre-Dame cathedral top out at 69 meters... Still, the Chassiron light is visible from a distance of 28 nautical miles. Only one other lighthouse in France — le phare de Cordouan, 35 miles south — has been in operation longer than Chassiron.
