Cordouan Lighthouse

The Cordouan Lighthouse, awarded UNESCO World Heritage status in 2021, stands at the mouth of the Gironde Estuary in Nouvelle Aquitaine and is both the oldest functioning lighthouse in France and one of the most extraordinary maritime monuments in the world. Construction began under Henry III in the late 16th century, continued under Henry IV, and was completed in 1611 to designs by architect Louis de Foix—giving it a remarkably elaborate Renaissance architectural programme far more ornate than any utilitarian lighthouse. The structure rises 67.5 meters from a rocky plateau accessible only at low tide, and its exterior features tiered stone galleries, sculpted friezes, and a royal apartment decorated with ionic columns. Inside, visitors ascend through a royal reception room, a chapel with Gothic vaulting, and the former lighthouse keeper's quarters before reaching the lantern room and external gallery at the summit, where views extend across the open Atlantic to the west and 40 kilometres up the Gironde to the east. The lighthouse remains operational, its light visible 22 nautical miles offshore. Access is exclusively by boat from Royan or Le Verdon-sur-Mer on the Médoc shore, with departures coordinated to the tide cycle—the crossing takes approximately 30 to 45 minutes each way, and visitors typically have two to three hours on the platform and inside the lighthouse. The full excursion, including travel time, lasts a full day. Conditions on the Gironde Estuary can be choppy; the excursion runs only in fair weather and is not suitable for those prone to seasickness.
