Cordouan Lighthouse

Cordouan Lighthouse rises from a rocky plateau at the mouth of the Gironde estuary, about 7 km offshore from Le Verdon-sur-Mer. It is the oldest lighthouse in France still in operation, and one of the very few in the world still staffed by keepers. In 2021 it was added to the UNESCO World Heritage List, recognized both as a masterpiece of human creative genius and as a symbol of the major stages in the history of lighthouse building.

Why is it called the "king of lighthouses"?

Construction began in the late 16th century on the orders of King Henri IV, with engineer Louis de Foix leading the design. Henri wanted more than a functional tower: the result included a vestibule, a chapel, and royal apartments — the second floor still houses a richly decorated, marble-floored chapel, making Cordouan the only lighthouse in the world with a consecrated chapel inside it. In the late 18th century, engineer Teulère added an upper section, giving the tower its current, more slender profile and bringing it to 68 meters — one of the ten tallest lighthouses on earth, decorated with pilasters, columns, modillions and gargoyles. That mix of maritime function and royal ambition earned it nicknames like "the Versailles of the sea."

What will you see inside?

The interior is striking from the first step: a spiral staircase winds past the royal apartment and the chapel on its way to the lantern room at the top. It was here, in 1823, that physicist Augustin Fresnel installed his newly invented lens, a breakthrough that would reshape lighthouse technology worldwide. When the Fresnel lens was lit for the first time on 25 July 1823, scientists travelled from across Europe to see it. The lighthouse remains staffed to this day — the last one at sea anywhere in the world to still have keepers on site.

How do you get there?

Because Cordouan sits on a rocky plateau ringed by sandbanks, the only way to reach it is by sea, on an organized boat trip departing from Royan or Le Verdon-sur-Mer. The crossing takes around 45 minutes. Landing happens at low tide, when the sand and rock flats around the tower are exposed, so visiting times shift daily according to the tide calendar — it's worth booking with some flexibility in case weather forces a change of plan.

When should you visit, and what should you bring?

The visiting season runs from April to October, depending on weather and tides. During peak season (July to mid-September), boat seats fill up fast, so booking ahead is worthwhile. Pack closed shoes that can get wet, or boots — you'll be walking across sand and rocks — plus a windbreaker, since it can turn cool out on open water even in summer.

How long does a visit take, and what does it cost?

Tickets include the round-trip boat crossing and a guided visit inside the lighthouse. Prices vary by operator and season: roughly €51 per person in low season (April–June and mid-September–November), and around €63–64 in high season (July to mid-September). Plan to arrive at the departure point at least 30 minutes before the boat leaves to collect tickets and board without rushing.

Frequently asked questions

Can I reach the lighthouse by my own boat? Licensed operator crossings are the safest option — the waters around the tower are shallow, tricky, and heavily tide-dependent, so independent approaches are not recommended.

Is the lighthouse accessible for visitors with limited mobility? Reaching the top means climbing many steps of a spiral staircase, and getting to the tower itself involves walking across sand and rock at low tide, which limits access for those with mobility difficulties.

Why is Cordouan nicknamed the "king of lighthouses"? Because of the monumental architecture commissioned by Henri IV — including a chapel, royal apartments, and elaborate sculpted decoration — features far beyond what a purely functional structure would need.

Is Cordouan still an active navigational aid? Yes. It continues to function as a working lighthouse and remains the only one in the world with a permanent on-site keeper.
