France's oldest working lighthouse, built from 1584-1611, features royal apartments, a chapel, and extraordinary Renaissance architecture at the mouth of the Gironde
The Cordouan Lighthouse stands on a rocky reef at the mouth of the Gironde Estuary, approximately 7 kilometres offshore from both Royan and Le Verdon-sur-Mer in Nouvelle-Aquitaine. Construction began in 1584 under Henri III on the commission of Louis de Foix, a French engineer who had previously worked in Spain, and the tower was completed in 1611. The lighthouse rises 67.5 metres above the reef and comprises four superimposed sections of highly ornate masonry: a Renaissance-styled lower section with a grand entrance vestibule and apartments for the keeper; a royal apartment (the Salle du Roi) on the first floor featuring carved stone chimney pieces and tapestry hooks, intended for royal visits; a richly decorated Gothic chapel dedicated to Notre-Dame de Cordouan on the second floor, with stained glass and carved stone altars; and the lantern gallery at the summit, which has been continually updated since the 17th century and remains an operational navigational light today. The lighthouse was classified as a historic monument in 1862, among the first in France to receive this status. UNESCO inscribed Cordouan as a World Heritage Site in July 2021, recognising its exceptional universal value as a masterwork of Renaissance marine engineering and as the only lighthouse in the world to combine monumental architecture with a working navigational function over more than four centuries. Access is by boat from Royan or Le Verdon-sur-Mer; the crossing takes approximately 45 minutes and landing on the reef is tide-dependent. Visitors ascend the 301 steps to the lantern gallery. The combined boat-and-entry ticket costs between €28 and €35 depending on the operator and season.
Why it matters

Its ornate Renaissance and Baroque interior — including a royal apartment and a chapel — is unique among lighthouse architecture worldwide.

- Tide-dependent boat crossing from Royan or Le Verdon-sur-Mer — an integral part of the lighthouse experience
Tips for visiting
- Boat trips depart from both Royan and Le Verdon-sur-Mer; landing on the reef is only possible for approximately 3–4 hours around low tide — book in advance and check the operator's weather and tide policy
- The combined boat-and-entry ticket (€28–€35) should be booked directly through authorised operators based in Royan or Le Verdon-sur-Mer; the tourist offices in both towns can assist
- Wear rubber-soled footwear — the reef and lower steps are wet and slippery
- Allow 3–4 hours including the boat crossing each way and time inside the lighthouse
- The chapel and royal apartment are on lower floors; even visitors who cannot manage all 301 steps can access the most historically significant interior spaces
When to visit
May to September offers the most reliable weather and the greatest frequency of boat departures. June and early September are ideal: days are long, sea conditions are generally calm, and the estuary light in the late afternoon is exceptional for photography.
Accessibility
The Cordouan Lighthouse is not accessible to wheelchair users or visitors with significant mobility impairments. The boat landing on the reef is uneven, and the interior consists of 301 stone steps with no lift. The lower floors, including the chapel and royal apartment, are accessible to those who can manage moderate stair climbing.
