About L'Adour Jetée Nord Lighthouse

Constructed in 1964, the L'Adour Jetée Nord stands as a 10-meter concrete block tower topped by a red horizontal band. A triangular skeletal tower was later added to this structure, extending its reach and functionality. The focal height of the light is 12 meters, and it emits a red light with one flash every 4 seconds. This light offers a geographic range of 11 nautical miles. The lighthouse is situated at the extremity of the north jetty, marking the entrance to the Rivière de l'Adour. The site is accessible to the public, though the tower itself remains closed.

Why it matters: This lighthouse is essential for guiding vessels into the Rivière de l'Adour, a river entrance known for its strong currents. Its specific red light characteristic provides a clear signal for mariners approaching from the sea.
