Observatoire Sainte-Cécile

Built in 1863 by Paul Régnault, chief engineer of the Winter Town and nephew of the Pereire brothers, this metal tower is capped by a circular observatory offering a breathtaking view of the town of Arcachon and all of the Basin.
Inside, take a narrow spiral staircase to reach the top of this belvedere, which rises to 75m high.
