The original lighthouse on this site, commissioned by Jean-Baptiste Colbert, was first lit in 1685.
The 1850s tower uses black and white stripes to distinguish it from the Phare des Baleines on the neighboring Île de Ré during daylight hours.
The garden surrounding the lighthouse was redesigned in 2007 to depict a nautical compass, with different plant species representing the local climate and agricultural heritage.
The lighthouse is equipped with an automated rotating beam that remains visible for approximately 52 kilometers at sea.
During the Second World War, the lighthouse was heavily fortified by German forces, who built blockhouses in the immediate vicinity.
The transition from oil-fueled lamps to electrical lighting occurred in 1930.
Phare de Chassiron is an active lighthouse situated at the northernmost tip of the Île d'Oléron, identifiable by its distinctive 1850s black and white horizontal stripes. Standing 46 meters tall, the structure was built to replace an older tower from 1836 and serves as a critical beacon for the Pertuis d'Antioche strait. Visitors can climb 224 steps to reach the lantern gallery, which offers panoramic views of the Atlantic Ocean, the Île de Ré, and the La Rochelle coastline. The base of the lighthouse features a museum dedicated to the history of the site and local maritime navigation. A large compass rose garden, designed in the shape of a navigation compass, surrounds the lighthouse and illustrates the island's botanical history. The site is part of a protected natural area known for its rugged cliffs and limestone reefs. It has been designated as a Monument Historique since 2012.

Check the horizon on clear days to spot the La Rochelle lighthouse and the iconic Fort Boyard.
Wear comfortable, flat shoes to safely manage the spiral staircase climb.
Do not attempt to walk on the slippery limestone reefs during a high tide.
Open daily throughout the main tourist season; reduced access or potential closures may occur during mid-winter months.
Maintain a quiet volume in the museum area; respect roped-off botanical garden sections.
