Pointe de Combrit lighthouse, Coastal lighthouse in Finistère, France

The Sainte-Marine lighthouse stands at the tip of Combrit at the mouth of the Odet, opposite Bénodet. Its square tower, 13.20 m high, is built against a two-storey keeper's house with a grey hipped roof and chimney; the tower is white with grey stone quoins and carries a red metal lantern with a red dome and gallery railing. The house has six shuttered windows and a green door, and its south wall is pierced by four windows set vertically.

Built in 1885 by Pont-l'Abbé contractor César Maubrat to strengthen the lighting of the Odet entrance, the lighthouse was occupied by German troops from July 1940 and electrified in 1943. It was damaged on 10 August 1944, its lantern destroyed; a temporary light was installed on 8 September 1945, and a new light was lit on 21 February 1952.

The lighthouse is known locally as the Feu de Combrit, and its red sector light reaches nine nautical miles while the white sector reaches twelve. Together with the Bénodet lighthouse it forms a north alignment that guides boats into the roadstead off Bénodet. Volunteers renovated the keeper's quarters between 2022 and 2023.

The peninsula is easily accessible from the road and offers a good vantage point for viewing the lighthouse and coastal landscape. It helps to watch tidal and weather conditions since the location is exposed to the marine environment.

The light works in tandem with the Bénodet lighthouse to mark a north alignment that guides ships into the roadstead off Bénodet. Its occulting light reaches twelve nautical miles in the white sector and nine in the red.
