The Sainte-Marine lighthouse stands on the tip of Combrit next to the fort. It is located at the mouth of the River Odet, just opposite the port of Bénodet. The lighthouse was built in 1885: a fixed white light on a square tower at the gable end of the main building, 13.20 m high, by a contractor from Pont-l'Abbé, César Maubrat. The lighthouse was electrified in 1943, then damaged by German troops on 10 August 1944.
Together with the light from the Bénodet lighthouse, it forms a line of sight to the north, allowing you to reach the harbour in front of Bénodet.
