Saint-Jacques-en-Sarzeau Lighthouse

This white and red cylindrical masonry tower, measuring 5 meters in height, has its light source at a focal elevation of 7 meters. Situated at the extremity of the mole in Saint-Jacques-en-Sarzeau, south of the Presqu'île de Rhuys, the building includes a gallery but lacks a lantern. Its light covers a distance of 9.3 nautical miles. The illumination displays two red occulting flashes across a 6-second interval. Access to the location is permitted, while entry into the tower is prohibited.

Why it matters: This navigation aid assists local vessels and fishing craft approaching or departing the small harbor of St. Jacques-en-Sarzeau, indicating the mole's termination. Its red occulting signal helps avoid contact with the harbor works, promoting secure passage in this active local channel.
