Sept-Îles lighthouse, Maritime navigation beacon in Sept-Îles archipelago, France.
The Sept-Îles lighthouse is a stone structure standing 20 meters high with a balcony and lantern room on an archipelago off the Breton coast. Its light projects across the sea to guide ships navigating these waters.
The first beacon was built in 1835, but was replaced in 1854 with a new design. This structure was destroyed during wartime and rebuilt in 1952.
The lighthouse sits within one of France's oldest private bird sanctuaries, created in 1912 to protect seabird colonies. Visitors arriving by boat can observe the birds that nest across the islands.
The site is only accessible by boat from the nearby harbor in Perros-Guirec. The building itself is closed to visitors for safety reasons, but the islands offer good viewing points.
Since 1957, the beacon has been powered by wind turbines, making it a pioneer among French maritime lights. The system shows how renewable energy was already being used for these remote structures in the 20th century.
