About Loire Estuary South Side Lighthouses Lighthouse
A cylindrical concrete tower, 6 meters tall, stands on the south jetty at St.-Michel-Chef-Chef, marking the southern entrance to the Loire Estuary. Established in 1965, the structure features a castellated top. Its light emits an occulting white or green signal every 4 seconds, visible for 9.3 nautical miles. The tower's focal plane sits 7 meters above sea level. The site is open to the public, but the tower is closed.
Why it matters: This light is essential for safe navigation into Port de Comberge, a local harbor situated within the busy Loire Estuary. Its unique directional white or green light precisely guides vessels along the south breakwater, preventing potential groundings and ensuring clear passage for maritime traffic.
