About Hälsö Nedre Lighthouse

The Hälsö Nedre lighthouse, built of concrete in 1884, is a cylindrical tower 7 meters high. It is situated on a point of land at the eastern end of the island of Hälsö, within the municipality of Öckerö. The white tower features a lantern with a green roof. Its light exhibits an occulting white, red, and green characteristic with a 4-second cycle. The geographic range of the light is 9.3 nautical miles. The site is open to the public, but the tower itself is closed.

Why it matters: This lighthouse serves as a range light, guiding vessels into the harbor of Hälsö by indicating the correct bearing through the approach channels. Its directional light, which changes color, offers precise navigation to prevent groundings and collisions in the local waters.
