About Otterhällen Lighthouse
Otterhällen, built in 1963, is a white cylindrical tower standing 6 meters tall on a small islet at the north entrance to Söderhamn. It features a green lantern room with a yellow horizontal band. The lighthouse emits two white, red, or green flashes every six seconds, providing a geographic range of 10.4 nautical miles. The site is accessible to the public, though the tower itself remains closed. Its nearest port is Sandarne, 2.3 kilometers away. This operational lighthouse serves as a marker for vessels entering the Söderhamn municipality.
Why it matters: The lighthouse's distinctive color-changing light serves to precisely delineate safe channels and warn of shoals at the harbor entrance, aiding navigation into Söderhamn.
