About Rosmunnholmen Lighthouse

A 6-meter tall fiberglass tower marks the Rosmunnholmen lighthouse, which stands 24 meters above sea level. The structure is painted white with two black horizontal bands, and its lantern roof is red. It emits an occulting white, red, and green light, with a 2-second cycle. This light replaced a previous, older structure. The lighthouse is situated on a small island in the Mokstrafjord, north of Selbjørn, near Austevoll. Access to the site is possible by boat, though the tower itself is closed to visitors.

Why it matters: The lighthouse's directional light sectors are essential for guiding vessels through the Mokstrafjord and delineating safe channels north of Selbjørn.
