About Storegrunnen Lighthouse
Storegrunnen Lighthouse, located in Akershus, Norway, is situated on a shoal northwest of Drøbak in the Oslofjord. This active lighthouse features an octagonal fiberglass tower, standing 9 meters tall and rising to a focal height of 12 meters, centered on a hexagonal stone pier. Its light characteristics are an occulting white, red, or green flash every 6 seconds, visible for 11 nautical miles. The tower is painted white with two narrow black horizontal bands and a red top. Originally, an earlier structure likely incorporated a cast iron lantern, which has since been replaced. The site is open to visitors arriving by boat, but the tower itself is closed to the public.
Why it matters: This lighthouse is essential for guiding vessels through the Oslofjord, specifically warning them of the hazardous shoal it marks northwest of Drøbak. Its sector light provides precise navigation within this critical shipping lane.
