About Tjeldholmgrunnen Lighthouse
This lighthouse stands 15 meters tall on a post, topped with a lantern and gallery. Its structure is painted white and features a single narrow red horizontal band, with a red lantern roof. The operational light emits a red isophase flash every 4 seconds, visible for nearly 12 nautical miles. It is located off the northeastern coast of Tjeldholmen, an island west of the Løperen and north of Asmaløy, near Hvaler. The site is open for public access by boat, though the tower itself remains closed.
Why it matters: The lighthouse warns vessels of the Tjeldholmgrunnen shallow area, ensuring safe passage through the coastal channels between Tjeldholmen and Asmaløy.
