About Ravmnholmen Lighthouse

Also known as: Ravmnholmen (Ravnholmen)

The Ravmnholmen lighthouse is a 6-meter tall square metal tower painted white with a red lantern roof. Situated on a skerry in a narrow passage east of Indre Vikna, its focal height reaches 8 meters. The lighthouse emits an occluded white, red, or green light every 8 seconds. This structure, which includes a lantern and gallery, has a geographic range of 9.7 nautical miles. While the site is accessible, the tower itself remains closed to the public. The nearest port, Rorvik, is 4.7 kilometers away.

Why it matters: This lighthouse is essential for safe passage through the narrow and potentially hazardous waters around the east end of Indre Vikna, guiding local fishing fleets and recreational craft. Its directional light system provides critical feedback to mariners about their position relative to the passage's dangers.
