About Ljusaklack Lighthouse

This steel lighthouse, first lit in 1932, stands 23 meters tall on a remote skerry off Furafladen, Finland. Its cylindrical tower, painted red, supports a hexagonal equipment structure and a helipad. The light emits a white flash every 30 seconds, with a geographic range of 8.9 nautical miles. The station is accessible only by boat, with the nearest port, Loviisa, 8.5 kilometers away. While the site is open to visitors, the tower itself remains closed to the public.

Why it matters: The lighthouse's sector light system is specifically designed to mark safe channels and warn of submerged dangers within the Furafladen area, while its helipad facilitates maintenance for this remote outpost.
