Arendal Lighthouses Lighthouse

This concrete lighthouse, standing 6 meters tall with a focal height of 7 meters, was first lit in 1897. It is situated on a promontory at the easternmost point of Tverdalsøy, approximately 1.5 km east of Kilsund. The hexagonal lantern structure is painted white and topped with a red roof, mounted on two concrete piles. Its light displays occulting white, red, and green flashes on a 6-second cycle. The lighthouse grounds are open to the public, though the tower itself remains closed.

Why it matters: The lighthouse is indispensable for safe passage through the Kilsund area, marking critical turns and hazards with its directional light sectors.
