About Trutskärsbådan Lighthouse

Trutskärsbådan is a 7-meter tall cylindrical concrete tower built in 1949. It stands on a skerry southeast of Kalix, approximately 25 kilometers from the city. The lighthouse emits two white, red, or green flashes every 3 seconds from a focal height of 8 meters. Its tower is painted red with a white lantern, and the structure includes a gallery. The operational lighthouse is part of the maritime landscape near Frevisören. Visitors can access the site, but the tower itself is not open to the public.
