Bengtskär lighthouse, Archipelago National Park

Bengtskär Lighthouse is located in the Archipelago Sea about 25 kilometers south west of Hanko, Finland. The lighthouse was built in 1906 on the Bengtskär skerry where it rises 52 meters above sea level and is the highest one in the Nordic countries. The lighthouse had been planned for some time, but after the steamer s/s Helsingfors ran aground in 1905 in the vicinity en route from Lübeck to Helsinki resulting in several crew members trapped and drowned on board, the project gained urgency and was completed during the following year. Soviet troops stationed in Hanko during the Continuation War, disturbed by a Finnish observation post in the light house tried to blow up and destroy the lighthouse during the Battle of Bengtskär in 1941.
