Bengtskär lighthouse is located in the Archipelago Sea 28 kilometers south west of Hanko, Finland.[1] The lighthouse was built in 1906 on the Bengtskär skerry where it rises 52 meters on sea level and is the highest one in the Nordic countries. Soviet landing troops tried to explode the lighthouse during the Battle of Bengtskär during the Continuation War in 1941. The lighthouse is nowadays a popular tourist destination[2] and is visited roughly 13 000 to 15 000 tourists every year.[3]
