Mobilia museum specializes in cars and road traffic. The exhibitions illustrate the history of the field in Finland, where long distances have always given both roads and vehicles particular importance. The exhibitions change annually, focusing on different sub-themes of automobile traffic. The exhibitions are planned with foresight; the exact subjects are known years ahead. A wide collection of photos and other objects is also on display in Mobilia.
At the moment the permanent exhibition includes 26 classic cars. There is also the Rally Hall of Fame, an exhibition that depicts international rally stars and rally cars.
Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
