Haltdalen Stave Church was originally located in Haltdalen, but today it is on display at the Sverresborg museum in Trondheim. The church was probably built in the 1170s. The church on display is a rebuilt version of two churches from Ålen and Haltdalen. The western wall and the portal is from the old Ålen church. This is a single-nave stave church of the east Scandinavian-style, and it is the only one that is preserved.
References: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.
