The Abashiri Prison Museum is an outdoor museum of history. Today the buildings are preserved and open to the public. Older parts of the prison were relocated to the base of Mount Tento in 1983, where they operate as the country's only prison museum.
In April 1890, the Meiji government sent over a thousand political prisoners to the isolated Abashiri village and forced them to build roads linking it to the more populous south. Abashiri Prison later became known for being a self-sufficient farming prison, and was cited as a model for others throughout Japan.
Most of the prison burned down in a 1909 fire, but it was reconstructed in 1912. It took on its current name in 1922. In 1984, the prison moved to a modern reinforced concrete complex.
Due to the 1965 film Abashiri Prison and its sequels, the prison became a popular tourist attraction. The prison is also known for its wooden nipopo (ニポポ) dolls carved by its inmates.
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.
