In 1846 the merchant Anders Öhrström built a lavish residence for himself and his family – The Öhrström estate (Öhrströms gård) on Nygatan has been meticulously renovated and its period rooms and features are a true asset to Arboga. The estate is now home to Arboga Museum.
The museum also houses a large photographic archive and library in addition to modern facilities for exhibitions and other events. An additional feature of the museum is the collections of silver, tin and alder root on display, all made by famous Arboga craftsmen.
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.
