First record of Hatanpää dates back to year 1540 and the first manor was built in the 1690s. Hans Boije (1717-1781) improved the farming business and increased Hatanpää prosperity significantly. He also built an English garden to Hatanpää with and hired 30 gardeners to maintain it. Boije was a freemasonry and added an stone to the park with Greek engraving Egno Kyrios tous ontas antou (Lord knows his owns). The stone still exists and is known as the “grave of the freemasonry”, but no one is actually buried there.
After Boije Hatanpää manor has been owned by several families. The original main building burned in 1883 and the present one Neo-Renaissance manor was built in 1883–1885. There’s also an another Neo-Gothic manor nearby. It was built in 1898-1900 as the villa for the banker and manor owner Nils Idman. Idman was forced to sell all Hatanpää manor property to the city of Tampere in 1913. The manor was in hospital use until the new hospital was built nearby in 1930s.
Today Hatanpää manor can be booked for parties or conferences. Near the manor are beautiful rose garden and arboretum, which are very popular in the summer time.
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.
