Valeggio Castle, situated on tall spurs overlooking the River Mincio, bears the typical characteristics of a Della Scala castle, even if it was most probably built on a pre-existing structure. The Scaligeri family realised its strategic importance and erected a castle featuring the typical massive walls, square towers, battlemented keep, draw-bridge and passage guarded by a tower which is shorter than the others. The castle, built in the 13th and 14h centuries, was in full use until 1500, after which it was abandoned once it had lost its strategic importance.
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.
