Pavone Castle was originally built between the 9th and the 11th century. At the beginning of the 13th century, the castle went to the Romano family and, several years later, Oberto, the new bishop of Ivrea, got it back. In the 14th century, its first and major reconstruction took place. In the 15th century, the castle was abandoned, but, at the end of the century, Bishop Bonifacio Ferrero gave the go-ahead for new reconstruction: building a staircase, enlarging the residential area, and recuperating the external tower.
Wars between Francesco I and Carlo V caused new damage and destruction to the castle, which, following the Napoleonic invasions, was almost completely destroyed.
In 1888, the castle started undergoing renovation works under the direction of architect Alfredo d'Andrade, which were later completed, after his death, by his son Ruy d'Andrade. Several years ago, the castle was turned into a hotel-restaurant and Convention Center.
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.
