Cremolino was the main feud of the Monferrato branch of the Malaspina marquises, lords of the Lunigiana. The castle was built in the late 13th century, around a tower that dates from the year 1000, by Tommaso Malaspina, who inherited the estate from his mother Agnese, the last heir of the Aleramici Del Bosco marquises.
When the Malaspina line of Cremolino died out at the end of the 15th century, the castle was enfeoffed by the Marquis of Monferrato to the Sauli and Centurione families from Genoa, and from the mid-16th century to the Dorias. At the end of the 18th century it passed by marriage from them to the Serra marquises of Genoa.
Thanks partly to its triple band of walls, the castle was never conquered and as a result its medieval character, with the drawbridge, 14th-century tower and mighty 15th-century keep, has been preserved intact. The bastions of this medieval fortress look out over one of the most beautiful views of the Alto Monferrato and the Alps. The owners live permanently in the castle, which is surrounded by a 19th-century park of tall trees, boxwood topiary, roses, hydrangeas and fish ponds full of water-lilies.
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.
