From the original Château de Loubens castle remains today the main 15th and 16th century building and three towers which still bear their original Renaissance design. The north facade, facing the park, is framed by two defensive round towers. The high west walls plunge into a pond, remains of the original moat. On the south side, the castle sunny terrace overlooks the surrounding countryside. An hexagonal tower embeded into the Renaissance main building brings rhythm to the facade.
The 10 acres around the castle have been redesigned using to the best the remains of its previous successive settings. The most ancient elements date from the Renaissance period. Among them, some remarkable box trees and 500 years old green oaks. A little parterre in classical French style on the north side leads to 4 squares of wild prairies framing a large alley planted with limetrees in 1825. Inside the grove, a stream, a bassin and a fountain bring animation and coolness into the woods.
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.
