Château de Créminil was built in 1443 by La May family to the site of older fortification (destroyed by English Army). In 1540 Créminil was owned by Hugues de Buleux (advisor to the regent of the Netherlands and grand bailiff of Aire). After the castle was burned in 1543 it was rebuilt in the 17th century.
In 1670 it was owned by Antoine de Wignacourt and from 1687 till the Revolution by the Merchiers family. Until 1978 Créminil Castle was owned by a Mrs Lhéritier whose family had it since the Revolution.
This late medieval castle consists of an irregular polygon with twelve sides, built on a small mound surrounded by large round moat fed by water from the Laquet stream. In the 18th century 3 sides of polygon to the south were torn down and replaced by a terrace lined with stone balusters to provide a better view of the surrounding gardens. Also the facades of the buildings on the courtyard were rebuilt.
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.
