The Château du Haut-Ribeaupierre is one of three castles (with the Château de Saint-Ulrich and the Château du Girsberg) which overlook the municipality of Ribeauvillé. Château du Haut-Ribeaupierre is the oldest of the Ribeaupierre's castles, its existence being known from 1084. It was constructed on an ancient Roman site. Then known as the 'Altenkastel', it was Anselme de Ribeaupierre who took possession of the castle in 1288.
Around 1368, Brunon de Ribeaupierre became owner. Dedicated to a ferocious hatred for the English, he imprisoned Sir John Harleston, who had an imperial safe conduct, in the keep from 1384 to 1387. He was only freed with the payment of a large ransom and after pressure from the Holy Roman Empire. At the end of the 13th century, the castle became a residence of the Ribeaupierres. Another noted prisoner was held in the keep in 1477. Philippe de Croy, Count of Chimay, ally of Charles the Bold, was captured by a Ribeaupierre at Nancy.
Most of the castle today is completely ruined and surrounded by dense vegetation.
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.
