Château de Durfort was erected on a rocky piton which overlooks the valley of the Orbieu. The present ruins are those of a strengthened habitat, including a chapel, dwellings with rectangular windows and a tower. High thick walls, cellars and wells, arched rooms of square buildings, corner turrets, watch towers and a main tower are still visible.
There is no documentary evidence for the initial construction of this fortress. The earliest written references mentioning the castle date from 1093.
After the Crusades against Cathars in the mid-13th century, the royal power confirmed its conquest of the region by building five large fortresses and a network of watch towers. The Château de Durfort was written into this defensive system, aimed at protecting the new frontiers of the Kingdom of France.
In 1659, Louis XIV signed the Treaty of the Pyrenees with the Kingdom of Spain. This treaty altered the borders, giving Roussillon to France. The frontier advanced to the crests of the Pyrenees and the various fortresses of the region lost their strategic importance. The Château de Durfort was, therefore, altered to make it more comfortable.
In the 18th century, the castle seems to have been abandoned but its isolated position served to preserve its ruins. Today, the castle is private property; it may be visited free of charge with prior authorisation from the owners. The building is not preserved or maintained; there is a risk of falling stones.
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.
