Forcalquier Cathedral, now the Church of Notre-Dame-du-Bourguet, is a former Roman Catholic cathedral, and a national monument of France. Erected in the 12th century as a collegiate church, the cathedral of Forcalquier became a second seat of the Bishop of Sisteron in 1408, and for that reason is referred to as a co-cathedral. The diocese of Sisteron was abolished in 1801, after which the cathedral continued as a parish church.
The nave, the choir, the transept and the cloister date from the early 13th century, representing one of the first examples of Gothic style in southern France. The bell tower is from the 16th century. The church houses a panel of the Triumph of Christ by Pierre Mignard.
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.
