The Basilica church of St. Ursula was is built upon the ancient ruins of a Roman cemetery. The church has an impressive reliquary created from the bones of the former occupants of the cemetery. It is one of the twelve Romanesque churches of Cologne and was designated a Minor Basilica in 1920. While the nave and crossing tower are Romanesque, the choir has been rebuilt in the Gothic style.
The Golden Chamber, or Goldene Kammer, of the church contains the alleged remains of St. Ursula and her 11,000 virgins who are said to have been killed by the Huns, possibly around the time of the Battle of the Catalaunian Plains. The original legend said only 11 virgins accompanied St. Ursula but the number grew over time, eventually to 11,000. The walls of the Golden Chamber are covered in bones arranged in designs and/or letters along with relic skulls. The exact number of people whose remains are in the Golden Chamber remains ambiguous but the number of skulls in the reliquary is greater than 11 and less than 11,000. These remains were found in 1106 in a mass grave and were assumed to be those of the legend of St. Ursula and the 11,000 virgins. Therefore, the church constructed the Golden Chamber to house the bones. The bones themselves are neatly arranged in 'zigzags and swirls and even in the shapes of Latin words.'
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.
