Sint-Petrus-en-Pauluskerk (Church of Saint Peter and Saint Paul) is built on the ashes of a previous church that occupied the site. King Leopold II enthusiastically supported a plan to build a new and more magnificent church. Construction started in 1899 and was completed and consecrated by Bishop Waffelaert on August 31, 1908. Its stained glass windows were destroyed during the two World Wars and were replaced by windows by Michiel Martens. The church is 70 meters long and 30 meters wide. Its spires are 72 meters high.
The church was built in the Neo-Gothic style according to plans by architect Louis Delacenserie, who based his design on the Gothic Cologne Cathedral and the Neo-Gothic Votivkirche in Vienna.
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.
