Fort Rapp is part of the 14 fortifications erected in Alsace by the Prussian general Von Moltke after the fall of Strasbourg in 1870 during the Franco-Prussian War and following the siege of Strasbourg. Built between 1872 and 1874 and inaugurated on 26 September 1874, it was part of the fortifications meant to protect the city from French attacks. Since 1918 and the return of Alsace-Lorraine to France, it is named after the French general Jean Rapp. The fort is located in Reichstett, a village situated 10 minutes north of Strasbourg and belonging to the Urban Community of Strasbourg. The fort contains 200 rooms and was able to host a garrison of 800 men. It was protected by 18 cannons of 90 – 150 mm.
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.
