Flossenbürg was a Nazi concentration camp built in May 1938 by the SS Main Economic and Administrative Office. Unlike other concentration camps, it was located in a remote area, in the Fichtel Mountains of Bavaria, adjacent to the town of Flossenbürg and near the German border with Czechoslovakia. The camp's initial purpose was to exploit the forced labor of prisoners for the production of granite for Nazi architecture.
In 1943, the bulk of prisoners switched to producing Messerschmitt Bf 109 fighter planes and other armaments for Germany's war effort. Although originally intended for 'criminal' and 'asocial' prisoners, after Germany's invasion of the Soviet Union, the camp's numbers swelled with political prisoners from outside of Germany. It also developed an extensive subcamp system that eventually outgrew the main camp.
Before it was liberated by the United States Army in April 1945, 89,964 to 100,000 prisoners passed through Flossenbürg and its subcamps. Around 30,000 died from malnutrition, overwork, executions, or during the death marches. Some of those responsible for these deaths, including administrators, guards, and others, were tried and convicted in the Flossenbürg trial. The camp was repurposed for other uses before the opening of a memorial and museum in 2007.
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.
