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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
