Gross-Rosen concentration camp was a German network of Nazi concentration camps built and operated during World War II. The main camp was located in the village of Gross-Rosen not far from the border with occupied Poland, in the modern-day Rogoźnica, Poland.
At its peak activity in 1944, the Gross-Rosen complex had up to 100 subcamps located in eastern Germany, Czechoslovakia, and on the territory of occupied Poland. The population of all Gross-Rosen camps at that time accounted for 11% of the total number of inmates incarcerated in the Nazi concentration camp system.
KZ Gross-Rosen was set up in the summer of 1940 as a satellite camp of the Sachsenhausen concentration camp from Oranienburg. Initially, the slave labour was carried out in a huge stone quarry. In October 1941 the SS transferred about 3,000 Soviet POWs to Gross-Rosen for execution by shooting. Gross-Rosen was known for its brutal treatment of the so-called Nacht und Nebel prisoners vanishing without a trace from targeted communities. Most died in the granite quarry. In 1942, for political prisoners, the average survival time-span was less than two months.
At its peak activity in 1944, the Gross-Rosen complex had up to 100 subcamps, located in eastern Germany, Czechoslovakia, and occupied Poland. In its final stage, the population of the Gross-Rosen camps accounted for 11% of the total inmates in Nazi concentration camps at that time. A total of 125,000 inmates of various nationalities passed through the complex during its existence, of whom an estimated 40,000 died on site, on death marches and in evacuation transports. The camp was liberated on February 1945 by the Red Army.
References:The Citadelle of Quebec is an active military installation and official residence of both the Canadian monarch and the Governor General of Canada. It is located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City. The citadel is the oldest military building in Canada, and forms part of the fortifications of Quebec City, which is one of only two cities in North America still surrounded by fortifications, the other being Campeche, Mexico.
The first fortifications in Quebec were built by the Governor General of New France Louis de Buade, and completed just in time for the Battle of Quebec in 1690.
After the British conquest in the second half of the 18th century, the problem of Quebec City's defences grew more acute.
