English: Memorial for the Chełmno extermination camp, in Rzuchów forest (midway on the road from Chełmno to Koło, this glade is about 200 metres away form the road), where the dead bodies were discharged from the gas vans, in order to be placed in mass graves ; thereafter, the corpses had been incinerated in a neighbouring glade a few hundred metres further. Globally, about 150,000 people, Jews above all, had been exterminated in Chełmno, mainly during year 1942 : that extermination camp, the first one of this kind, began to operate in December 1941, a few weeks before the official start of the "Final Solution to the Jewish Question" (Wannsee Conference, 20 January 1942, under the direction of SS general of the Police Reinhard Heydrich, missionned by Reichsmarschall Hermann Göring).
