Chełmno extermination camp

Chełmno, or Kulmhof, was the first of Nazi Germany's extermination camps and was situated 50 km (31 mi) north of Łódź, near the village of Chełmno nad Nerem.

However, the West German prosecution, citing Nazi figures during the Chełmno trials of 1962–65, laid charges for at least 180,000 victims. The Polish official estimates, in the early postwar period, have suggested much higher numbers, up to a total of 340,000 men, women, and children. The Kulmhof Museum of Martyrdom gives the figure of around 200,000, the vast majority of whom were Jews of west-central Poland, along with Romani people from the region, as well as foreign Jews from Hungary, Bohemia and Moravia, Germany, Luxembourg, and A
