The Archives of Prisoner Organizations (1942-1944)

A significant part of the collection is secret letters, mainly addressed to families, written by prisoners in the years 1942-1944. Apart from illegal correspondence, the collection includes official postcards, which were allowed from spring 1943. The materials in this collection were handed over by the former prisoners and their families. They document the situation in the camp at different times of its functioning as well as prisoner self-help and camp resistance movement.
