Monowitz concentration camp

Monowitz (also known as Monowitz-Buna, Buna and Auschwitz III) was a Nazi concentration camp and labor camp (Arbeitslager) run by Nazi Germany in occupied Poland from 1942 to 1945, during World War II and the Holocaust. For most of its existence, Monowitz was a subcamp of the Auschwitz concentration camp; from November 1943 it and other Nazi subcamps in the area were jointly known as "Auschwitz III-subcamps" (KL Auschwitz III-Aussenlager).
