The ruins of Crematorium IV, which contained a gas chamber and
furnaces for burning corpses.
Several hundred thousand Jewish men, women, and children were
murdered by gas and their bodies burned here. The bodies of Jewish
and non-Jewish prisoners who died in the concentration camp were
also burned here.
The mass murder apparatus in this building functioned, with interruptions,
from March June 1943 until October 7, 1944. The building burned
down on the day of the mutiny of the Jewish prisoners in the Sonderkommando.
