The spot where the clothing warehouses once stood

Krema IV was located just north of the clothing warehouses, which were in a section that the prisoners called Canada. Across the road from Canada was the Central Sauna which had a shower room and disinfection chambers where the prisoners' clothing was deloused. Krema IV had a fake shower room which was actually a gas chamber.

According to Michael J. Neufeld and Michael Berenbaum, in their book entitled "The Bombing of Auschwitz: Should the Allies Have Attempted It?" the Krema IV and Krema V buildings were 220 feet long by 42 feet wide.

The Krema IV building was completely demolished, blown up with dynamite which several women prisoners stole from the factory where they were working. All the bricks were removed by Polish civilians after the war, and the ruins that visitors see today are a reconstruction, according to the Auschwitz Museum.

The prisoners who worked in the crematory buildings, removing the bodies of the victims who had been gassed, were members of a special group called the Sonderkommando. According to Dr. Miklos Nyiszli, a prisoner who did autopsies at Birkenau, each Sonderkommando group was killed after a few months and replaced by a new crew. Knowing that they were soon going to be killed, the members of the next-to-last Sonderkommando revolted and blew up the Krema IV building. A sign at Krema IV says that there were 450 prisoners who were killed by the SS during the revolt or afterwards in retaliation.

The men in the last Sonderkommando were not exterminated. Around 100 of them were marched out of the camp when it was abandoned by the Nazis on January 18, 1945. Several members of the Sonderkommando survived and three of them gave eye-witness testimony at the 1947 trial of Auschwitz Commandant Rudolf Hoess, about how the prisoners were gassed at Birkenau.
