Ruins of Krema II

Ruins of Krema II gas chamber, looking north towards International Monument

Krema II was a one-story brick building with an attic and two underground rooms, located on the south side of the main camp road in the Auschwitz II camp, aka Birkenau. Krema III, located on the north side of the main camp road, was a mirror image of Krema II. The gas chambers in both Krema II and Krema III were in underground rooms situated in a north-south direction. The ground-floor brick buildings which housed the ovens in both Krema II and Krema III were situated in an east-west direction, forming a T-shape.

In the photo above, the roof of the underground gas chamber in Krema II can be seen in the foreground. The roof of the undressing room, which is at right angles to the gas chamber, can be seen on the left. The International Monument, built in 1965, is in the background. When the Birkenau camp was in operation, the main camp road ran from east to west over the ground where the monument now stands, and intersected another road which went north to Krema IV and Krema V which had gas chambers, disguised as shower rooms, on the ground floor.

Krema II was the site of the largest mass murder in the history of mankind. It was here that over 500,000 Jews were gassed to death with Zyklon-B, an insecticide that was also used to disinfect clothing in the camp. Robert Jan Van Pelt, a noted Holocaust historian, called Krema II the "Holy of Holies." It is a place that demands great reverence and respect for the thousands of innocent victims who perished here.

The photo above was taken with the camera facing north. In the center of the photo is what appears to be a hole in the concrete roof, made when the building was blown up with dynamite on January 20, 1945.

The 210-square-meters underground gas chamber room survived the blast and it is still partially intact. It is possible to climb down into the southernmost quarter of the Krema II gas chamber through a hole in the roof; a few people have descended into the gas chamber without permission, including two revisionists who have written unofficial and controversial reports about the condition of the only remaining gas chamber at Birkenau.

Model of Krema II gas chamber and crematorium

The photo above shows a model of the Krema II gas chamber in the US Holocaust Memorial Museum. On the left is the underground room where the victims were forced to undress. The gas chamber is shown on the right side of the photo. A small elevator was used to lift the bodies up to the ovens, which were on the ground floor of the building. The prisoners who worked in the crematorium lived in the attic space above the crematorium.

After descending into the undressing room, the prisoners were instructed to take off all their clothes; they were told that they were going to take a shower. Then the naked victims, men, women and children all together, walked to the end of the undressing room where there was a door into a small vestibule, called the Vorraum. A door on the south wall of the Vorraum led into the gas chamber, which was at right angles to the undressing room. The gas chamber was disguised as a shower room with fake shower heads, which are now gone. The victims soon learned, to their horror, that they had been duped. The shower room was actually a gas chamber where Zyklon-B gas pellets were used to murder the victims.

There was an exterior entrance with a staircase on the north side of the building which led to the Vorraum of Krema II so that the SS men could enter Leichenkeller 1, the gas chamber, without going through Leichenkeller 2, which was the undressing room. In case of emergency, the gas chamber could be used as a bomb shelter for the SS men working in the area, since it had a gas-tight air raid shelter door.

The Krema II and Krema III buildings were originally planned to be built in the Auschwitz I main camp. The original blueprints showed a corpse slide which was located at the intersection of Leichenkeller I and Leichenkeller 2 so that dead bodies could be rolled into the two corpse cellers. When Krema II and Krema III were built at Birkenau instead, the corpse slide was replaced by stairs on the side of the building which faced the main camp road, which was the north side for Krema II and the south side for Krema III. These stairs, facing the main camp road, were for the use of the SS men; the gas chamber victims used the stairs which went down into Leichenkeller 2; these stairs faced the north-south road which intersected the main camp road. This intersection no longer exists because the International Monument was built on top of the main camp road at the west end of the camp.

For maximum effectiveness, the manufacturer's recommendation was that the Zyklon-B pellets, which were used for gassing the prisoners, should be heated to 78.3 degrees and that the poison gas should be circulated throughout the room by the use of a blower, but Krema II had no device for heating the pellets, nor for circulating the gas.

According to the testimony of survivors, Krema II did have a ventilation system with vents on the roof to air out the room after the gassing, since there was only one door into the gas chamber and the room could not be properly ventilated just by opening the door. The ventilation for both the undressing room and the gas chamber at both Krema II and Krema III was included on the blueprints and the ventilation system was mentioned in other documents pertaining to these buildings.

According to a book entitled, "The Bombing of Auschwitz: Should the Allies Have Attempted It?" by Michael J. Neufeld and Michael Berenbaum, the gas chambers in Krema II and Krema III were 99 feet long by 23 feet wide. The undressing rooms in both buildings were 162 feet long by 26 feet wide. The long part of these T-shaped buildings, which was above ground, was 99 feet long by 37 feet wide, and the overall size of the long part of the buildings was 352 feet by 41 feet.

The Krema II gas chamber and the undressing room were both about five feet underground, but not directly underneath the brick one-story building which housed the cremation ovens. Before Krema II and Krema III were blown up, the roof of the gas chamber and the roof of the undressing room were covered by three feet of dirt with a grass lawn on top. There were four holes in the roof of the gas chamber in both Krema II and Krema III; the roofs were made of reinforced concrete, six inches thick. Through these four holes on the roof, an SS man, wearing a gas mask, lowered an open can of Zyklon-B gas pellets down into four wire-mesh columns inside the gas chamber. When the gassing was finished, the pellets were retrieved and sent back to the Degesch company so that they could be reused. Michael Kula, a survivor, testified as an eye-witness to the use of wire-mesh columns for the Zyklon-B pellets, but these columns are no longer in existence.

Steps down into the undressing room in the center background

The photo above shows the steps that led down into the undressing room, which was called Leichenkeller 2 (Corpse Cellar #2) on the blueprint of the building. The gas chamber was called Leichenkeller I (Corpse Cellar #1) on the blueprint. In the background is the grove of trees that marks the western boundary of the Birkenau camp, with a guard tower in the right hand corner of the photo. To access the undressing room at Krema II, the prisoners walked down the main camp road and then turned south on a road that intersected the main camp road.

On the far right in the photo above, you can see the steps of the International Monument which are only three or four feet from the entrance to the undressing room where 500,000 Jews descended to their death. In the foreground of the photo above is the remains of the ground-floor furnace room.

The photo below shows another view of the steps down into the undressing room, which was a bit larger than the gas chamber. An orchestra, composed of prisoners, played light classical music as the victims descended down the steps. Note that the undressing room does not appear deep enough to be an underground room. The concrete roof of this room was 3 feet above ground and covered with dirt.

Steps down into the undressing room for Krema II gas chamber

The gassing of the Jews at Birkenau stopped on the first of November 1944, on the orders of Reichsführer-SS Heinrich Himmler, the head of all the concentration camps. The roof of the Krema II brick building was taken off and the cremation ovens were lifted out with cranes. The fake shower fixtures on the ceiling of the gas chamber were removed and all traces of them are now gone. Then the wire-mesh columns inside Krema II, into which the poison gas pellets had been poured, were removed and the holes in the roof were closed up and cemented over so skillfully that no trace of them can be seen today.
