A prisoner block in Auschwitz I where, from April 1943, the gynecologist Carl Clauberg’s experimental station was located. From 150 to 400 Jewish women were quartered there, and he conducted sterilization experiments on them. They were officially listed in the camp records as “female prisoners for experimentation.” Some of them died during the experiments, and many were specially put to death for autopsy purposes. The windows of the building, looking out on the courtyard where the Death Wall was located, were permanently shuttered so that the women could not observe the executions taking place there. In May 1944, the experimental station was moved to the so‑called camp extension.
