This electrified fence, and its guard towers, is at the extreme outer edge of Auschwitz-Birkenau. Out of the picture to its left are the barracks of “A” lager. This was the quarantine section of the men’s camp where new arrivals selected for slave labor were warehoused. Interiors of these barracks can also be viewed in this exhibition. This gives a sense of the enormous size of Birkenau. From the far end of this photo to the opposite end of the camp behind us, it is almost exactly one kilometer.
