(German: Bauabschnitt IId – construction segment 2, sector d)

One of the nine camps built by the Germans in Birkenau, and one of the three men's camps that existed from 1943. It opened in July when prisoners were transferred there from camp BI b. Apart from BII d, men were also held in the quarantine (BII a) and the hospital (BII f) sectors. Prisoners occupied 25 of the 40 wooden barracks there. On average there were 8–12 thousand men in the camp, which works out to 500 per barrack. Two of them, additionally fenced‑in and isolated, were occupied by the prisoners in the penal company and the Sonderkommando.
