The story goes... Unlike Kremas 2 & 3 which were designed as morgues, but simply modified to fit a purpose. Auschwitz-Birkenau's Kremas 4 & 5 were specifically designed and built to kill Jews with poison gas.
Krema 5 was the last gas chamber/crematorium to be destroyed by either camp prisoners or the Germans.
