Auschwitz was the largest of the German Nazi concentration camps and extermination centers. Over 1.1 million men, women and children lost their lives here. It is essential to visit both parts of the camp, Auschwitz I and Auschwitz II-Birkenau, in order to acquire a proper sense of the place that has become the symbol of the Holocaust as well as Nazi crimes against Poles, Romas and other groups. Auschwitz I is where the Nazis opened the first Auschwitz camps for men and women, where they carried out the first experiments at using Zyklon B to put people to death, where they murdered the first mass transports of Jews, where they conducted the first criminal experiments on prisoners, where they carried out most of the executions by shooting, where the central jail for prisoners from all over the camp complex was located in Block No. 11, and where the camp commandant's office and most of the SS offices were located. We will spent 3:30 hours visiting, the rest of the time is travel time.
