The Auschwitz complex of camps encompassed a large industrial area rich in natural resources. There were 48 camps in all. The three main camps were Auschwitz I, Auschwitz II-Birkenau, and a work camp called Auschwitz III-Monowitz, or the Buna.
The visit starts with a 50-minute documentary movie about the liberation of the Camp. Then the museum guide will show you: the exhibition presents the documentation of life and detention of war prisoners (clothing for prisoners, bunks and other furniture in the room equipped for the prisoners, the collection of personal property taken from the deported Jews); the remaining camp buildings and its ruins, residential barracks, the ruins of the gas chambers and crematoria, several kilometers long camp fence and interior roads and unloading ramp in Birkenau.
The Birkenau camp is much less visited than Auschwitz, though it was here that the majority of captives lived and died. Covering some 170 hectares, Birkenau, at its height, comprised over three hundred buildings, of which over sixty brick and wood constructions remain; the rest were either burnt down or demolished at the end of the war, though in most instances you can still see their traces on the ground – visible along with the rest of the camp from the top ofthe tower above the entrance gate, which you can climb.
