Auschwitz I

Two weeks ago I visited Auschwitz concentration camp. It was a dreadful and powerful experience. Makes you think about the human condition.
Auschwitz was a network of concentration and extermination camps built and operated in Polish areas annexed by Nazi Germany during the Second World War. It was the largest of the Nazi concentration camps, consisting of Auschwitz I (the Stammlager or the base camp); Auschwitz II - Birkenau (the Vernichtungslager or extermination camp); Auschwitz III - Monowitz (a labour camp); and 45 satellite camps.
In this photo you can see Auschwitz I which served as the administrative centre for the whole complex.
