Auschwitz was a collection of 40 concentration and extermination camps controlled by the Nazis during World War II and the Holocaust.
It is a difficult place to take in and process - it's not for everyone.
I personally wanted to experience this place to understand the pain that not just the Jewish people went through, but people all over Europe that were persecuted for being classed as different by the Nazis.
Some of the images are truly upsetting. The atmosphere can really be felt around the old camp. Curiously, no birds fly into the area, which some locals say is a sign of death.
I recommend a well-organised guided tour, which visitors can listen to via head sets. It is very informative...and detailed: I had to remove my head set at various times as I could not cope with listening about the terrible things which occurred here.
