Students who visited Auschwitz this week said they could not put into words the shock they felt after learning about the events which happened at the camp.
From early 1942 until late 1944, transport trains delivered Jews to the camp's gas chambers from all over German-occupied Europe.
Around 1.3m people were reported to have died there - but some say the figure could be as high as 2.5m.
