Mauthausen: Camp of No Return, 9.00pm, Sky History
Streaming on NOW
Those won't be an easy watch.
In August 1938, just west of Vienna, Hitler ordered the construction of the Mauthausen concentration camp, one of the deadliest in history.
Some 200,000 people would be deported there and over 120,000 would perish. The Nazi regime didn't settle for inflicting violence, hunger, and terror onto the prisoners on a daily basis.
It exploited them till their very last breath, by putting them to work on its monstrous war machine.
The hidden traces of the camp, along with archives saved from destruction by heroic prisoners, now reveal the nightmare between a system of concentration camps that blended violence and forced labour.
