Builders working near the site of the Auschwitz Concentration Camp in Poland have found a message hidden by prisoners 65 years ago.Even though, in September 1944, the Second World War was entering its final stages, the group of seven young men could have had no idea if they would survive the horrors of the notorious Nazi camp. Young and capable of hard labour, they were working to reinforce the cellar of a nearby warehouse, so it could be protected from air raids. They hid their note in the hope it would be found by future generations. The warehouse is now a school. Teacher Lucjan Suchanek takes up the story: “The workers found a bottle, and inside there was a sheet with a message saying that this anti-air raid shelter was being built by seven people, six Poles and one French, all aged between 18 and 20. It was written in pencil on a scrap from a cement bag.” More than a million people, mostly Jews, died in Auschwitz, the largest of Adolf Hitler’s death camps. But at least two of those who wrote the note are believed to have survived. It will be put on display at the Auschwitz Museum.
