I visited Dachau with afriend years ago I had read extensively about the historical period But I learned 2 things I had not known during that visit .
1 Hitler became Chancellor of Germany on 30 January 1933 The camp was set up or started in March 1933, which suggests plans were in hand already.
2 after the war inmates that had lost their familys and there homes due to the Iron Curtain and the demolition of the Ghettos were allowed to stay on in the camp as long as they wanted, The last inmate didnt move out until 1964!!!!
