I will talk about concentration camps of Auschwitz. This is known to Anne frank’s story.
1940/1/25, first concentration camps was built. This is a command by Heinrich Himmler. He was Nazi’s the paramount leader.
1943, 105,000 over Jews were reached there. And 1944, 585,000 over Jews were reached. Many people were killed there. 1945, it was broke up by the soviet army.
All of Jews were very glad. They were released fear.
1979, this was enrolled World Heritage List. Many people visit there.
I think that this history never forget.
