Saxon Hausen concentration camp is located in Oraninburg, a small town 30 kilometers north of Berlin. During World War II, it was the headquarters of Nazi concentration camps in all German-occupied areas.

A three-story tower stands at the entrance of the concentration camp, and the words "labor makes people free" remain on the entrance door. At that time, the prisoner entered the Saxon Hausen concentration camp from the bottom of this signboard.

Entering the gate, there is a big playground where prisoners gather twice a day in the morning and evening. Whether it's stormy or scorching, the prisoners stand here for hours before work every day, waiting for the roll call.

If the count is wrong, everyone must stand at attention until they find someone who hasn't arrived. Sometimes the prisoner will stand all night.

It is reported that the SS often ordered new prisoners to stretch out their arms and squat for hours. Fascists brazenly called it "Saxon salute" and killed countless elderly and infirm prisoners.

Looking from the playground, you can see the walls and watchtowers of the concentration camp. There is still barbed wire in front of the fence in front of the playground. There is a small sign in front of the barbed wire that says "Whoever walks in, shoot". It is said that many prisoners could not bear the torture of the concentration camp and risked their lives to escape through the barbed wire, only to be shot and killed by the guards on the watchtower.
