Those are the shower blocks. They were all set up to be used. You can see where the gas canisters would have been placed. But the Nazis decided it was more efficient to just work and starve and torture people at this particular camp.
This one symbolizes the people who gave in to despair and walked towards the barbed wire. Once they were inside the death zone, the guards could shoot them… or just let them die on the electrified fence.
There was one thing missing that is more heartbreaking than the missing flowers in the ovens. See those triangles? The prisoners all had triangular patches sewed on the sleeves of their striped uniforms. The patches came in different colors. One color meant a political dissident. One meant the prisoner was Jewish or Gypsy. One color meant they were a criminal. One color stood for prisoners of war… there were Russian POW’s held here towards the end of the war. And pink triangles meant the prisoner was a homosexual. If you look closely, some of the triangles in the memorial above are empty. That is because there are two colors missing from the memorial. The green… for professional criminals… and pink… for homosexuals are both missing.
In their infinite wisdom, the people who put this memorial together decide that criminals might have been executed by the state anyway, so they shouldn’t be honored on the memorial… and homosexuality was a criminal offense… so there is no green glass and there is no pink glass.
The artist left a few triangles empty to show what he felt about this oversight.
