Bunker 1, Gas chamber in Poland
The Red House, known as Bunker 1, was part of the Auschwitz-Birkenau extermination camp.
It served as a gas chamber during the Holocaust, witnessing the mass murder of inmates.
Bunker 1 stands as a stark reminder of the atrocities committed during World War II.
Today, it is part of the Auschwitz-Birkenau State Museum open to visitors for education and commemoration.
Unlike the larger crematoria, this smaller facility was pivotal in the early implementation of genocide at Auschwitz.
