Auschwitz-Birkenau Memorial and Museum

The largest and most systematically lethal of the Nazi German concentration and extermination camps and the site that has come to represent the Holocaust in its entirety — Auschwitz-Birkenau, where approximately 1.1 million human beings were murdered between 1940 and 1945, is the most morally significant single heritage site on Earth, the place that compels every visitor to confront what industrialised state murder looks like when its physical evidence is preserved.

At a glance

Auschwitz-Birkenau (UNESCO WHS 1979; the most morally unambiguous single heritage inscription in UNESCO history: inscribed under the extraordinary title “Auschwitz Birkenau: German Nazi Concentration and Extermination Camp (1940–1945)” — the only UNESCO World Heritage Site explicitly named after a perpetrator nation and an atrocity — the most precisely described single crime in any UNESCO inscription; the most deliberately named single WHS title in the history of the programme (the title was chosen to ensure that no ambiguity remained about who built and operated the camp); the complex (the main camp Auschwitz I (the original camp; opened June 1940; 28 brick buildings; the Arbeit macht frei gate) and Auschwitz II-Birkenau (opened 1942; 3 km from Auschwitz I; the main extermination complex: the largest concentration and extermination camp ever built; 300 wooden and brick barracks; 4 crematoria with gas chambers; the capacity to gas 4,756 people per day (the most precisely calculated killing capacity of any facility in the history of mass murder))); the victims (approximately 1.1 million people were killed in the complex — the most precisely estimated single Holocaust death toll: approximately 1 million Jews (the most single-site Jewish death toll in the Holocaust); 70,000–75,000 Polish political prisoners; 21,000 Roma; 15,000 Soviet POWs; 10,000 others)).

Key facts

The industrial system of murder: the most precisely documented single system of mass killing in history — the Birkenau (Auschwitz II) extermination apparatus (the most industrially organised single killing facility in the Holocaust: the 4 crematoria with integrated gas chambers (the most precise single killing schedule in any concentration camp: each gas chamber could hold 2,000 people; the killing time was 15–20 minutes; the combined capacity was approximately 4,756 people per 24 hours — the most precisely calculated killing rate in any human enterprise of murder); the rail line (the most consequentially extended single railway spur in the history of the Holocaust: the rail line was extended from the main Auschwitz station 2 km into the Birkenau camp in 1944 — the most precisely timed single logistical improvement in the Holocaust: the extension was made specifically to accelerate the deportation and killing of Hungarian Jews (437,402 deported from Hungary in 56 days in May–July 1944 — the most rapidly executed single mass deportation in the Holocaust); the Sonderkommando (the most psychologically tormented single group in the history of the Holocaust: the Jewish prisoners forced to work in the crematoria — the most precisely documented group of forced participants in mass murder; the Sonderkommando revolt of 7 October 1944 — the only armed uprising within the crematorium complex — the most courageous single act of resistance in the history of the Auschwitz camp))
The evidence and the archives: the most extensively documented single crime in history — the documentation (the most comprehensive single archival record of a perpetrator bureaucracy in the history of genocide: 65 km of documents in the Auschwitz-Birkenau State Museum archive — the most precisely measured single paper archive of a crime in world legal history; the evidence base for the Nuremberg Trials (the most legally consequential single historical trial in the history of international law) included the Auschwitz documentation as the most precisely evidenced single count of murder in the history of criminal prosecution); the exhibits (the most affecting single museum exhibition in the world: the Auschwitz I museum buildings contain the property of the victims (the shoes (80,000 pairs of shoes on display — the most precise single material evidence of an individual human life in any memorial museum in the world), the hair (approximately 2 tonnes of human hair (the most viscerally undeniable single physical evidence of mass murder in any World Heritage Site), the spectacles (the most individually humanising single exhibit in any Holocaust museum: each pair of glasses represents a person who wore them), the suitcases (the most poignant single evidence of the victims’ expectation of survival: suitcases labelled with names and addresses — the most precisely personalised single evidence of those who did not know they were going to die))
Witold Pilecki — the most courageous act of voluntary imprisonment in war history: the most remarkable single individual act of resistance in the Holocaust — Witold Pilecki (the only known person to voluntarily allow themselves to be arrested by the Nazis and sent to Auschwitz (1940–1943) — the most courageous single act of voluntary self-imprisonment in the history of warfare; Pilecki organised the Auschwitz resistance movement from inside the camp; escaped March 1943; submitted reports to the Polish Home Army and to the British intelligence services detailing the extermination process — the most precisely evidenced early warning of the Holocaust available to Allied governments; the British intelligence response to Pilecki’s reports was dismissed as exaggeration — the most consequentially disbelieved single intelligence report in the history of the Holocaust; Pilecki was executed by the post-war Communist Polish authorities in 1948 — the most unjust single post-war execution of a resistance hero in Polish history)

History

The camp’s origins (Auschwitz I was established in June 1940 by the SS on the orders of Reichsführer-SS Heinrich Himmler (the most consequentially ordered single camp establishment in the history of the Holocaust) in a former Polish Army barracks in the town of Oświęcim (German: Auschwitz); initially a political prison for Polish political prisoners and POWs; the escalation to mass killing (the most precisely dated escalation in Holocaust history: the mass killing of Jews began at Auschwitz-Birkenau in 1942 as part of the “Final Solution to the Jewish Question” (the Wannsee Conference: 20 January 1942 — the most bureaucratically organised single meeting in the history of genocide); the Hungarian deportations (May–July 1944: the most rapidly executed single mass deportation in the Holocaust (437,402 people in 56 days): the most precise single evidence of the speed achievable by the Nazi killing machine at its 1944 peak)); the liberation (27 January 1945: the Red Army liberated Auschwitz — the most precisely celebrated single liberation date in the history of the Holocaust; adopted as International Holocaust Remembrance Day by the United Nations in 2005 — the most globally institutionalised single memorial date in the history of genocide); UNESCO WHS 1979.
