Auschwitz-Birkenau visit.

The Auschwitz concentration camp (Konzentrationslager Auschwitz) was a complex of over 40 concentration and extermination camps built and operated by Nazi Germany in occupied Poland during World War II and the Holocaust. It consisted of Auschwitz I, the main camp (Stammlager) in Oświęcim; Auschwitz II–Birkenau, a concentration and extermination camp in Brzezinka three kilometers away; Auschwitz III–Monowitz, a labor camp in Monowice created to staff an IG Farben synthetic-rubber factory; and dozens of other subcamps.

The Auschwitz-Birkenau Memorial and Museum - Former German Nazi Concentration and Extermination Camp (Polish: Państwowe Muzeum Auschwitz-Birkenau w Oświęcimiu) is a memorial and museum in Oświęcim (German: Auschwitz), Poland, which includes the German Nazi concentration camps Auschwitz I and Auschwitz II-Birkenau.

The Women's Orchestra of Auschwitz (Mädchenorchester von Auschwitz; lit. "Girls' Orchestra of Auschwitz") was formed by order of the SS in 1943, during the Holocaust, in the Auschwitz II-Birkenau extermination camp in German-occupied Poland. Active for 19 months—from April 1943 until October 1944—the orchestra consisted of mostly young female Jewish and Slavic prisoners, of varying nationalities, who would rehearse for up to ten hours a day to play music regarded as helpful in the daily running of the camp.

The Theresienstadt family camp (Czech: Terezínský rodinný tábor, German: Theresienstädter Familienlager), also called the Czech family camp, existed at BIIb section of Auschwitz II-Birkenau concentration camp from 8 September 1943 to 12 July 1944. The prisoners, most of whom were Czech Jews, had been deported from Theresienstadt concentration camp via seven transports in September, December, and May.

On the night of 5 April 1944, Siegfried Lederer, a Czech Jew, escaped from the Auschwitz concentration camp wearing an SS uniform provided by SS-Rottenführer Viktor Pestek. Because of his Catholic faith and infatuation with Renée Neumann, a Jewish prisoner, Pestek opposed the Holocaust. He accompanied Lederer out of the camp, and the two men traveled together to the Protectorate of Bohemia and Moravia to obtain false documents for Neumann and her mother.
