The Memorial and Information Point for the Victims of National Socialist Euthanasia Killings serves as a tribute to the victims of the Nazi's involuntary euthanasia program, Aktion T4, under which over 70,000 people were murdered between 1940 and 1941. Although the program officially ended in August 1941, the killings persisted in state-run institutions until Germany's surrender in 1945, resulting in an estimated death toll of around 300,000.

Eichmann's office. The Reich Security Head Office Referat IV B4, commonly known as RSHA IV B4, was a sub-department of Germany's Reich Security Head Office and the Gestapo during the Holocaust. Initially known as Eichmannreferat IV D4 and later as Judenreferat, SS-Obersturmbannführer Adolf Eichmann led it. The department was chiefly responsible for "Jewish affairs and evacuation" in German-occupied Europe, particularly the deportation of Jews from outside Poland to concentration or extermination camps.

Berlin was home to Germany's largest Jewish community before the rise of the Nazi regime. The Jewish population of Berlin in 1933 was approximately 160,000, making up over 32% of all Jews in Germany. However, due to Nazi persecution and the subsequent emigration, this number fell to about 80,000 by 1939. The Jews in Berlin, like those throughout Germany, faced increasing discrimination, persecution, and violence, especially after the Nazis came to power in 1933.

The Gleis 17 Memorial, located at the Grünewald train station in Berlin, stands as a sombre reminder of the Holocaust. It marks the platform from which over 50,000 Jewish Berliners were deported to concentration and extermination camps between 1941 and 1945.

The SS Main Economic and Administrative Office (German: SS-Wirtschafts- und Verwaltungshauptamt; SS-WVHA) was a Nazi organisation responsible for managing the finances, supply systems, and business projects of the Allgemeine-SS, a main branch of the Schutzstaffel (SS). The SS-WVHA also played a crucial role in the operation of concentration camps and was instrumental in the implementation of the Final Solution through its subsidiary offices, such as the Concentration Camps Inspectorate and SS camp guards.

The German Society for Racial Hygiene (Deutsche Gesellschaft für Rassenhygiene) was a German eugenic organisation founded on 22 June 1905 by physician Alfred Ploetz in Berlin. The society aimed to promote the idea of a "healthy and blooming, strong and beautiful life" through selective reproduction and sterilisation, emphasising the purity of the Nordic race. The society became inactive after World War II.

The Wannsee Conference was a meeting of senior government officials of Nazi Germany and Schutzstaffel (SS) leaders, held in the Berlin suburb of Wannsee on 20 January 1942. Organised by the director of the Reich Security Main Office, SS-Obergruppenführer Reinhard Heydrich, the conference aimed to ensure the cooperation of administrative leaders of various government departments in the implementation of the Final Solution to the Jewish Question.
