The Eldorado was the name of multiple nightclubs and performance venues in Berlin before the Nazi era and World War II.

"Cross-dressing" was tolerated on the premises, though for the most part legally prohibited and/or sharply regulated in public (and to an extent in private) at the time.

As women's incomes were then on average much lower than men's, male spectators with money to spend were explicitly welcome, and it was not uncommon for there to be sex workers present to offer their services.

Criminalization made researching, speaking, or writing about queer realities a legal risk during the first decades following WWII, not only in Germany.

[5] The performances at the club were diverse and included effeminate men dancng whilst dressed in women's clothing, and a man singing Parisian-sounding songs in a high-pitched soprano.

[2] Hitler was appointed chancellor in January 1933, and shortly afterward the Nazis seized the club space at Motzstraße 15 to use it as the Sturmabteilung (SA) headquarters.

[2] The club was written about in the German nonfiction book Ein Führer durch das lasterhafte Berlin: Das deutsche Babylon 1931 (English: A Guide Through Licentious Berlin: The German Babylon 1931), authored by Curt Moreck (pseudonym for Konrad Haemmerling).

Largely overlooked in the telling of Eldorado's LGBT history is the building at (former) Motzstraße 15's role in the West German beginnings of the second gay and lesbian movement.
