In what prison was Adolf Hitler held in 1924?

The story behind the answer

Landsberg Prison is correct because Adolf Hitler was incarcerated there in 1924 after the failed Beer Hall Putsch. Sentenced to five years, he served about nine months under relatively lenient conditions, during which he dictated much of Mein Kampf to Rudolf Hess and refined a strategy to seek power through legal means rather than violent revolt.

To remember it, link “Landsberg” with “landmark manifesto”: at Landsberg, Hitler produced the book that became a grim landmark in Nazi ideology. The other options are red herrings: Spandau Prison held Nazi leaders after World War II, while Hohenasperg and Ebrach Abbey are historic prisons but unrelated to Hitler’s 1924 confinement.
