The Strafvollzugsmuseum is a small but unusual museum devoted to the history of prisons, punishment, and correctional institutions. Its displays use objects, documents, and reconstructed settings to show how confinement and prison work changed over time.
It is not one of Ludwigsburg's grand palace sights, but it is distinctive enough to reward visitors interested in social history or offbeat museums. The subject matter is sober, and the visit works best as a focused stop rather than a casual family attraction.
