Burg Klein-Zimmern / St. Josephshaus, Water castle and cultural heritage monument in Klein-Zimmern, Germany.
Burg Klein-Zimmern is a water castle and cultural heritage monument near Groß-Zimmern consisting of upper and lower structures sharing a narrow ridge. The complex features a four-story residential tower with defensive walls and a 1966 Canisius Building that houses educational facilities and support programs.
The castle was first documented in 1276 and belonged to the Zimmern noble family from around 1030 onward. It underwent various medieval modifications before losing its defensive role in 1864 when it was converted into a youth welfare institution.
The site became a youth welfare center in 1864 under Bishop Wilhelm Emmanuel von Ketteler, focusing on supporting children and young people in need. This transformation shaped the place as a space dedicated to care and education that continues this mission today.
The site sits on gently rolling terrain with paths allowing exploration of the grounds and outer structures. Note that much of the complex remains an active workplace and educational facility, so interior access may be restricted to certain areas.
During World War II the property served as a prisoner hospital where approximately 500 Soviet prisoners of war died. This tragic chapter is now remembered at the nearby Russian Military Cemetery.
