Rear view - For nearly 100 years, from 1829 to 1924, Colditz was a sanatorium, generally reserved for the wealthy and the nobility of Germany. The castle thus functioned as a hospital during a long period of massive change in Germany, from slightly after the Napoleonic Wars destroyed the Holy Roman Empire and created the German Confederation, throughout the lifespan of the North German Confederation, the complete reign of the German Empire, throughout the First World War, and until the beginnings of the Weimar Republic. Between 1914 and 1918, the castle was home to both psychiatric and tuberculosis patients, 912 of whom died of malnutrition. The castle was home to several notable figures during its time as a mental institution, including Ludwig Schumann, the second youngest son of the famous composer Robert Schumann, and Ernst Baumgarten, one of the original inventors of the airship.
