About the museum
Schwarzburg is the ancestral seat of the Counts and later Princes of Schwarzburg; it can be documented since 1123. The medieval castle became a palace in the 16th century and again around 1700; after a fire in 1726 it was restored as a hunting lodge and summer residence. The Kaisersaal building was constructed between 1713 and 1719 from a garden house and served as a hall of fame and ancestors, with portraits of the Roman and German emperors.
After Prince Günther Viktor's abdication in 1918 and the signing of the Weimar Constitution by Friedrich Ebert in Schwarzburg in 1919, the complex initially remained intact. In 1940 its conversion into a Reich guesthouse began, during which large parts of the buildings were demolished; in 1942 the work was halted and the palace fell into ruin. Since then the complex has been gradually secured and opened to visitors; a friends' association works to preserve it.
The centerpiece of the exhibitions is the Princely Arsenal (Fürstliches Zeughaus). It is considered the only surviving free-standing arsenal in Germany and displays a weapons collection of more than 5,000 objects spanning five centuries. There are also exhibitions in the gatehouse and in the Kaisersaal building. Since June 2026 a service area in the main building has been open as well, through which the palace can be entered for the first time since 1942 via its former main entrance.
