The Steinsche Schloss is a city palace in the center of Nassau in Rhineland-Palatinate. It served as the seat of the imperial knight family vom Stein. Among other things, the Prussian Minister of Reform Heinrich Friedrich Karl vom und zum Stein grew up there.
The castle's predecessor was a tenth farm, which the von Stein family owned as early as the 14th century. At the beginning of the Thirty Years' War, the now wealthy and influential family relocated from the Stein castle outside Nassau to this complex. In the following centuries, the former courtyard was converted into a castle and expanded.
The main building in the late Renaissance style was completed in 1621. In 1755 two baroque wings were added. Heinrich Friedrich Karl vom und zum Stein commissioned the builder Johann Claudius von Lassaulx to expand the memorial to the Wars of Liberation. An octagonal neo-Gothic tower was added to it in 1815/16. A source [1] indicates for the 19th century that (historically valuable) stained glass from the church of St. Kastor (Dausenau) was "carried away" in the tower.
Today the castle is owned by Steinscher descendants in a female line, the Count of Kanitz. The Cappenberg Castle, in which Freiherr vom and zum Stein lived for many years and which he had chosen as a retirement home, is also owned by the Counts of Kanitz through the inheritance.
