The Steinsches Schloss is a town palace located in the center of Nassau. It served as the residence of the noble family vom Stein and was, among others, where the Prussian reform minister Heinrich Friedrich Karl vom und zum Stein grew up.
The predecessor of the castle was a tithing farm (Zehnthof), which the vom Stein family had owned since the 14th century. At the outset of the Thirty Years' War, the now prosperous and influential family relocated their seat from the Steinsche Burg outside Nassau to this complex. Over the ensuing centuries, the former farm was transformed and expanded into a castle.
By 1621, the main building was completed in the style of Late Renaissance. In 1755, two Baroque wings were added. Heinrich Friedrich Karl vom und zum Stein commissioned the Wiesbaden architect Christian Zais and later, in 1818, the master builder Johann Claudius von Lassaulx for an expansion to commemorate the Wars of Liberation. In 1815/16, an octagonal Neo-Gothic tower was added. A source indicates that during the 19th century, stained glass windows from the St. Kastor Church (Dausenau) were 'relocated' to the tower.
Following preliminary investigations in the years 2011-2012, the tower was extensively restored with funds from the state of Rhineland-Palatinate by 2018. In the ground floor, the marble baths intended for ritual cleansing before entering the memorial were restored, and a chapel originally planned there was established after 200 years. The Baron's study on the middle floor, with its walk-in library shelves, and the cult site on the upper floor, with sculptures of the three monarchs Friedrich Wilhelm III, Franz I, and Alexander I by Christian Daniel Rauch, were returned to their original condition.
The castle is owned by the female descendants of the vom Stein family, the Counts of Kanitz. The Castle Cappenberg, where Baron vom und zum Stein lived for many years and which he chose as his retirement residence, is also owned by the Counts of Kanitz through inheritance.
The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
