Stetten Castle was built around 1200, probably on a predecessor site, although there is no architectural evidence of this. At that time, the Knights of Stetten were vassals of the Hohenlohe family during the time of the Staufer dynasty.
The castle was first expanded around the year 1400. To better protect the inner castle against the increasingly common firearms, a moat was dug in front of the outer bailey. At the same time, a curtain wall with semi-circular flanking towers was erected. In the mid-15th century, the corner towers of the curtain wall were added in another construction phase.
In 1488, the Lords of Stetten became involved in a heated dispute with the Lords of Hohenlohe. During the course of this feud, the Hohenlohe forces besieged Castle Stetten and captured the outer bailey. After tough negotiations and the involvement of various mediators, the disputants peacefully reached an agreement, which is why there was no major damage or destruction of the castle.
The last addition was the baroque 'Outer House' in the outer bailey in 1716, which resembles a palace; this is likely why the present place name came into use. The last major structural alteration took place in 1870. At that time, the inner moat was partially filled, and the gatehouse was modified to allow carriages to enter.
Today Stetten castle is used for senior-friendly living.
References: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.
