Krumbach Castle was constructed as a fortress in the 11th century. In 1192 Gerhardus de Chrumpach was mentioned in documents for the first time. The fortress was destroyed by the Magyars in 1260. It was later owned for over 200 years by the family of Pálffy von Erdöd.
Sold to an Austrian lawyer 1875, the castle changed private owners several times. It was converted into a hotel in 1993 and owned by the Austrian investor Mirko Kovats and his Artis Hotel Group as of 2009. Since 2020, it has operated as Schloss Krumbach International School, a private school with boarding.
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.
