The estate was first mentioned in 1485, when there was a vassal fortress built by the von Lode family. Later on, the estate belonged to the Kalffs, von Essens and von Stackelbergs.
The Early-Classical main building that had replaced the medieval fortress in the 1770s burnt down in 1911 (in ruins), after which a new luxurious eclectic main building was erected nearby and completed in 1913. Because of its corner towers and granite facing tiles, the building reminds one of a medieval fortress. In 2000–2001, the main building was restored as a hotel and restaurant.
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.
