The manor house was first mentioned in 1519 and it has been linked with the Ludens, von Strömfelds, von Münnichs and von Oettingens. The one-storey Baroque main building was completed (on the basis of a middle-age building) in 1736; the building was made longer in the 19th century. The building has kept its two-storey form that it got in the 1950s. The building was renovated in 1997-2000 and is now used by a vocational school.
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.
