Mõdriku estate (Mödders) was first mentioned in 1470. Over the centuries, it has been the property of various Baltic German families. During the 20th century, it has been used by various schools. The building traces its oldest parts to the 17th century, but has been extensively enlarged and rebuilt both during the 1780's and 1890's.
The manor was the home of several successive generations of the von Kaulbars family, including Russian general and explorer Alexander Kaulbars. An ancestor to him, R. A. von Kaulbars (reputedly a great patriot) put up the column commemorating the French-Russian War of 1812 that is still visible in the manor park.

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.
