The history of Venngarn manor dates to the 12th century. After several owners it was acquired by crown in 1555. Gustav II Adolphus donated Venngarn to Franz von Thurn Berendt and his son sold it to Magnus Gabriel De la Gardie in 1653. The late 17th century was a golden age for Venngarn castle. The present castle was built mainly in 1670 by the architect Jean de la Vallée.
As a chancellor and the leader in Charles XI's regency, De la Gardie was Sweden's most important politicians. Unfortunately for him, due the king's reduction De la Gardie had to return Venngarn later to the crown. Since 1686 the state of Sweden has leased Venngarn castle for several families and purposes. In 1916 a central government institution for alcoholism treatment was established at Venngarn. In 1997 it was sold to its current owners, Wenngarn AB.
There is also a notable chapel in the castle. When the crown took Venngarn 1686, the chapel was completely untouched. None have been added and only a few details have been lost since then. Thus, the chapel one of the country's best preserved church from the Age of Greatness. It was prepared by the De la Gardie, and presumably he also has hired Jean de la Vallee as an architect.

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.
