Rydboholm Castle (Rydboholms slott) dates back to the Middle Ages. The castle, with the three interconnected wings around an open courtyard, dates from the 16th century. The main building was built in 1548. The castle was reconstructed during the 18th century. Southwest of the castle is a large park in English style from the early 19th century, built by Magnus Fredrik Brahe.
From the 15th century, Rydboholm was the property of members of the Sture family, followed by the Vasa dynasty and later the Brahe family. According to some sources Gustav I of Sweden, who was King of Sweden from 1523 until his death, was born at Rydboholm Castle. From 1520, it belonged to his sister, Margareta Eriksdotter Vasa.

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.
