The Mauritshuis museum houses the Royal Cabinet of Paintings which consists of 841 objects, primarily Dutch Golden Age paintings. The collections contains works by Johannes Vermeer, Rembrandt van Rijn, Jan Steen, Paulus Potter, Frans Hals, Hans Holbein the Younger, and others. Probably the most famous painting in Mauritshuis is The Girl with a Pearl Earring (ca. 1665), one of Dutch painter Johannes Vermeer's masterworks. It has been in the collection of the Mauritshuis gallery in The Hague since 1902. The another masterpiece in collection is the Anatomy Lesson of Dr. Nicolaes Tulp painted by Rembrandt van Rijn (ca. 1632).
Originally, the 17th century building was the residence of count John Maurice of Nassau. In 1820, the Mauritshuis was bought by the Dutch state for the purpose of housing the Royal Cabinet of Paintings. In 1822, the Mauritshuis was opened to the public and housed the Royal Cabinet of Paintings and the Royal Cabinet of Rarities. In 1875, the entire museum became available for paintings. It is now the property of the government of the Netherlands and is listed in the top 100 Dutch heritage sites.

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.
