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.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
