Nationalmuseum (or National Museum of Fine Arts) is the national gallery of Sweden, located on the peninsula Blasieholmen in central Stockholm. The museum was founded in 1792 as Kungliga Museet.
The museum collection consists of about half a million drawings from the Middle Ages to 1900, a prominent 17th-century collection of Rembrandt and other Dutch painters, and a collection of porcelain items, paintings, sculptures, and modern art as well. In total the collection amounts to circa 700 000 objects. The museum also has an art library, open to the public and academics.
Nationalmuseum holds the largest collection of portrait miniatures in the world, with more than 5 200 works. The collection features miniatures from many European school's, including works by Nicholas Hilliard, Isaac Oliver, Louis-Marie Autissier among others. A significant portion of works derives from the master collector Carl Fredrik Dahlgren, while the more exclusive works were donated by Hjalmar Wicander, a cork factory owner. Production of bottle corks for the brewery industry provided the basis of his fortune. Wicander also donated funds specifically for additional purchases of miniatures.
