Nationalmuseum is the national gallery fine arts of Sweden, located on the peninsula Blasieholmen in central Stockholm. The museum's operations stretch far beyond the borders of Blasieholmen, including the National Portrait Gallery collection at Gripshom, the Gustavsberg porclain museum, several castle collections and the Swedish Institute in Paris (Institut Tessin). In the summer of 2018, Nationalmuseum Jamtli opened in Östersund to exhibit parts of the collection in the north of Sweden. The museum's benefactors include King Gustav III and Carl Gustaf Tessin.
