The National Museum holds and preserves, exhibits and promotes public knowledge about Norway's most extensive collection of art. The Museum shows permanent exhibitions of works from its own collections but also temporary exhibitions that incorporate work loaned from elsewhere. The National Museums exhibition avenues are the National Gallery, the Museum of Contemporary Art, the National Museum, the Museum of Decorative Arts and the National Museum of Architecture. A new National Museum in Oslo will open in 2020 located at Vestbanen behind the Nobel Peace Center.
