The artcentre was founded in 1968 by World and Olympic champion figure skater Sonja Henie (1912–1969) and her husband, shipping magnate and art collector Niels Onstad (1909–1978).
[2] Their private collection of contemporary art, total 110 images, as well as funds for construction and operation of the centre was donated by the couple in 1961, when the Sonja Henie and Niels Onstad Foundation was created.
In 2003, another extension was made, this time in the form of an annex that extends into the outdoor park, connected to the main building by a passage leading from the lower level.
[5] After being identified in an exhibition catalogue in 2012 by the family of noted French-Jewish art dealer Paul Rosenberg,[6] it was demanded that the HOK return Profil bleu devant la cheminée (Woman in Blue in Front of Fireplace) (1937), a Matisse painting that was confiscated by the Nazis in 1941.
The Einsatzstab Reichsleiter Rosenberg entered the vault in March 1941 to confiscate the art pieces, and after cataloging at Galerie nationale du Jeu de Paume in September 1941, it was designated to the private collection of Hermann Göring.
