Where is the Vigeland installation of sculptures located?

Frogner Park (Norwegian: Frognerparken) is a public park located in the West End borough of Frogner in Oslo, Norway. The park is historically part of Frogner Manor, and the manor house is located in the south of the park, and houses Oslo Museum. Both the park, the entire borough of Frogner as well as Frognerseteren derive their names from Frogner Manor.

The Vigeland installation (Norwegian: Vigelandsanlegget), originally called the Tørtberg installation, is located in the present centre of Frogner Park. It is the name of the arrangement of sculptures and not of an area as such, as the entire park is called Frogner Park. The Vigeland installation in Frogner Park is sometimes referred to as "Vigeland Park," but this name has no official status, is not commonly used in Oslo and is considered inaccurate; the director of Oslo Museum Lars Roede said "Vigeland Park" "doesn't really exist" and is "the name of the tourists," as opposed to "Oslo natives' more down-to-earth name, Frogner Park." The legal name of the entire park in accordance with the Place Name Act (stadnamnlova) is Frognerparken (Frogner Park). The sculpture installation was, as part of Frogner Park, protected under the Heritage Act on 13 February 2009 under the name Frogner Park and the Vigeland installation (Norwegian: Frognerparken og Vigelandsanlegget), enshrining its name Vigelandsanlegget in law.
