front of the main buildings is also a sundial built for Wegner. Today, the manor buildings are occupied by Oslo City Museum. Outside the manor buildings, there is also a café opened in 1918 (Frogner Park Café) and a restaurant opened in 1960 (Herregårdskroen, "the Manor House Restaurant"). Vigeland installation – the sculptures in Frogner Park The Vigeland installation (), 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 (), enshrining its name Vigelandsanlegget in law. The sculpture area in Frogner Park covers 80 acres (320,000 m2) and features 212 bronze and granite sculptures, all designed by Gustav Vigeland. The Bridge was the first part to be opened to the public, in 1940. The Bridge forms a 100 metre (328 ft)-long, 15 metre (49 ft)-wide connection between the Main Gate and the Fountain, lined with 58 sculptures, including one of the park's more popular statues, Angry Boy (Sinnataggen). Visitors could enjoy the sculptures while most of the park was still under construction. At the end of the bridge lies the Children’s Playground, a collection of eight bronze statues showing children at play. Most of the statues in the park are made of Iddefjord granite. Originally designed to stand in Eidsvolls plass in front of the Parliament of Norway, the bronze Fountain (Fontenen) is adorned with 60 individual bronze reliefs, and is surrounded by an 1800 square metre black and white granite mosaic. The Vigeland installation's granite and wrought iron Main Gate also serves as the eastern entrance to Frogner Park from Kirkeveien. From there an long axis leads west through the Bridge to the Fountain
