placed at the disposal of the Oslo City Museum. Oslo City Museum In the main house at the Frogner Manor, the local historical museum of the City of Oslo is located. The museum gives an impression of the capital city's historical development. Frogner Park The private garden surrounding the manor house was historically much smaller. After Oslo municipality acquired the estate, much of the remaining agricultural land was turned into a public park, the Frogner Park, with Gustav Vigeland's sculpture arrangement (Vigelandsanlegget or the Vigeland installation) erected in the centre from 1928 to 1943. In 1914 the area was the site of the 1914 Jubilee Exhibition. On the outskirts of Frogner Park is Frognerbadet (Frogner Baths), which opened in 1956. Old Frogner Stadium opened in 1901 and was the city's main arena for skating. In 1914 the current Frogner Stadium was built right next to the old stadium. At the site of the old Frogner Stadium, there are now tennis courts. Frognerseteren The seter (mountain dairy farm) of Frogner was situated near the summit of the Holmenkollen hill north of Oslo, and included parts of the Nordmarka forest. The name is still preserved in the terminal Frognerseteren station of the suburban Holmenkoll Line, opened in 1898 and extended in 1916. Frognerseteren and the forest was split from Frogner Manor when Benjamin Wegner sold the manor but kept Frognerseteren in 1848. Wegner's heirs sold it to Thomas Johannessen Heftye in 1864, and his heirs sold it to the municipality in 1889, thus making it the first forest owned by Oslo municipality. Etymology The Norse form of the name was Fraunar (plural form). The name is probably derived from the word frauð 'manure' - and then with the meaning 'fertilized fields'. See also Frogn and Tøyen).
