Originally this place was the seter (mountain dairy farm) of Frogner Manor.
Frognerseteren is the end station of the Holmenkollen Line of the Oslo Metro, located in the Marka section of Oslo. It is the station after Voksenkollen. The line to Frognerseteren was completed on 16 May 1916. The station has two platforms which, like other stations on the Holmenkollen Line, only accommodate two-car trains. The elevation of the station is 469 meters (1,539 ft) above sea level, the highest of all the stations in Oslo.
The area around Frognerseteren has very little population, but is popular for recreation, with a restaurant and hiking trails or, during the winter, skiing. Tryvannstårnet is also within walking distance although Voksenkollen station is slightly closer.
Lowry took the tram there in 1931, later describing it to Jan Gabrial in a letter dated Summer 1933; "& when you see a tram come along with Frognarsaeteren on its forehead, take it, pay 90 ore I think it is, go all the way; it will take you up a mountain which is just the best thing in the world & there's a restaurant up there where they speak German for you." (Collected Letters Vol. 1 Pgs. 130-131). Dana Hilliot recalls a boomerang he had there (Ultramarine Pg.18).
