Økern was a farm in the former municipality of Aker, Norway, and is currently a district in the borough of Bjerke in the city of Oslo.
It includes the neighborhoods of Refstad, Risløkka, Brobekk, Nordre Hovin, Aker Sykehus, Bjerkebanen, and Økern Senter.
[1] Among the owners from the 17th century onwards were Ulrik Frederik Gyldenløve (from 1679), Lauritz Jacobsssøn Falch, Paul Peterssøn Vogt, Ole Christopher Wessel, Peter Collett and Ludvig Mariboe (who lived at the farm until his death in 1841).
[4] In the 19th century the farm was split off into several smaller units, and from 1910 onwards small residential houses were built in the northern part of Økern.
[1] Central participants in the development of Økern in the 1950s were architect Gunnar Schultz and building contractor Nils Stian Stiansen.
