Ringstabekk is a district in Bærum, Norway. Named after the local farm, the district is also known for its schools and the sports field. The sports club Stabæk IF originates in the area.
The district originates from the farm Øvre Stabæk ('Upper Stabæk'), one of several farms in the Stabekk area. Antiquities from ancient times, such as axes and arrowheads, have been found there. The farm was owned by Hovedøya Monastery before the Reformation of 1536, and thereafter by the Crown. In 1661 it was registered with a private owner, and a series of owners followed until Jens Ring bought the farm in 1839. The farm was renamed Ring-Stabekk, or Ringstabekk, after Jens Ring. In 1826 it had been registered with three horses, ten cattle and twelve sheep.
In 1851 Jens Ring was behind the construction of "The Castle", a Neogothic brick building, drawn by architect Heinrich Ernst Schirmer. The Castle was a center of bourgeois social life until Ring's death in 1874. The property was gradually parcelled out, and farming ceased in 1895. The last private owner of The Castle was newspaper editor Ola Thommessen, who in 1909 sold it to the state via Hans Konrad Foosnæs. The Norwegian State College for Domestic Science Teachers was established; and between 1921 and 1924 modern school facilities were added to supplement The Castle. Between 1943 and 1945 the facilities were occupied by forces from the Nazi German Oberkommando der Marine. In 1994 the Akershus University College took over and used the school as one of several campuses spread across Akershus. The campus was closed in 2003 as Akershus University College centralized to Kjeller, and in October the same year the property was declared as preserved by the Norwegian Directorate for Cultural Heritage. It is now used for temporary schooling while other municipal schools are being renovated.
