District of Vinderen

Vinderen was district 23 with 19 371 inhabitants (1999) on 10.3 km2. It was an elongated district from Majorstuen to Voksenkollen on both sides of the Holmenkoll metro. The map of the district of Vinderen clearly shows that it was the Holmenkoll metro that laid the foundation for the settlement. This began in earnest at the turn of the century 1900 after the railway had opened from Majorstuen to Besserud in 1898. Three of the most famous places in the Vinderen area are outside the district: Holmenkollbakken, Frognerseteren and Tryvannstårnet.

The district had some old farmhouses on the old seabed: Ris, Grimelund, Vinderen, Borgen and Holmen. With the Holmenkollbanen railway, the settlement came above the marine border (221 m above sea level) and is at Voksenåsen highest in the city, just over 500 m above sea level. The buildings throughout the district from Frøen to Skådalen and Lillevann consist of small wooden houses, although since the 1990s there has been a densification of the area with low blocks.

Several health institutions were located in the Vinderen district: Rikshospitalet, Diakonhjemmet, Vinderen Psychiatric Clinic (under Aker Hospital) and the private Volvat Medical Centre. The district have two business centres, Slemdal and Vinderen; the latter was also home to the district administration.

The Disctrict of Vinderen have the lowest population density in Oslo after the districts of Søndre Nordstrand and Ekeberg-Bekkelaget, and the proportion of young adults and the elderly was lower than the city average. Population growth in the 1990s was much higher than elsewhere in the city due to new peeople moving in. Consequently, there were also relatively many children of school age.

The area stretches from Frøen to Holmenkollen. Around 550 residents in Marka and Sørkedalen receive their services from the district. The name refers to the oldest farm name in Oslo, Aker, which was located by Gamle Aker church and dates back to the Iron Age.

The district of Vinderen got its name from the farm Vinderen, the main building is still located at Tunfaret 11. Vind is probably an older name for Sognsvannsbekken and comes from the "windy", winding stream, the delta just below Vinderenfossen close to the farm. The ending -ern is probably a suffix without meaning (as in Stav-ern and Blind-ern), but in old sources the farm name was most often written Winderen or Vinderen.

The district of Vestre Aker takes its name from the former shire (municipality) of Aker, which was merged with Oslo on 1 January 1948. It was in turn named after the oldest farm in the shire, Aker, which was located by Gamle Aker church. Bydel Vestre Aker is the northwesternmost part of the former Aker shire. Aker herred was originally one ecclesiastical parish, which in 1861 was divided into two, Vestre Aker and Østre Aker. In 1906, Vestre Aker was again divided into two parishes, Vestre Aker and Ullern, which were administrative parishes until 1948.
