Bergkrystallen is the end station on the Lambertseter Line of the Oslo Metro. The area is mainly residential. The station is served by Line 4 (Dark Blue) & Line 1 (Purple),

Bergkrystallen was opened first in 1957 as a Tram Stop but then it was upgraded to a subway station in 1966. Although the subway system was formally opened by the King at Jernbanetorget on 22 May 1966, the King and mayor travelled the line to Bergkrystallen where there was a ceremonial bouquet presentation in front of a large audience.

The building of more residential apartments on the station has met local resistance. In 2007, a proposal was made to build some terraced housing and a kindergarten on the station.
