Gjelleråsen is an area which constitutes part of Oslomarka outside Oslo, Norway.
[1][2] The area is bordered by Skedsmo to the east and Nittedal to the north.
There is also the headquarters of Diplom-Is and the head office of Würth Norge.
In the south of the area, towards Skedsmo, is the former Lahaugmoen military base.
This was used as a historical stopping point for invasions, including that led by King Karl XII in 1716.
