Krongods is an estate owned by the royal power which brought rental income to the crown before it came into private hands from 1838. The Solbakken farmstead was sold out in 1867 and was later the summer residence of the painter Hans Gude.
Here was formerly Oksenøya farm, Scandinavia's largest horticulture plant built by A. F. Klaveness. The estate was designed by Magnus Poulsson, who also designed Oslo City Hall together with Arnsteing Arneberg, and consisted of 10 greenhouses with, among other things, 70,000 chrysanthemums. The gardening business ceased in 1998.
During World War II in late 1941, the Germans set up a secret camp on the site for Russian prisoners of war. In May 1944, the camp was placed under the Grini prison camp, under the Luftwaffe. From then on, Norwegian and German prisoners were also placed in the camp, which consisted of twenty 12-sided tents, built up of plywood sheets of around 5 m² with an oven in the middle of the room and three small windows. Here 15 men lived in each, in two bunk beds that took up about half of the floor space, with eight places in the lower one and seven in the upper one. Over the spring, the camp was expanded to 33 tents, with a total of 400 prisoners from Grini. The prisoners worked on the airport, in the winter, among other things, treading the runway after snowfall.
After the war, the farm was bought by the State in connection with the creation of the Fornebu civil airport. In 1997, the foundation stone for Norske Skog's main building was laid where the camp was located, a building which two years later received Bærum municipality's aesthetic award.The office premises were placed so that the new and older buildings together form a yard. There is also a relationship between the new and old buildings in dimensioning, especially in height, and choice of materials. For example, Poulsson's spruce barn panel, which has been treated with iron vitrol and carbon black, has been repeated.
Norske Skog was founded in 1962 and was one of the world's largest producers of newsprint and magazine paper. The group had at most 13 factories in 10 countries worldwide, but went bankrupt in 2017 and was acquired by an investment company.
Today, a bird reserve has been established in Storøykilen between Oksenøya and Storøya, where 257 bird species have been recorded, as well as around 700 plants.
