Nobel bought the whole area of Vinterviken in 1865. Due to safety issues he had to move his research lab and his factories from central Stockholm to Vinterviken which was surrounded by cliffs and therefore more suitable for the dangerous experiments. Gradually, Nobel developed the area by constructing a local rail-road, a harbour, testing grounds for exploring dynamite and housing for factory workers. Dynamite used to be manufactured in this area until 1921 but Nobel's factory remained working until the 1980s.

Since 1974 Vinterviken belongs to Stockholm city and has been converted from an industrial place to a public recreational area.The former nitroglycerine and dynamite factory area is now a big lawn, popular for recreational activities in summer.
