Kongsberg Silver Mines
The silver mines of Kongsberg, in Buskerud county in Norway, constitute the largest mining field in Norway, with over 80 different mines. It was the largest pre-industrial working place in Norway, with over 4,000 workers at its peak in the 1770s and supplied over 10% of the gross national product of the Danish–Norwegian union during its 335-year-long history: over 450,000 man-years were expended in the production.
Camp Morton, Svalbard
The coal mining was never as profitable as investors had hoped, and operations had ended by the mid-1920s. Mining of other resources was also difficult. In 1932 the investors sold the Northern Exploration Company to the Norwegian government; its total property included 58 huts. Twenty-seven have survived, and the largest is Michelsenhuset, now known as Camp Morton. It has been restored by the government and is the largest structure at the site. A nearby hut, known as Clara Ville, is available for use by the Longyearbyen snowmobile club. The site also has some remains of mining equipment and the tracks of the mine railway.
