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.
Quenangen Mining Association
Several mines were established in Kvænangen; the largest were the Edward Mine ("Edwards gruve") and Cedar Mine ("Cedars gruve"). The Edward Mine was the first to be opened. It was located on the Kjækan River ("Kjækanelva"), a few kilometers from the sea. The company built housing for workers at Kjækan. When copper ore was found further up in the mountains, on the Badder River ("Badderelva"), new mines were established there. It was too far for the workers to go up and down everyday, and so the Quenangen Mining Association built temporary housing for the workers near the new mines and introduced five-day work weeks so that workers could visit their families down in the valley on weekends.
