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.
Foundations in Norway
There are approximately 7,600 foundations in Norway. Based on a total capital of nearly 100 billion crowns, foundations possess and control assets of estimated 200–300 billions. They constitute a small but economically important contribution to Norway's social and cultural life and to sports, education, and science. Norwegian foundations partly employ and partly engage approximately 35,500 individuals. Most foundations are located in the capital Oslo (the biggest city) and Bergen (the second biggest city). However, city-based foundations often cover most or all parts of the Kingdom.
