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.
Brønnøysund
In recent years, Brønnøysund has managed to create a certain economic growth. "Fjord Seafood" originated here, as well as the largest limestone mine in Northern Europe and the highest foodstuff production in Northern Norway are examples of entrepreneurship and well-run economy in this somewhat prosperous region. Modern agriculture, hydroponics, the large TTS transport corporation, wood-processing and tourism are the main driving industries.
