context_page_description: The silver mines of Kongsberg, in Viken 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.
  The silver mines in Kongsberg were in operation from 1623 until 1958. Total production exceeded 1,3 million kg silver.
  The town of Kongsberg houses the Norwegian Mining Museum, which houses collection of silver, tools, and machinery utilised by the miners, engineers, and doctors.
