From shelter to training gallery
A small part of today's Velsen adventure mine was used as an air raid shelter for the Velsen mine workforce during the Second World War. After the war, it was extended and used to introduce young prospective miners to active mining in a safe environment. This required original machinery, real expansion and experienced miners who familiarized these young men not only with the handling of the equipment, but also with safety devices, signalling systems and mining vocabulary.
