The proceeds from the silver mining industry provided a valuable grant for the tight finances of Denmark. Denmark–Norway relies heavily on the silver of Kongsberg to support the ongoing war against Sweden. Precious metals are also becoming more and more important in the Denmark–Norway currency production. Therefore, in order to get closer to the source of raw materials, the 1686 Royal Mint moved from Akershus to Kongsberg. During the Great Northern War, in 1716, the city became the main target of Karl XII’s stay in Norderhof.
