Falun Mine (Swedish: Falu Gruva) was a mine in Falun, Sweden, that operated for a millennium from the 10th century to 1992. It produced as much as two thirds of Europe's copper needs[1] and helped fund many of Sweden's wars in the 17th century. Technological developments at the mine had a profound influence on mining globally for two centuries.[2] Since 2001 it has been designated a UNESCO world heritage site as well as a museum.
