The city of Falun received its privileges in 1641. By then Falun was already one of the largest cities in Sweden, with about 6000 inhabitants. Soon, however, the importance of the copper mine began to decrease. In 1687, parts of the mine collapsed in a landslide, creating a 100 m deep pit. Even though the mine remained in use for the next 300 years, the production gradually diminished, until it closed down in 1992. The mining area of the Falun Mine has been declared a UNESCO World Heritage Site, which also was the name of the mining company of Falun, is today a part of Stora Enso.
