Falun is mostly famous for its copper production, once the most important in Europe and the source of Sweden's wealth and power in the 15th to 18th centuries. Today, production has ceased, and the remains of the mining operations make up one of the country's top attractions. The complex of the Great Copper Mountain makes for a very interesting excursion, and a walk around the Great Pit and a visit to the Mining Museum are definitely recommended. The major activity, however, is a visit to the mine itself. It's a rather cold and wet affair, and you will get a helmet and raincoat, but it's still a great experience to see how the miners actually worked down there. The mining complex is about a 25-minute walk from the city centre, which is a pleasant complement to the industrial part and also contains several components of the WHS, including St. Christine's Church, the large main square, and the Stora Kopparberg Church. The WHS also includes many mining sites outside of Falun (more like a cultural landscape), but the most important sites are in the city itself. Falun is on a direct train line from Stockholm, and should be included in any visit to Sweden.
