The mining complex, to the west of town at the top end of Gruvgatan, contains various sights. Most dramatic is the Stora Stöten (Great Pit), a vast hole caused by a major mine collapse in the 17th century. By some miracle, the miners were on holiday that day and no one was harmed. There are lookouts around the crater edge, and numerous mine buildings including a 15m waterwheel and shaft-head machinery. Opening hours are complicated – check the website for details. Take bus 709.
