Norberg is a locality and the seat of Norberg Municipality in Västmanland County, Sweden with 4,518 inhabitants in 2010. Most known is the Norbergfestival which is Scandinavias biggest electronic music festival, organized in an old iron mine. Norberg consists of two large parts, the actual Norberg in the south and Kärrgruvan (Marsh Mine) in the north, along with smaller settlements scattered around the area.
Iron-making in Norberg can be traced back to the 500s, but the area has been populated since the Nordic Stone Age.
The blast furnace plant at Lapphyttan, probably originates from 11 - 1200's (currently under reconstruction elsewhere), shows the beginning of the mining community that grew up in Bergslagen. In the Middle Ages, Norberg was a marketplace where mountain men in the surrounding districts gathered.
The oldest preserved buildings in Norberg are in Norbergsån, the area around Norberg church with farms that originate from the Middle Ages, while many current buildings are from the 1700s. The oldest parts of Norberg's church, including the vaults, date from the 13th century. The interior was changed after a big fire in 1727 and the church tower was rebuilt in 1904. In the cemetery is a bone chamber from the 1700s.
Despite an extensive fire in the mid-1700s, one can still see the original settlement pattern in central Norberg with booths, laundries and a wash-house along the river, while farm houses and residential buildings are nearby.
In the 1970s, raw molten iron was transported by rail from the blast furnaces at Spännarhyttan to the steelworks at Surahammar. Spännarhyttans blast furnace was shut down for good in 1981.
