Norberg och lapphyttan

Norberg

Norberg is the only town in Norbergs municipality and consists of two main parts, the actual Norberg in the south and Kärrgruvan in the north.

lapphyttan

Lapphyttan in Norberg, Sweden, may be regarded as the type site for the Medieval Blast Furnace. Its date is probably between 1150 and 1350. It produced cast iron, which was then fined to make balls of iron known as osmonds. Osmonds occur in English Customs records in the 1250s and seem to be alluded to in a commercial treaty with Novgorod in 1203. Furnaces of this type have also been identified in Mark (Märkische Sauerland) in Westphalia and north of the Schwäbische Alb both in Germany.
