Lapphyttan is a site of world importance in industrial archaeology and a place where you can go back in time to see an early furnace in action. Archaeological excavations from the 1970s proved this was the oldest site discovered of a blast furnace – the innovation that revolutionised iron making. The site dated to the end of the twelfth century. The discovery changed understanding about the history of the iron industry, showing that blast furnaces were older than people thought and began in Sweden and Germany.
Near the archaeological site is a New Lapphytan – a working reconstruction of the furnace to test and demonstrate the technology. The furnace is built of stone with big timbers around it. There is a dam to store water, a wooden water wheel and leather bellows to keep the fire hot, a roasting pit to prepare the ore, a store for charcoal fuel and two finery hearths for processing the cast iron. The site explains technical skills, the workers, raw materials and finished products. In the middle of summer you can see iron being made. Nearby is a visitor centre, a children’s park, a reconstructed mine for iron ore and the Karlberg homestead museum.
