It takes its toll to climb the immensely high heaps of slag at Liens foundry. From the top you can see Riddarhyttan community and the whirlpools around the foundry. In the blast furnace, which was built in 1847, there is a sound and light show that illustrates the work that was carried out in the foundry. Iron was handled here from the 17th century until 1959. The building has been restored and you can climb up in the charging gallery. From there the whole iron production process was directed. Columns of fire stood high when charcoal flamed up under pressure from the bellows.
An incredible sight!
