Engelsberg is one of the best-preserved ‘bruks’ (ironworking villages) in Sweden. Iron was made in the community from 1681 and the manor house in the French style was completed in the 1740s. The blast furnace, of earth and timber construction, dates in its present form from 1779, and worked until 1919, when it was producing about 10 tonnes a day. The forge building was rebuilt in 1845 to accommodate the Lancashire Forge process. Two summerhouses near the mansion are constructed of blocks of blast furnace slag. Many workers’ houses of the 18th and 19th centuries remain. The Bergslagen Ecomuseum administers the ironworks and the nearby Angelsberg oil refinery.
