The Engelsberg ronworks are situated just outside the village of Ängelsberg by the shore of lake Ämänningen, approximately 10 kilometres south-east of Fagersta in Västmanland County. The ironworks were founded in 1681 and developed into one of the world’s most modern ironworks of their age. Today, they are the most well preserved ironworks of this type and almost all original buildings and technical equipment are intact. Nordstjernan AB, established in 1890 as a shipping line (Johnson Line), www.nordstjernan.se, preserves, funds and develops the Engelsberg site as the best-preserved ironworks in Sweden.
The original valve factory was recently refurbished into a conference centre at which the Ax:son Johnson Foundation holds regular events and seminars.
