Granbergsdal Ironworks

Granbergsdal Ironworks (Granbergsdals bruk) is an ironworks, blast furnace, in Granbergsdal, a village in Karlskoga Municipality in Sweden, 10 km (6 mi) north of central Karlskoga.

History
Designated as a listed building in 1986, the ironworks benefits from cultural and historical protection.

Founded in 1642 by Mårten Eriksson, Granbergsdal Ironworks emerged in response to the increased demand for iron during the tumultuous period of the Thirty Years' War. However, operations at the ironworks ceased in 1925.

The 2023 renovation of the works was delayed in May due to the discovery of a previously unknown standing historical house.
