The ironworks at Lövstabruk operated from 1596 until 1926, making it one of the longest-running iron-producing sites in Swedish history. The buildings that housed the hammers, the blast furnaces, and the processing facilities survive in remarkably good condition — enough to understand the physical scale of what was once a significant European industrial enterprise.
The industrial core of the site — the hammer mill, the waterways that powered it, and the ancillary buildings — can be walked around. Some interiors are accessible on guided tours in summer. The workers' houses that line the village lanes give a sense of what life was like in a company-owned community where housing, healthcare, and even a pension were provided by the De Geer family — an early model of industrial welfare that has no real equivalent elsewhere in Sweden at this scale of preservation.
