Preserved iron-ore mine headframe at Kärrgruvan, Norberg, standing over a 180-metre shaft within a heritage mining landscape.
Kilgruvans lave, formally known as Södra schaktets lave, is the surviving headframe building at the Södra Schakt (Southern Shaft) in the Kärrgruvan district of Norberg, Västmanland. The structure was built in 1902 over a shaft that descends to 180 metres, which is itself older and has carried earlier superstructures. The Kärrgruvan area contains one of the most historically dense iron-ore mining landscapes in Norberg, with workings documented from at least 1440.
Adjacent features include the Maskinhuset (engine house, 1901), Risbergs konstschakt housing Norbergs Gruvmuseum (built 1876), and the open pits of Kilgruvan, Pansargruvan, and Mossgruveparken. The site forms part of Ekomuseum Bergslagen. In July 2025 a collapse occurred in the Kilgruvan open pit immediately adjacent to the lave, and in August 2025 structural damage was identified in the headframe itself.
The building was fenced off pending inspection and remediation.
Iron ore working in the Kärrgruvan area of Norberg has a documented history stretching back to at least 1440 and is part of the broader Norberg mining tradition that reaches back to the early medieval period. The site lies on a rich belt of manganese-bearing iron ore in the northern part of Norberg municipality.
Mining in the immediate area of what became the Mossgruveparken complex was conducted over centuries through open-pit (dagbrott) methods, deepening as extraction technology evolved. The Norbergs gruvmuseum, housed in the building above Risbergs konstschakt — a structure of slag brick and painted timber raised in 1876 over a shaft 114 metres deep — preserves the evidence of the pump systems that kept the surrounding workings free of water. Pumping power was delivered from a waterwheel (Polhemshjulet) several kilometres away via a stånggång (rod transmission system).
Södra schaktet, over which Kilgruvans lave stands, is an older shaft that carried earlier superstructures before the present building was erected. In 1901 the Maskinhuset (engine house) was built to house the machines and steel cables that drove the ore hoist. In 1902 the present lave was raised over the shaft in the construction style of the period. From the lave, ore was transferred to wagons on rails leading to a sorting house (skrädhus), where it was sorted on conveyor belts. Active mining in the Kärrgruvan complex continued until 1981.
After closure, the site was preserved as part of Ekomuseum Bergslagen. The Kärrgruvan gruvmiljö comprises the gruvmuseum, Mossgruveparken, Södra schaktets lave, the Maskinhuset, and numerous surviving open pits and shaft structures. The shaft below the lave is today partially backfilled.
In July 2025 a collapse (ras) occurred in the Kilgruvan open pit immediately adjacent to the Norbergs gruvmuseum building, causing the museum to close temporarily and prompting an underwater robot survey to assess the stability of the piller supporting the museum structure. In August 2025, structural damage — a displaced joint on the southern leg of the lave — was identified in Södra schaktets lave, and Linnévägen alongside the building was closed. An expert in historic structures inspected the building and Länsstyrelsen Västmanland was formally notified. The two incidents were assessed by a geologist as unrelated. The longer-term future of the headframe, noted as one of the last of its kind, was subject to assessment by Länsstyrelsen.
