After the bankruptcy of the Røros Copper Works in 1977, the remaining assets of the company were purchased by, the Ministry of the Environment. Part of the remaining assets comprised the large property surrounding "Smelthytta" (the smeltery) and "Malmplassen" (the ore yard) and the property in the Storwartz mining area. These areas are usually referred to as, State Property. Røros Museum is entrusted with the continuous management and restoration of these properties in association with the Directorate for Cultural Heritage in Norway.
Røros Museum administers the land around "Malmplassen" (the ore yard) and "Slegghaugene" (the slag heaps), the areas around Øvre Storwartz (upper Storwartz) and "Olavsgruva" (Olavís mine). At Nedre Storwartz (lower Storwartz) the asssociation AOF has a leasing agreement with The Ministry of the Environment and also has responsibility for maintenance of the buildings.
Most of the buildings on State Land have a connection to the production of the Copper Works. The buildings comprise workshops, barracks for the workers and different types of factory buildings. In addition, there are many other installations, watercourses, mining shafts and shaft buildings and a 1.4 km long cable-bucket transportation system, which has been fully restored.
All these many different types of installations set a tough challenge to the task of restoration.
