Røros Mining Town was inscribed in the World Heritage List under criteria (iii), (iv) and (v) in 1980. In 2010, the World Heritage area was extended to include the mining areas and the agricultural landscapes around Røros Mining Town, the Femundshytta melter and the “winter-route”. The area called the Circumference, granted to the mining enterprise by the Danish-Norwegian Crown in 1646, was added as a buffer zone: 2 national parks, Femundsmarka and Forollhogna, and parts of three Sámi reindeer husbandry districts are located within. Because of the lack of written and tangible sources of Sámi practices, the recognition of Sámi environmental knowledge and customary landscape management strategies have been limited in the World Heritage site narrative. Since the extension, a process has started at the management level to include Sámi culture into the interpretation of the site, with a focal point on the Røros museum, which also functions as Røros and the Circumference World Heritage centre.
