 However, this ended in tragedy, when over 3,000 rather unprepared soldiers perished in the harsh weather conditions in the mountains northwest of Røros.Røros and its people were made famous to Norwegians at the turn of the 20th century by semi-fictional author Johan Falkberget, who told the story of the mining community from the perspective of the hard-tested miners at the bottom of the social ladder.With its authentic wooden buildings, Røros was added to the UNESCO World Heritage Site list in 1980.
