Røros is a town and municipality in the county of Sør-Trøndelag, Norway.
The town is on the UNESCO World heritage list.
Because of various climatic factors, Røros is one of the coldest places in Norway, (notwithstanding its non-impressive latitude) with -50.4°C in early January 1914, and -50.1°C on January 1st, 2001. This is due to an elevation of more than 600 m and a continental climate (the mild coastal air is blocked by mountains).
During winter, a traditional market called "Rørosmartnan" is organized, that draws many tourists, an average of 60,000-70,000 visitors each year. The market begins on next to the last Tuesday in February and lasts five days.
