Norilsk (Russian: Нори́льск nah-REEL'SK) is a large city in Taymyria. Because of its strategic importance, Norilsk is a closed city and special permission is needed for travel, which will likely be denied unless you have a really good reason. Norilsk is the second largest city above the Arctic Circle; Murmansk is the largest. With a population of 210,000, it is also the northernmost city with a population over 100,000 inhabitants.
Norilsk was founded due to the existence of a rich deposit of non-ferrous metals including nickel, cobalt, copper, platinum, and palladium. Founded before World War II, Norilsk and its mines and industrial plants, as well as a railway connecting the city with the port of Dudinka, were built with a large-scale use of convict labor from gulag prisoners.
Norilsk Nickel is the largest producer of non-ferrous metals in the world, accounting for 38% of worldwide production of palladium and 22% of worldwide production of nickel, a key ingredient in stainless steel. Some of the locally mined ore is smelted into metals at the local refinery. More ore, after some enrichment, is shipped by rail to Dudinka; from there it is sent by icebreaker-led ships to Murmansk, and eventually to the copper and nicker refinery at Monchegorsk, whose own ore has long been exhausted.
As a result of the smelters, Norilsk is the most polluted city in Russia and is one of the most polluted cities in the world, usually covered in chemical smog. The life expectancy in Norilsk is one of the lowest in Russia and its cancer rates are one of the highest.
The yearly average temperature is in Norilsk is −9.8°C and temperatures usually hover around −40°C in the winter.
Most inhabitants of the city were transplants as a result of the high salaries and abundant opportunities offered by the mining industry.
Buses are plentiful and go everywhere as a result of the harsh winter climate. Taxis are reasonably priced.
Norilsk has several grand buildings in the center; however, it mostly consists of drab commieblocks. Surrounding the city are vast areas of decaying industrial sites which are both depressing and fascinating at the same time.
