The most northerly city in the world:

Also one of the most polluted:
Nickel ore is smelted on site at Norilsk. The smelting is directly responsible for severe pollution, generally acid rain and smog. By some estimates, 1 percent of global emissions of sulfur dioxide comes from there. Heavy metal pollution near Norilsk is so severe that mining the surface soil is now economically feasible as a result of acquiring high concentrations of platinum and palladium through pollution.
The Blacksmith Institute included Norilsk in its 2007 list of the ten most polluted places on Earth. The list cites air pollution by particulates (including radioisotopes strontium-90, and caesium-137 and metals nickel, copper, cobalt, lead, and selenium) and by gases (such as nitrogen and carbon oxides, sulfur dioxide, phenols, and hydrogen sulfide). The Institute estimates four million tons of cadmium, copper, lead, nickel, arsenic, selenium, and zinc are released into the air every year.
The Russian Federal State Statistics Service named Norilsk the most polluted city in Russia. In 2010, Norilsk produced 1.924 million tons of carbon pollutants, compared to a distant 333 thousand tons of pollutants generated by Russia's second most polluted city Cherepovets.
It's not exactly a tourist destination - non-Russians need special authorisation to visit - but some people still make the effort.
