If you have a car, there may be a little bit of Norilsk in its catalytic converter, since about half of the world's supply of palladium is mined there.
A man walks past a Soviet-era housing block near the Nurd Kamal mosque in the arctic Russian city of Norilsk April 4, 2007. Mukum Sidikov's grandfather left Norilsk after surviving the labour camps of Soviet dictator Josef Stalin. Sidikov, caretaker of the world's most northerly mosque, retracted his grandfathers footsteps in search of well-paid work in the Russian Arctic. Now he estimates the city is home to about 50,000 Muslims, just under one quarter of the region's population.
