Norilsk is the northernmost city on Earth, and whilst people jump to describe it as being cold and grey, this isolated Russian city is both intriguing and exciting. Its geographical location, for example, is just one of the fascinations people have with Norilsk, located within the Arctic Circle and seemingly cut off from the outside world. No roads head out, so the only way to leave is by train, river or plane, although some of these options are made all but impossible thanks to the harsh Arctic weather for the majority of the year.

Delve into the short but interesting history of Norilsk and you'll uncover further reason to visit what has been dubbed "the most depressing city in the world". The settlement was only established in 1935 as a slave labor camp for workers on the nearby nickel mines. Today, the city is still used as base for paid miners, and the region produces over 20 percent of the world's nickel, making Norilsk's exports total more than two percent of Russia's GDP. Norilsk has also been put on the map thanks to is its unique housing constructions, which appear as rows of aging Lego bricks, packing-in the town's population of 170,000 people into a small space at the foothills of the Putoran Mountains.
