It is a very cold place, often -30°C in winter. You can’t get to Norilsk by car or bus because there aren’t any roads. You have to fly or, in summer, arrive by boat. (In winter, the sea turns to ice.) The city has a population of around 180,000. A lot of these people work for Norilsk Nickel, one of the biggest metal companies in the world.

In fact, the average life of an inhabitant of Norilsk is ten years shorter than other Russians.B Punta ArenasPunta Arenas is in the south of Chile, in South America.

The city’s main attraction is a large open-air market. Tourists sometimes come to El Alto to visit the market, but they have to be careful – there is a lot of crime in this region.
