3. Manpupuner, Russia
All that remains of a once mighty mountain range eroded by 200 million years of rain, these precarious pillars are located just below the Arctic Circle on the far side of the Ural Mountains, and climb between 30 and 42 metres into the sky. Sacred to the local Mansi people, who believed they were giants petrified by the Gods, the rocks were named one of the Seven Wonders of Russia in 2008, alongside Lake Baikal, the Peterhof Palace, and St Basil’s Cathedral.
