Inside the Incredible Secret Mission to Climb Europe's Tallest Building

Russian adventurers dressed like construction workers to reach the ice-covered pinnacle of Mercury City, which is taller than London's Shard.

Here's one advantage that illegal skyscraper-scaling has over mountaineering: Unlike Everest, which give or take a few inches remains the same height for ages, the targets for urban climbers continually get taller and more insane.

Or psychotically monkey bonkers, if we're talking about the crew that recently clambered up Mercury City in Moscow. At about 1,110 feet high, the still-unfinished office and residential tower recently stole the title of Europe's tallest building from London's Shard. But that wasn't enough for the scurrying squirrels that inhabit Moscow's concrete jungle. They wanted to touch the wobbling apex of the spire – the end of a rooftop construction crane that hovers 1,214 feet above the cold, hard ground.
