Looking up from the base of the Ping An International Finance Centre building in Shenzhen, China, is a harrowing experience. Currently under construction, the immense building is already one of the tallest structures on Earth. Upon completion, it will be the fourth tallest building in the world.

That’s why “On the Roofs” — a secretive free-climbing duo — wanted to climb it while they could. With less security guarding the top at night, they made their way through the building and onto the roof. Eventually, they ran out of stairs and had to scale the building using less conventional methods. What they saw from the top is terrifying.

When the building opens in 2016, visitors will likely be able to climb to the top with the help of elevators, and they won’t have to risk their lives in the process. Although we’ll probably just wait a year to do this the safe way, we respect these daredevils and appreciate their insane footage.
