The second tallest building in the world is more like a vertical city than a building. Think of it like this: the 632-meter tall Shanghai Tower is a bustling mixed-use metropolis with more green space (and even more people) than many cities on the ground can boast of having.

The statistics on the building, which ranks only behind Dubai’s Burj Khalifa in height, are staggering: 521,000 meters squared of floor space, 106 elevators, a weight of 1,200 metric tons, the ability to hold 30,000 people (it really is like a small city), and the kicker—one-third of the building is dedicated entirely to green space.
