The Shard weighs as much as 25,000 double-decker buses. Imagine all those buses stacked neatly—that’s a lot of traffic jams. It also has 11 high-speed elevators that go at 6 meters per second. That’s faster than your last Uber ride.
Oh, and it was completed in 2012, just in time for the Olympics. The builders must have been sweating, thinking, “Please don’t let it collapse during the opening ceremony.” Spoiler: it didn’t.
