The #BurjKhalifa is 830m high. However, the last 244m are uninhabitable and only built on top to reach the height. So it is actually "only" 586m high. They call this approach #VanityHeight. It's a bit vain but it's clever from a business point of view.

Incidentally, the steel for the foundations of Burj Khalifa came from the demolition of the „Palast der Republik“ in Berlin 😀

The whole story of the building, even about its name is interesting 🧐
And finally … it’s beautiful 😀
Even the observation deck is not the highest in the world 😉.
„The highest observation deck is located at 561.3m (on the 632m Shanghai Tower).“
