The Burj Khalifa is an absolutely impressive building. To put it’s 829m height in perspective, you could basically stack two Willis (Sears) Towers on top of each other and they would be the same height. The next tallest building in the world is a full 225m shorter than the Burj Khalifa. The Burj Khalifa truly stands in a category of it’s own.
We spent a couple of hours on the 124th floor observation deck enjoying the sunset and taking lots of pictures at night. Here is one of the pictures that I took looking up the highway at some of the neighboring skyscrapers.
