View of the upper floors of the Burj Khalifa, looking up from the observation deck on the 124th floor. The tallest building and tallest free-standing structure in the world, the Burj Khalifa offers impressive views of the surrounding landscape. The elevators at the Burj Khalifa are very quick, moving as fast as 10 m per second, but they are engineered so well that their movement is almost imperceptible.
