Burj Khalifa

Surrounded by hotels, shopping destinations and entertainment options, the Burj Khalifa is the tallest building in the world. For sightseeing, the Burj has an outdoor observation deck, named At the Top on the 124th floor. The observation deck features the Behold Telescope, which allows visitors to view the surrounding landscape in real-time, and to view previously saved images such as those taken at different times of day or under different weather conditions.
