At the Top (Burj Khalifa)

At The Top, Burj Khalifa is a series of observation decks on the 124th and 125th floors of the Burj Khalifa which opened to the public on 5 January 2010. At 452 m (1,483 ft), it boasted the highest manmade observation deck in the world at the time This record was subsequently broken and regained twice with the respective openings of the At The Top, Burj Khalifa SKY and The Lounge, Burj Khalifa levels.

The 124th floor observation deck features augmented reality telescopes developed by Gsmprjct° of Montréal, 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, under different weather conditions, and a historical view taken by helicopter from before the tower's completion. To moderate the amount of crowding, entrance tickets are sold in limited quantities by specific dates and times. Once inside, there is no limit to the length of stay, but there is also no reentry privilege.

On 8 February 2010, the observation deck was closed to the public for two months after power-supply problems caused an elevator to become stuck between floors, trapping a group of tourists for 45 minutes.

When the tide is low and visibility is high, it may be possible to see the shores of Iran from the top of the skyscraper.
