The Burj Khalifa tower in Dubai is already the tallest building in the world. Now, it also boasts the record for having the highest observation deck of any building. At The Top Sky opened to the public in October and is situated up on the 148th floor of the building, 555 m (1,821 ft) above the ground.

Adjudicators from Guinness World Records were on hand at the opening of the attraction to confirm the record. Gerald Donovan's 360-degree panorama image of the view from the top of the Burj Khalifa gives some idea of the view that visitors to the attraction can expect.

Those who do visit the attraction will first be taken to the 124th floor where the tower's At The Top observation deck is situated. Designed as a tribute to Arab arts and culture, visitors are able to take in 360 degree views and use viewfinders to pick out places across the skyline.

A second elevator takes visitors the rest of the way to the new At The Top Sky. The journey to the observation decks includes a multimedia presentation about Dubai's history and the Burj Khalifa.

In addition to spectacular views, the At The Top Sky attraction has a five-star premium lounge and an interactive screen that allows visitors to discover destinations in the city. There is also an outdoor terrace that's said to be the highest man-made vantage point on Earth.

Among the other records held by the Burj Khalifa are tallest man-made structure on land (so far) and highest restaurant from ground level.
