When it comes to the highest observation decks in the world, Burj Khalifa does not occupy pole position.
The world's tallest building's observation deck "At the Top" gives the view of the Arabian desert from just 452 meters but does not actually lead in the field of observation decks.
In fact, the 828-meter tall skyscraper in Dubai only makes third place in a list of the world's highest observation decks just compiled by Emporis (www.emporis.com), the international provider of building data.
Topping the ranking is Canton Tower, at 618 meters the world's third-tallest structure, which is home, at 488 meters, to the world's highest publicly-accessible observation deck.
The tower not only provides a magnificent view of Guangzhou, but also offers a further attraction to visitors with a particularly good head for heights - the chance to circle the top of tower in glass pods 460 meters above the ground.
The Shanghai World Financial Center ranks at similarly dizzying heights.
Its Skywalk 100, a 55-meter long glass bridge 474 meters up the tower, puts it in second place in the ranking.
It will have to give up its current spot, though, when its neighbor Shanghai Tower is completed next year.
At the spectacular height of 557 meters, Shanghai Tower's observation deck will then far outstrip even the current record-holder.
Also not for the faint-hearted is Willis Tower, the tallest skyscraper in the United States.
Originally opened as far back as 1974, more recently installed glass balconies with transparent floors on the west side of the building invite visitors to take an unobstructed look down.
Here one can experience the unique feeling of hovering 413 meters above the city. (ANI)
