Where is the tallest building in the world located?
Burj Khalifa is a mega tall skyscraper in Dubai, United Arab Emirates. Actually, it is the tallest building in the world (2,722 ft)!
The skyscraper was designed as the centerpiece of a large-scale development including more than 30,000 homes, 9 hotels, a parkland and 19 residential towers.
The tower was erected in 2010.
Can you imagine a man who can climb such a high building with no special equipment? It's Alain Robèrt, a French Spiderman! He did it in 2011.
