The world's tallest man-made structure is the 829.8 m (2,722 ft) tall Burj Khalifa in Dubai, United Arab Emirates. The building gained the official title of "Tallest Building in the World" at its opening on January 4, 2010.

The Council on Tall Buildings and Urban Habitat, an organization that certifies buildings as the "World’s Tallest", recognizes a building only if at least fifty percent of its height is made up of floor plates containing habitable floor area.^[1] Structures that do not meet this criterion, such as the CN Tower, are defined as "towers".

There are dozens of radio and television broadcasting towers which measure over 600 metres (about 2,000 ft) in height, and only the tallest are recorded in publicly available information sources.

We invite you to begin your Dubai sightseeing with Burj Khalifa, the tallest building in the world. The Burj Khalifa skyscraper is a world-class destination and the magnificent centerpiece of Downtown Dubai, Dubai's new urban masterpiece. The world's tallest building is surrounded by hotels, must-visit shopping destinations and a world of entertainment options.
