Burj Khalifa
Dubai
The Burj Khalifa is a megatall skyscraper located in Dubai, United Arab Emirates. Designed by Skidmore, Owings Merrill, it is the world's tallest structure, with a total height of 829.8 m (2,722 ft, or just over half a mile) and a roof height (excluding the antenna, but including a 242.6 m spire) of 828 m (2,717 ft). It also has held the record of the tallest building in the world since its topping out in 2009, surpassing the Taipei 101, which had held the record since 2004.
Construction of the Burj Khalifa began in 2004, with the exterior completed five years later in 2009. The primary structure is reinforced concrete and some of the structural steel for the building originated from the Palace of the Republic in East Berlin, the seat of the former East German parliament. The building was opened in 2010 as part of a new development called Downtown Dubai. It was designed to be the centerpiece of large-scale, mixed-use development.
