Dubai opened the world’s tallest skyscraper on Monday, and named the gleaming glass-and-metal tower Burj Khalifa. A multimedia presentation witnessed by Dubai’s ruler and thousands of onlookers at the base of the tower said the building was 828 metres, or 2717 feet, tall.
The Burj vanquished its nearest rival, the Taipei 101 in Taiwan. The building has the most stories and highest occupied floor of any building in the world, and ranks as the world’s tallest structure, beating out a television mast in North Dakota. It is more than twice the height of New York’s Empire State Building.
The newly-opened tapering metal-and-glass spire cost about $1.5 billion. The Burj is billed as a “vertical city” of luxury apartments and offices. It has four swimming pools, a private library and a hotel designed by Giorgio Armani.
