"The Burj Dubai ('Dubai Tower' in Arabic) is scheduled to open to the public on Monday. Its height, claimed to be 824.55m (2,705.2 feet), but believed to be 818m (2,684 feet) — either way, more than half a mile — makes it far taller than Taiwan's Taipei 101, which had been the world's tallest skyscraper at 509m (1,670 feet)."
