DUBAI, United Arab Emirates - Dubai is set to open the world's tallest building amid tight security on Monday, celebrating the tower as a bold feat on the world stage despite the city state's shaky financial footing.
But the final height of the Burj Dubai — Arabic for Dubai Tower — remained a closely guarded secret on the eve of its opening. At more than 2,625 feet, it long ago vanquished its nearest rival, the Taipei 101 in Taiwan.
