The world's tallest tower, developed by Emaar Properties,
was unveiled Monday night to a crowd of thousands and the
world in a crescendo of fireworks, lasers and fountain displays.

The official height of the tower, unveiled as 'Burj Khalifa', was
announced as 828 metres (2,716.5 ft). A closely guarded secret,
the official height of Burj Khalifa was flashed onto a giant screen
before an estimated crowd of more than 400,000, as lasers and
fireworks lit up the night sky.

Fireworks cascaded from the tower's spire to the base and lasers
blazed out from all levels leaving the crowds awestruck. The height
was disclosed in arithmetic progression, with the numbers being
flashed onto the screen, one after another. The tower's height
breaks all existing world records for tall buildings.
