The official opening of the world's tallest tower saw two major surprises on Monday night.
The tower, previously known as 'Burj Dubai', was renamed 'Burj Khalifa' and its final height was revealed as 828 metres, a good 300 metres taller than the previous record holder.
The announcement was made in front of thousands of people who had squeezed into Dubai's downtown area to witness one of the world's biggest firework displays.
Dubai's ruler Sheikh Mohammed bin Rashid al-Maktoum renamed the tower after the president of the UAE and the ruler of neighbouring Abu Dhabi.
The final height of 828 metres was 10 metres higher than pundits had been predicting.
The opening coincided with the fourth anniversary of the accession of Sheikh Mohammed to power in the emirate of Dubai.
Emaar Properties revealed on Monday that the final cost of the tower would be $1.5 billion, with 90% of the building pre-sold.
