The world's tallest building Burj Khalifa has clinched its newest Guinness World Records title for being the highest man-made vantage point on earth.

For the first time, Emaar Properties, the developer of Burj Khalifa, on Tuesday opened the doors for the public to soak up unmatched views of the Dubai city from the all-new 'At the Top, Burj Khalifa SKY'.

The grand unveiling of Burj Khalifa-SKY was also attended by the adjudicators of the Guinness World Records, who declared Dubai's newest tourist attraction as the 'Highest Observation Deck' in the world.

At 555 metres high, Burj Khalifa bagged the laurel from CantonTower in Guangzhou, China, which held the record for its observation deck at 488 metres high.

The new honour adds to Burj Khalifa's three existing Guinness World Records titles for the Tallest Building, the Tallest Man-made Structure on Land and the Highest Restaurant from Ground Level.

Talal Omar, Country Manager for the Middle East and North Africa for Guinness World Record, said, "Burj Khalifa has done it again, surprising the world with its iconic scale and the ongoing creative enhancements. The new Guinness World Records title is another feather in the cap for Dubai."
