Striking lightning: Bolt hits the world's tallest building in a spectacular display in the skies above Dubai

The bolt hit the emirate's Burj Khalifa, which stands at a massive 828-metres high.

It is just as well the tower's spire, which was constructed with 4,000 tonnes of steel, was built so lightning is deflected away from the main structure.


World Records

At over 828 metres (2,716.5 feet) and more than 160 stories, Burj Khalifa holds the following records:

• Tallest building in the world

• Tallest free-standing structure in the world

• Highest number of stories in the world

• Highest occupied floor in the world

• Highest outdoor observation deck in the world

• Elevator with the longest travel distance in the world

• Tallest service elevator in the world
Tallest of the Supertall

Not only is Burj Khalifa the world’s tallest building, it has also broken two other impressive records: tallest structure, previously held by the KVLY-TV mast in Blanchard, North Dakota, and tallest free-standing structure, previously held by Toronto’s CN Tower. The Chicago-based Council on Tall Buildings and Urban Habitat (CTBUH) has established 3 criteria to determine what makes a tall building tall. Burj Khalifa wins by far in all three categories.
Height to architectural top

Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building. This includes spires, but does not include antennae, signage, flagpoles or other functional-technical equipment. This measurement is the most widely used and is used to define the Council on Tall Buildings and Urban Habitat rankings of the Tallest Buildings in the World.

Highest occupied floor
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest continually occupied floor within the building. Maintenance areas are not included.

Height to tip
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element. This includes antennae, flagpoles, signage and other functional-technical equipment.
