The Burj Khalifa, the tallest man-made structure on earth, was opened on January 4, 2010.
330,000 cubic metres of concrete were used in the construction, equivalent to the weight of 100,000 elephants as per Burj Khalifa Facts.
The aluminium required is equivalent to the weight of five Airbus A380 planes.
At 828 metres (2716.5 feet), the Burj Khalifa is about twice the height of the Empire State Building and three times the height of the Eiffel Tower.
It has 163 floors plus 2 below ground. Construction began on January 12, 2004 and finished on October 1, 2009.
The Burj Khalifa has the world's lengthiest lift, which is 140 stories long and travels at a speed of 10 metres per second.
The Burj Khalifa's lift is the fastest elevator in the world and has a maximum speed of 36 km/hour (600 metres/minute).
The Burj Khalifa's façade is made up of 26,000 hand cut glass panels, engineered to conserve energy and reduce heat transfer.
Its design was inspired by the shape of a Spider Lily or hymenocallis, a desert flower.
On level 122 of the Burj Khalifa is Atmosphere, the world's highest restaurant/lounge bar, spanning 1,030 square metres with views of Dubai and the Arabian Gulf.
At Burj Khalifa SKY on Level 148, at a height of 555 metres (1,821 ft), visitors can enjoy views of Dubai and beyond.
