The Burj Khalifa opened in Dubai on Monday, taking the throne as the tallest building in the world. The Burj Khalifa stretches 2,717 feet (828 meters) into the sky. At more than 160 stories high, a perch at the top allows a viewer to see 60 miles into the distance.
Fireworks and parachute jumps marked the opening celebration. The Burj Khalifa cost $1.5 billion and took five years to build. The elevators move at speeds up to 40 miles per hour.
Taipei 101 in Taipei, Taiwan, previously held the record for tallest building. It is 1,671 feet high.
