It’s absolutely impressive to see this building at 828 meters (160 stories) tall. It recently opened on Jan 6, 2010 with an equally impressive opening ceremony (see the videos at the bottom)

The building also managed to break a number of 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
