Taipei 101 is a landmark skyscraper located in Taipei, Taiwan. The 1670 foot (509 meter) building ranked officially as the world's tallest from 2004 to 2010 until the opening of the Burj Khalifa in Dubai. Designed by C.Y. Lee & Partners, the building's architecture was inspired by traditional Chinese designs, with a shape resembling a pagoda. The sectioned tower is also inspired by the bamboo plant, which is a model of strength, resilience, and elegance. The tower's design specifications are based on the number "8", a lucky number in traditional Chinese culture; it features 8 upward-flaring sections, and is supported by 8 super columns.

Construction for Taipei 101 was started in 1999 and completed in 2004. In July 2011, the building was awarded LEED Platinum certification, the highest award in the Leadership in Energy and Environmental Design (LEED) rating system and became the tallest and largest green building in the world.

Taipei 101 is mainly an office building with the large Taipei 101 Mall at its base. Taipei 101 features an Indoor Observation deck (89th floor) and an Outdoor Observation deck (91st floor). Both offer 360-degree views and attract visitors from around the world.
