Taipei
Taipei 101 is a 101-floor landmark skyscraper that claimed the title of world's tallest building when it opened in 2004, a title it held for six years before relinquishing it to the Burj Khalifa in Dubai. Designed by C.Y. Lee & Partners and constructed by KTRT Joint Venture, Taipei 101 measures from ground to top, making it the first skyscraper in the world to break the half-kilometer mark in height. Built to withstand typhoon winds and earthquake tremors, its design incorporates many engineering innovations and has won numerous international awards. Taipei 101 remains one of the tallest skyscrapers in the world and holds LEED's certification as the world's largest "green" building. Its shopping mall and its indoor and outdoor observatories draw visitors from all over the world. Taipei 101's New Year's Eve fireworks display is a regular feature of international broadcasts.
