At 509 meters high, this was the world's tallest building from 2004 to 2010, when the Burj Khalifa in Dubai surpassed it. The tower is reminiscent of a pagoda or a stalk of bamboo and designed to withstand typhoons and earthquakes common in Taiwan. Floors one through five are a shopping center and both the indoor (89th floor) and outdoor (91st floor) observation decks offer a 360-degree panoramic view.
