Taipei 101 is the skyscraper famous for fireworks launched from its exterior during Taipei's New Year's Eve celebration.
The fireworks display uses the building's façade as a vertical launch and visual surface, creating bursts that appear to travel around the tower. The event is staged in Taipei, Taiwan, and has become one of the most widely recognized New Year's spectacles in East Asia.
Taipei 101 opened to the public in 2004 and was designed by C.Y. Lee & Partners. Its name refers to the 101 floors above ground. The tower was the world's tallest building from its completion until the opening of Dubai's Burj Khalifa in 2010.
The fireworks are not the building's only engineering feature. Taipei 101 contains a large tuned mass damper, a suspended steel sphere designed to reduce movement caused by wind and earthquakes. That stabilizing device is sometimes mistaken for a fireworks mechanism, but the two features serve entirely different purposes.
