Taipei 101, Taipei, Taiwan – 1671 ft (509 m) 101 Floors

Taipei 101 became the world’s tallest building to be constructed in the new millennium and the first to cross the half-kilometer mark. The construction cost was $1.76 billion and it was completed in 2004. This multi-use steel-and-glass skyscraper was designed by C.Y. Lee & Partners and has 61 elevators. It reflects the traditional Chinese pagoda, with a soaring podium base, eight tiers of eight stories (eight is considered a number representing prosperous growth in China), narrow pinnacle tower, and a spire.
The building has an 18 ft, 882-ton ball-shaped damper at the top that counteracts swaying motions during typhoons and earthquakes. Although CTBUH only takes into consideration the floors above ground level, there are 5 floors underground too. The number “101” represents not only the number of floors, but also the mailing code of Taipei’s international business district. It was hailed as one of the Seven New Wonders of the World by Newsweek magazine in 2006 and as one of the Seven Wonders of Engineering by The Discovery Channel in 2005.
