York City Hall, was designed by Cass Gilbert. At 792 feet (241 m), it became the world's tallest building upon its completion in 1913, an honor it retained until 1930. 40 Wall Street, a 71-story, neo-Gothic tower designed by H. Craig Severance, was the world's tallest building for a month in May 1930. The Chrysler Building in New York City took the lead in late May 1930 as the tallest building in the world, reaching 1,046 feet (319 m). Designed by William Van Alen, an Art Deco style masterpiece with an exterior crafted of brick, the Chrysler Building continues to be a favorite of New Yorkers to this day. The Empire State Building, nine streets south of the Chrysler in Manhattan, topped out at 1,250 feet (381 m) and 102 stories in 1931. The first building to have more than 100 floors, it was designed by Shreve, Lamb and Harmon in the contemporary Art Deco style and takes its name from the nickname of New York State. The antenna mast added in 1951 brought pinnacle height to 1,472 feet (449 m), lowered in 1984 to 1,454 feet (443 m). The World Trade Center officially surpassed the Empire State Building in 1970, was completed in 1973, and consisted of two tall towers and several smaller buildings. For a short time the World Trade Center's North Tower―completed in 1972―was the world's tallest building, until surpassed by Sears Tower in 1973. Upon completion, the towers stood for 28 years, until the September 11 attacks destroyed the buildings in 2001. The Willis Tower (formerly Sears Tower) was completed in 1974. It was the first building to employ the "bundled tube" structural system, designed by Fazlur Khan. It was surpassed in height by the Petronas Towers in 1998, but remained the tallest in some categories until Burj Khalifa surpassed it in all categories in 2010. It is currently the second tallest building in the United States, after One World Trade Center, which was built to replace the destroyed Trade Towers. Momentum in setting records passed from the United States to other nations with the opening of the Petronas Twin Towers in Kuala Lumpur, Malaysia, in 1998. The record for the world's tallest building has remained in Asia since the opening of Taipei 101 in Taipei, Taiwan, in 2004. A number of architectural records, including those of the world's tallest building and tallest free-standing structure, moved
