Empire State Building
The
Empire State Building is a 102-story Art Deco skyscraper in New
York, NY. Its name is derived from the nickname for the state of New
York. It stood as the world's tallest building for more than forty
years, from its completion in 1931 until the construction of the World
Trade Center North Tower in 1972, and is now once again the tallest
building in New York after the destruction of the World Trade Center
in the September 11, 2001 attacks.
The Empire State Building has been named by the American Society of Civil Engineers as one of the Seven Wonders of the Modern World. The building and its street floor interior are designated landmarks of the New York City Landmarks Preservation Commission, and confirmed by the New York City Board of Estimate. On June 24, 1986 it was designated as a National Historic Landmark by the U.S. Department of the Interior.
