The Empire State Building

The Empire State Building is a 102-story skyscraper located in Midtown Manhattan, New York City, at the intersection of Fifth Avenue and West 34th Street. It has a roof height of 1,250 feet (381 meters), and with its antenna spire included, it stands a total of 1,454 ft (443.2 m) high. Its name is derived from the nickname 

for New York, the Empire State. It stood as the world's tallest building for 40 years, from its completion in 1931 until construction of the World Trade Center's North Tower was completed in 1972. Following the September 11 attacks in 2001, the Empire State Building was again the tallest building in New York.

The Empire State Building is currently the third-tallest completed skyscraper in the United States (after the Willis Tower and Trump International Hotel and Tower, both in Chicago), and the 22nd-tallest in the world (the tallest now is Burj Khalifa,located in Dubai).

The Empire State Building was designed by William F. Lamb from the architectural firm Shreve, Lamb and Harmon, which produced the building drawings in just two weeks, using its earlier designs for the Reynolds Building in Winston-Salem, North Carolina, and the Carew Tower in Cincinnati, Ohio.The construction was part of an intense competition in New York for the title of  "world's tallest building". Two other projects fighting for the title, 40 Wall Street and the Chrysler Building, were still under construction when work began on the Empire State Building. Each held the title for less than a year, as the Empire State Building surpassed them upon its completion, just 410 days after construction commenced. The project was completed ahead of schedule and under budget. Instead of taking 18 months as anticipated, the construction took just under fifteen.

The Empire State Building has one of the most popular outdoor observatories in the world, having been visited by over 110 million people. The 86th-floor observation deck offers impressive 360-degree views of the city. There is a second observation deck on the 102nd floor that is open to the public. It was closed in 1999, but reopened in November 2005.
