20 Incredible Photos of the Construction of the Empire State Building

The Empire State Building, the 102-story skyscraper on Fifth Ave. between West 33rd and 34th Streets in Midtown Manhattan stands 1,454 feet tall. It was the world’s tallest building for 39 years from its completion in 1931 until the World Trade Center’s North Tower was completed in 1970. It has been named one of the Seven Wonders of the Modern World by the American Society of Civil Engineers.

Excavation of the site began on January 22, 1930, and construction of the building began on March 17. The project involved 3,400 workers, mostly European immigrants, as well as hundreds of Mohawk iron workers. Despite an astonishing lack of safety regulations, only five workers died during construction.

The construction of the Empire State Building was part of a competition in New York City for the “world’s tallest building” with 40 Wall Street and the Chrysler Building. The Empire State Building surpassed both buildings in height upon its completion on April 11, 1931, 12 days ahead of schedule.
