The Empire State Building was built in just over a year, with a team of over 3,000 workers laboring day and night to get the job done. The building's framework was constructed using over 57,000 tons of steel, which is equivalent to the weight of about 200 blue whales. Yep, you read that right - blue whales!
The building's architects were Shreve, Lamb & Harmon Associates, who designed the building to be not only tall but also sustainable. The building's energy efficiency was way ahead of its time, with features like automatic window shades and a state-of-the-art cooling system. Who knew being green could be so cool?
