In the same year the Home Insurance Building was destroyed, one of the oldest and most famous skyscrapers, the Empire State Building, opened in New York City. Later in the 20th century, people started building skyscrapers in cities that did not have many tall buildings in the past.

It took the record from the World Trade Center in New York City, which opened in 1970 but was destroyed in the September 11, 2001 attacks.
