what is the tallest building in the united states
List of tallest buildings in the United States As of 2018, One World Trade Center in New York City is considered to be the tallest skyscraper in the United States. Its spire brings the structure to a symbolic height of 1,776 feet (541 m), connoting the year The Declaration of Independence was signed, though the tip of the structure actually is measured at 1,792 ft (546 m).[3] However, using the more common criterion for the height of a building (the roof, not antenna) the observation deck elevation and highest occupied floor of One World Trade Center are surpassed by Chicago's Willis Tower (formerly and still commonly known as the Sears Tower)[4] and 432 Park Avenue.
