The tallest building in the United States is One World Trade Center, located in New York City. Also known as the Freedom Tower, it was completed in 2014 and stands at 1,776 feet, including its spire, symbolizing the year of American independence. One World Trade Center was built to replace the original World Trade Center towers that were destroyed during the September 11 attacks. The building incorporates advanced safety features and sustainable design elements. Its observatory offers breathtaking views of the city and serves as a poignant reminder of resilience, hope, and the enduring spirit of New York.
