Is freedom tower the biggest tower?

One World Trade Center, commonly known as the Freedom Tower, is the tallest building in the United States and the Western Hemisphere, standing at 1,776 feet, including its spire. However, it is not the tallest building in the world; that title is held by the Burj Khalifa in Dubai, which reaches a height of 2,717 feet. While Freedom Tower is significant in terms of its height and symbolic importance, it is not the biggest tower globally.
