Workers Install Spire Atop One World Trade Center in New York City

Today, workers installed the spire atop One World Trade Center, bringing the building to its full symbolic height of 1,776 feet. Provided the 408-foot addition is considered a spire rather than an antennae, this makes One World Trade Center the tallest building in the United States and the third-tallest in the world. The tower is currently scheduled to open for business in 2014.
