One World Trade Center

One World Trade Center, constructed on the site of the original World Trade Center complex, topped out in 2013 and reaches a symbolic architectural height of 1,776 feet, making it the tallest building in the United States. The tower is the centerpiece of the rebuilt World Trade Center complex and was developed as part of the post-9/11 site redevelopment and memorialization efforts. It contains office space, an observation facility, and is adjacent to the National September 11 Memorial & Museum.
