One World Trade Center has an architectural height of 1,776 feet.
The height was deliberately chosen to symbolize 1776, the year the United States Declaration of Independence was adopted. The tower stands at the World Trade Center site in Lower Manhattan, where it replaced the original twin towers destroyed in the September 11, 2001 attacks.
The building reaches 541.3 metres, and its roof is much lower than its official architectural height because the number includes the large spire. One World Trade Center topped out in 2013 and opened in 2014. It has 104 floors above ground, although its floor numbering also reflects mechanical and other specialized levels.
A common mix-up is to confuse the tower’s architectural height with its roof height. The roof is about 1,368 feet high, while the spire brings the recognized architectural measurement to the symbolic 1,776-foot figure.
