One World Trade Center Stands 1,776 Feet High

With the observation deck and antenna¹, the 104-storey One World Trade Center (One WTC) stands 1,776 feet tall. This number represents the year the Declaration of Independence was signed (July 4, 1776). The skyscraper², previously³ known as The Freedom Tower, was built with several cutting-edge safety features, including a set of stairwells exclusively for emergency workers and a ventilation system with biochemical filters. One WTC is also one of the most environmentally-friendly office buildings in the world. Approximately 75% of the building materials were recycled from construction sites and up to 70% of its power comes from green energy. One WTC stands high above the two large reflecting pools where the Twin Towers previously stood.
