5 Things You Didn't Know About One World Trade Center

One World Trade Center officially opened in Manhattan on November 3, 2014. The new tower, along with the rest of the World Trade Center complex, replaced the Twin Towers and surrounding complex, which were destroyed by terrorist attacks on 9/11. Here are 5 things you didn’t know about this amazing building.


It’s Known By More Than One Name What locals and tourists alike call the Freedom Tower is officially One World Trade Center. But the building has a long list of nicknames, including the 9/11 Observatory, the WTC Observatory, and the 9/11 Tower. Don’t worry -- if you use any of these terms, people will be able to give you directions. But since 2009, its proper, legal name has been One World Trade Center. Poignantly, that is the same official name that the North Tower of the original World Trade Center complex carried.

The Height of the Building Is Significant One World Trade Center has the distinction of being the tallest building in the United States, the tallest building in the Western Hemisphere, and the sixth-tallest building in the world. The construction of One World Trade Center was carefully planned to be 1,776 feet tall. This number corresponds with the year of the signing of the Declaration of Independence. Although the height of the building is 1,368 feet, which is the same height as the original Twin Towers, an added spire increases the height by another 408 feet.


The Lobby is Adorned in Marble From The Old Twin Towers There are several instances where the new One World Trade building draws inspiration from the former Twin Towers. The lobby uses white marble taken from the lobby of the former World Trade Center. The central spire is visually reminiscent of the original building. The building’s 200-foot footprint is nearly identical to the footprints of the original Twin Towers.

Visitors Seldom Have to Wait for an Elevator With 71 elevators, those working at One World Trade Center have plenty of choices on how to get to their office. Five of the elevators are express, which take people all the way to the top at 22.5 mph in about one minute. The express elevators are powered by eight electric motors located on the building’s roof and use a pulley and cable system.

It Was Designed With Safety in Mind Given the understandable concern about rebuilding the towers, extra security features were added to ensure the safety of One World Trade and its tenants. The construction includes a reinforced concrete base, pressurized stairwells, blast-resistant windows, biological and chemical filters through its ventilation system, and more. Security measures such as vehicle screening, surveillance cameras, and video-analytic computer software can detect potential threats.
