Over the past few years, One World Trade Center (WTC) has risen to tower over other buildings in lower Manhattan, in New York City. Construction workers are adding steel columns to the building’s 100th floor, bringing the building’s current height to 1,271 feet. That’s higher than the city’s current tallest building, the Empire State Building. It rises 1,250 feet to the top observation deck. If you count the Empire State Building’s rooftop antenna, the skyscraper still stands taller at 1,454 feet than One WTC.
Once completed, One WTC will be an achievement filled with symbolism for New York City. The building will replace the twin WTC towers, which collapsed ten years ago following the worse attack on U.S. soil in the nation’s history. On Sept. 11, 2001, thousands of Americans lost their lives when terrorists hijacked four airplanes. Two of the planes toppled the twin towers. One jet destroyed a section of the Pentagon, near Washington, D.C. Another crashed into a field in Pennsylvania.
At the time, the twin towers were the tallest buildings in New York. Now, waterfalls pour into two reflecting pools where the towers stood, as a memorial to the victims. The memorial opened in September on the 10th anniversary of the attacks. Near the memorial, construction on new office and retail spaces is moving along.
A Height Debate
Construction on One WTC, which began in April 2006, is estimated to be completed by 2014. When completed, the office building will have 104 floors and will stand 1,368-feet tall at roof level — that is the same height as the north tower of the original World Trade Center. A spire will rise from the roof, bringing the new building’s height to 1,776 feet. The number represents the year our nation was founded.
At full height, One WTC will be considered the tallest building in the U.S., and the third tallest in the world. The tallest skyscraper is the Burj Khalifa, in Dubai, United Arab Emirates, which stands at 2,717 feet. However, there is some debate among record-keepers over whether to count the height of needles, antennas, spires and other rooftop objects when declaring the tallest buildings. Not counting needles, the Willis Tower (formerly the Sears Tower), in Chicago, will remain the country’s tallest tower at 1,450 feet.
