One World Trade Center became the tallest structure in New York City on April 30, 2012, when it surpassed the height of the Empire State Building The tower’s steel structure was topped out on August 30, 2012. On May 10, 2013, the final component of the skyscraper’s spire was installed, making the building, including its spire, reach a total height of 1,776 feet (541 m). Its height in feet is a deliberate reference to the year when the United States Declaration of Independence was signed. The building opened on November 3, 2014. The new World Trade Center complex will initially include three other high-rise office buildings, which will be built along Greenwich Street, and the National September 11 Memorial & Museum, located just south of One World Trade Center, where the original Twin Towers stood. The construction of the new building is part of an effort to memorialize and rebuild following the destruction of the original World Trade Center complex.
