Ground Zero Area
Ground Zero Rescue workers also used the phrase "The Pile", referring to the pile of rubble that was left after the buildings collapsed. Even years later, the term "Ground zero" has become a shorthand for the site, even after construction on the new One World Trade Center and the National September 11 Memorial & Museum were well underway. In advance of the 10th anniversary of the attacks, New York City mayor Michael Bloomberg urged that the "Ground zero" moniker be retired, saying, "... the time has come to call those 16 acres what they are: The World Trade Center and the National September 11th Memorial and Museum."
