Gilbert Town Hall is home to a 9/11 Memorial[1] that features an eight-foot steel girder beam[2] that held up the North Tower of the World Trade Center.[citation needed] Former Gilbert Fire Chief Collin DeWitt raised money for three years to create the memorial and bring the beam from New York City to Arizona.
