The Acton 9/11 Memorial was dedicated to Acton residents Amy Sweeney and Philip Rosenzweig who were both on American Airlines Flight 11 and recognizes public safety personnel. With the help of the Sweeney and Rosenzweig families along with the 9/11 Committee and Stamski and McNary, Inc., a design was developed to bring a piece of history, reflection and dignity home to Acton. The memorial features steel from the world trade center that was dispensed by the Port Authority of New York and New Jersey. It was dedicated on September 11, 2011, the ten -year anniversary of the fateful day.
