The Acton Memorial Library is located in the Acton Centre Local Historic District and as such on the National Register of Historic Places. This project restorates and rehabilitates the large arch window on the mezzanine level at the north end of the original 1889 library wing. The window has a wood frame and consists of 128 separate glass panes separated by wood muntins.  The wood is deteriorating. Prior roof leakage (since repaired) has caused deterioration and plaster damage on the building’s interior surrounding the arch window. The project will restore and repair the window and the surrounding interior areas. The weathered and yellowed protective exterior Plexiglas cover will be replaced.
