“Within These Walls,” a living history play reprised annually at 16 Elm St., Ipswich, was performed at the Smithsonian National Museum of American History in Washington, D.C., on Aug. 3 by members of Ipswich-based The Actors Company. The home that formerly stood at 16 Elm St. was accepted by the Smithsonian in 1963, after it was scheduled to be demolished. It was saved by local residents Kay Thompson and Helen Lunt, and is on permanent display at the museum. J.T. Turner’s play illustrates the arc of American history by following the lives of five families who lived in the Ipswich house over 200 years. The annual free local performance will take place on Sept. 28.
