The Iron Work Farm continues its series of “4^th Sunday” open houses at Jones Tavern (128 Main St., 1 to 3 p.m.) and the Jones-Faulkner Homestead (5 High St., 3 to 5 p.m.)

In this important anniversary year, come visit the homes of two families closely involved with the American Revolution.  Jones Tavern, Acton’s oldest standing tavern, is open from 1 to 3 p.m.  At the Faulkner Homestead from 3 to 5, meet members of the Nashoba Valley Weavers’ Guild, and also learn about the discoveries  from the recent driveway excavations.  During the open house archaeologist Kimberley Connors will lead volunteers in a further examination of the large dirt pile.  To take part in the dig, sign up at https://forms.gle/GvmDAWE9afDvoXD7A, or email Kimberley at dig@archeducation.org.

No charge;  parking on site or on nearby MBTA lots. Check www.ironworkfarm.org for more details.
