The Chelmsford Historical Society, Inc., organized in 1930, is a non-profit organization of people who care about Chelmsford's heritage and local history. The society is an educational and cultural resource for the Town of Chelmsford and the Merrimack Valley, dedicated to the preservation of the historical heritage of our town for the good of all of the people of Chelmsford.

Our mission is to collect, preserve, exhibit and interpret documents and artifacts reflecting the life of Chelmsford and its people from the 17th century to the present.  At the Barrett-Byam Homestead-home of the Chelmsford Historical Society-visitors of all ages learn about Chelmsford's rich history and culture by touring period rooms and exhibits, delving into family or local history, and participating in educational programs and social activities.

Both the society and the museum are of particular interest to anyone wanting to learn how more than 350 years of Chelmsford's history have produced this fine town in which to live.

The Barrett-Byam Homestead is located 1¼ miles from Chelmsford Center on Route 27, Acton Rd. One mile from the center, look for the Barrett-Byam Homestead sign on your right at Byam Road. Go right on Byam Road ¼ of a mile to the homestead on your left.

We are open by appointment and during special events. See our Calendar for a list of scheduled events.
