Who We Are

Three museums in one…

Deep River Historical Society
1. Our Buildings

The Stone House was built in 1841 from locally-quarried stone. Three generations of the Southworth family called the Stone House their home, where we now display some of their original furnishings as well as donations resonant of that period. The property, which was bequeathed to us from Ada Southworth Munson in 1946, also includes a Carriage House (available for event rentals), a Bleach House from the days of ivory manufacturing, and extensive grounds.

2. Our Collections

In addition to the Southworth bequest of a furnished home, the Deep River Historical Society curates our community’s history through artifacts, documents, maps, diaries, letters, art, and much more. Our rotating exhibits have recently highlighted Deep River’s centuries of industry from wharf to waterfall, contributions to women’s suffrage and activism, and the sacrifices of the men and women of Deep River during World War II. And we are planning more!

3. Our Programs

We provide Deep River with a lively roster of events, including period teas, the strawberry social, antique car shows, and the holiday Festival of Trees, along with year-round, though-provoking talks by authors and residents about local history and its colorful personalities.
