The Cohasset Historical Society was founded in 1928 to collect, preserve, exhibit, and educate the public about the history of Cohasset and the region. 

The Society currently has over 30,000 accessioned items, including 4,000 historic textiles and clothing dating from the 1700s to the present day, and over 7,000 photographs from daguerreotypes to digital images and numerous memorabilia showcasing the town’s theatrical past. The Society cares for nineteenth-century furniture, decorative arts, and an extensive collection of paintings depicting the town’s landscapes, seascapes, people, and places. Also preserved are essential documents such as military service records, letters, and diaries.​

In addition, the Society owns and cares for four historic buildings, three of which are listed on the National Register of Historic Places. Each property is a unique museum depicting a different aspect of Cohasset’s past and hosts both temporary and permanent exhibitions.

Today, the Society offers opportunities for every interest, including research opportunities and events such as educational lectures, cocktail parties, clambakes, and house tours. The Society is rooted in the Cohasset community and relies on the community for support. Memberships with the Society allow us to continue our mission, and we welcome volunteers and your active participation.

​As we move beyond Cohasset’s 250th anniversary, celebrated in 2020, the Society and its pursuit of collecting, preserving, exhibiting, and preserving our town’s history is more important than ever.
