The Vassalboro Historical Society Museum is maintained year-round in the former East Vassalboro Grammar School located on State Route 32, just north of the Town boat ramp on China Lake.

The Society’s Library houses items including old account books and ledgers, day books and diaries, family Bibles, scrapbooks, etc. A large collection of Vassalboro photographs is arranged in albums and kept on display for visitors to peruse.

The Museum houses an extensive collection related to Vassalboro’s Oak Grove Seminary and Oak Grove-Coburn School; it includes yearbooks and catalogs, as well as other memorabilia.

In the two large rooms on the main floor, changing displays illustrate aspects of Town life at various times in the past.

In 2010, a life-long resident of East Vassalboro bequeathed her home and all of its contents to the Historical Society; several displays feature part of this collection.
