Mission Statement:
The Braintree Historical Society promotes an interest in local history through association, mutual encouragement, and study.  Through historical research and education, it provides a means for members to become aware of the value of their American heritage and their community's part in its development. It further engages in creating and maintaining collections, preserving historical documents, relics and sites, and advancing knowledge of Braintree's famous son, Sylvanus Thayer.
