The mission statement of The Cornwall Historical Society is to preserve, educate and promote the history of Cornwall, Cornwall-on-Hudson and Mountainville. ​

Preserve - Educate - Promote

The Cornwall Historical Society was formed in 1999 by community members who joined together and attempted to save the historic Silliman School building which was located on the corner of Hazen and Main Street in the Town of Cornwall.  Unfortunately, the building was razed, but as a result of their effort, the Society was born.  The Silliman School building appears in the historical society's logo.
