The Chatham Historical Society offers a program to place date plaques on homes throughout the Borough of Chatham as a way of spreading word about Chatham's rich history, providing information about the houses of Chatham, and creating a sense of pride in our community. The Plaque Program is an easy and fun way to help make your home a part of Chatham's history. If you are interested in learning more about this program, you should contact the Plaque Program chair. A home owner who completes the requirements as outlined in the Adopt-A-House research packet will be given the option to purchase a recognition marker through the Historical Society, suitable for displaying on or in their home. The marker will indicate the date the home was built. Special recognition is available to homeowners whose houses are over 100 years old. Along with the completed research, homes over 100 years old will be evaluated by the Historical House Plaque committee according to criteria established by the Secretary of the Interior's Standards for Rehabilitation. If accepted, those homeowners will then be eligible to purchase a marker indication their house is 100 years old or older.

Initially presented at the Fishawack Festival on June 14, 2008, the program begins with photographs of buildings from the eastern end of Main Street and continues west to Lafayette Avenue. The photos are accompanied by text explaining some of the historically significant houses along the way. The presentation notes the number of demolished houses and considers what Main Street might have looked like today had they remained.

Walking Through Chatham’s Past at the Fair Mount Cemetery was presented in October 2003 and again in October 2010. Fair Mount Cemetery contains many fascinating clues to the history of the Chatham community and the lives of people who have lived in this town over the course of two centuries. Guests followed a guide through the cemetery encountering a few of the men and women - ministers, educators, farmers, doctors, shop keepers - whose lives and vision contributed to the unique development and character of the community. Chathamites, in costume, enacted the part of specific individuals near the site of their final resting places. Some of the participants were Ed Leithead as George Shepard Page and Jack Strangefeld as the Rev. Joseph Meeker Ogden.
