The Old Courthouse Museum Society was formed in 1977 to help establish an Orange County historical museum and archives in the Old Orange County Courthouse. Its purpose is to gather and preserve materials relating to the history of Orange County. In cooperation with the Orange County Historical Commission, the Society supports Old Courthouse activities with a docent program, souvenir sales, exhibits, and publicity, as well as arranging meetings and other events. The Society's overall goal is to foster an appreciation of local Orange County history with a strong emphasis upon education so that young citizens of the County may gain an appreciation and knowledge of those who passed this way before.
Members serve as volunteer docents, or assist with programs, publicity, or collection development.
If unable to serve in an active capacity, the contribution of membership dues helps to support Society activities. The Society holds at least three regular meetings open to the entire membership each year with a selected speaker at each meeting. In addition, members receive notification of activities and special exhibits in the Exhibit Gallery.
