The Grand Blanc Heritage Association is located at 203 E. Grand Blanc Road in the City Hall complex. Founded in 1972, it is incorporated by the State of Michigan as a not-for-profit, educational, public service organization. The function of the Association is to discover, document, collect, preserve, research and exhibit any tangible materials that help to establish or illustrate the history of the community and surrounding area.
In 1833, eleven people established the First Congregational Church of Grand Blanc. The congregation, which held its earlier services in homes, and later schoolhouses, built their first house of worship in 1855. They replaced it with the current building in 1885. The building served its congregationalists for eighty-three years; its last worship service was October 6, 1968. Purchased by the City of Grand Blanc in 1967, it became the home of the City municipal offices.
In 1976 the City of Grand Blanc gave the Association a single room to display items collected from its members. The Heritage Museum has since grown to two floors filled with exhibits. These items have been donated to the Association for the education and enjoyment of the community. The Museum is administered by the Grand Blanc Heritage Association Board of Directors and its volunteers.
