The Harrison Township Historical Society headquarters is in Old Town Hall, which is listed in the NJ State and National Registers of Historic Places. Old Town Hall has free museum exhibits on weekends during the spring and fall, and is also home to the Raccoon Valley General Store.
The Historical Society, which welcomes new members, is supported by grants and donations, as well as fundraising events like the Ground Hog Dinner, Spring Afternoon Tea, and Fall Ghost Walk.
