The Society maintains a museum and Glendower State Memorial. The Museum is housed in Harmon Hall, a three story, 28,000-square-foot brick building. It contains artifacts from prehistoric eras to the mid-20th century. Glendower is a restored Greek Revival mansion, one of the five built during the 19th century. John Milton Williams, a framer of the state's constitution, employed Amos Bennett to build the rectangular central unit in the 1840s. The 13 rooms include a formal drawing room with two fireplaces. All rooms, furnished with Empire and early Victorian style pieces, reflect the skilled local craftsmen and gracious living of the residents.
