The Arms Family Museum is housed in Greystone, a century-old Arts and Crafts-style residence. On the first floor, in original period rooms, visitors can experience the Arms's love of handicraft, medieval architecture and design, and the natural environment. The lower level and second floor feature exhibits that explore the history of all the people who have lived in the Mahoning Valley. Artifacts displayed and interpreted in changing galleries help the visitor understand the way of life in the Mahoning Valley for different people at different times, whether Native American, pioneer settler, Welsh coal miner, African American freeman, or Eastern European immigrant.
The museum offers exhibits, guided tours for student groups, teacher resource kits for loan, curriculum guides, teacher in-services, in-class traveling suitcase outreach presentations, and research library access.
