Mahoning Valley Historical Society, Youngstown

Though Wilford and Olive Arms haven't lived in their house for decades, the sprawling Arts and Crafts-style stone building still holds their story. Today, the original period rooms house the Arms Family Museum of Local History, where permanent and temporary exhibits interpret different facets of the estate's—and the surrounding area's— history. One explores the home's conception and construction with original photographs, sketches, and Lego models, while another unveils the history of radio-broadcasting in Mahoning Valley. The Valley Experience exhibit, meanwhile, showcases the Mahoning River region's cultural past, focusing on the daily lives of those who lived there, from the first Native Americans to European immigrants to African-American freemen.
