Many of the places that helped make Dayton a center of innovation were lost to history, while others survived and adapted, representing the city's spirit of revitalization. Some of the city's distinctive and significant structures, such as Steele High School and the Callahan Building, were demolished, while others, including the Arcade and Centre City Building saw hard times but now await redevelopment. Entire neighborhoods, such as the Haymarket, and commercial districts, such as West Fifth Street, vanished and show no traces of their past. Join author Andrew J. Walsh as he discusses his book Lost Dayton Ohio, c. 2018, and explores the diverse selection of retail, industrial, entertainment, and residential sites from Dayton's disappearing legacy.
