Cement City
Donora, PA · est. 1997
Built in 1916–17 to house workers at American Steel & Wire's Donora plant, Cement City was a planned community of 100 units in 80 Prairie-style buildings. Its buildings were poured in place from concrete — an experimental construction method meant to deliver durable, affordable company housing quickly. One of several such concrete communities across the country in that era, it endured to shelter generations of steelworkers' families and is now a National Register Historic District.
