Baltimore was an innovator in the development of cast-iron architecture, but the city's heritage of buildings in this genre, once numbering over a hundred, has dwindled to only a handful today. The Baltimore region has also had a long tradition in iron production, beginning with the colonial era and continuing through the 1950s as Sparrows Point became the single largest steel complex in the world. Baltimore's Cast-Iron Buildings, back in print after an absence of several years, is a celebration of a unique aspect of Baltimore's architectural and industrial history. The authors examine cast-iron buildings in an integrated way to show how the material was fabricated and the buildings erected. They also explore the cast and wrought ironwork used for gates, fences, railings, and ornaments. The heavily illustrated work includes ironwork catalogs from the mid-1800s.
