More than a century after they last belched smoke and discharged molten iron, the surviving stacks of stone blast furnaces bear silent testimony to the birth of heavy industry in western Pennsylvania. The massive, pyramid-like form and intricate, unmortared stonework of these archaic towers call to mind the ruins of a not-so-long-vanished civilization. As iron-producing artifacts, the furnace stacks are, in fact, part of a lineage that dates back more than 3,500 years. Examine the structure's role in local history, however, and you will discover strong connections to the present. Western Pennsylvania's development as an iron-making center during the early decades of the 1800s sets the stage for the area's transformation into a steel-making center by the century's end. The furnace remains, therefore, can be regarded as technological ancestors of the sprawling steel mills whose operations shaped both the landscape of this region and the lives of its residents.
