Many of America's most impressive structures--from the Chrysler Building to the George Washington Bridge to the Panama Canal--as well as its battleships, railroads, and automobiles had their origins in the Bethlehem Steel plant in eastern Pennsylvania. Although still in operation, much of the plant, which stretches nearly five miles and comprises hundreds of interlinked buildings, is now being torn down. Photographer Andrew Garn has been documenting this industrial leviathan for more than five years. His photographs, reproduced here in duotone, capture the essential quality of this potent symbol of our industrial heritage. Also included are archival images and drawings, and a brief history by Lance Metz, the foremost authority on the plant. This is the third title in our series on icons of industrial America, following "Wood Burners" and "Grain Elevators."
