Iron, Steel & Industry

Iron, Steel & Industry

Countdown to July 4 2026

Early iron furnaces and forges flourished in the region and were the birthplace of Pennsylvania’s three centuries of industrial prominence. This theme interprets stories of the region’s iron and steel industries, the landscapes and communities they developed, and how they influenced Pennsylvania and the nation.

Chester County’s iron industry developed in the early 18th century and was prominent within the region. Over the decades, the iron industry spread west across Pennsylvania as the Commonwealth developed into a national and internationally known powerhouse in iron, steel, and manufacturing.

Chester County’s iron industry supplied war materials and munitions for the American Revolution and the Civil War. (The theme is closely intertwined with The Philadelphia Campaign.)

Chester County’s industrial beginnings have continued to develop through industrial innovations and technology leadership.
