Pennsylvania Furnace
Franklin Township, PA · est. 1947
Established around 1810, Pennsylvania Furnace was one of the many iron works that flourished along the streams of the Juniata region in the early 19th century. It began by smelting ore with charcoal from the surrounding forests, then adapted to coke as fuel technology changed, keeping iron flowing here as late as 1888. The surviving buildings offer a tangible link to nearly a century of ironmaking.
