Juniata Iron
Worth Township, Centre County, Pennsylvania
Marker Inscription
Along the streams of this region are ruins of many charcoal iron furnaces and forges built between 1790-1850. Juniata iron was the best in America. Its reign ended with the rise of coal and coke iron making.

The Story
Between 1790 and 1850 the streams of this region powered dozens of charcoal furnaces and forges, and the metal they produced—known as Juniata iron—was reckoned the finest in America. Its ruins still line the valleys, silent monuments to a once-thriving trade. The industry's long reign came to a close as coal- and coke-fired methods overtook the older charcoal process.
Why it matters
Juniata iron represents an entire chapter of American industrial history, when Pennsylvania's forests and streams made it the nation's ironmaking heartland before the coal age transformed the trade.

Scotia
Patton Township, PA · est. 1954
About two miles from this marker, Andrew Carnegie established the iron center of Scotia in 1881, part of the vast industrial empire that made him a titan of the Gilded Age. Workers' houses went up, a railroad was laid, and machinery was set to work extracting and processing iron ore to feed Carnegie's steelmaking. Today only scattered remains survive of a place that once bustled with industry.
Plumbe Forge
Rush Township, PA · est. 1969
About six-tenths of a mile north lie the ruins of an iron forge built by Dr. John Plumbe in 1828, where workers hammered pig iron into "blooms" — semi-refined bars of wrought iron. The raw pig iron was hauled in by mule from the Bald Eagle Valley, a reminder of how rugged and costly moving materials was in early industrial Pennsylvania. The expense of carting the finished iron to the Pennsylvania Canal finally forced the forge to shut down in 1842.
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.
Centre Furnace
College Township, PA · est. 1947
In 1792 Colonels John Patton and Samuel Miles fired up the region's first charcoal iron furnace here, and a later stack kept the fires burning from 1825 to 1858. The operation was part of a booming central-Pennsylvania iron district that made "Juniata iron" a byword for quality. In this era Centre County stood at the forefront of American iron production.
