Centre Furnace
College Township, Centre County, Pennsylvania
Marker Inscription
Here Cols. John Patton and Samuel Miles operated the first charcoal iron furnace in the region, 1792-1809. Present stack used 1825-1858. In this era Centre County led in the making of Juniata iron.

The Story
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.
Why it matters
Centre Furnace marks the beginnings of an industry that powered the early republic's growth and left central Pennsylvania dotted with the stone stacks of a vanished iron economy.
The story behind this marker
AI contextThe era
In the decades right after American independence, the country ran on iron — and much of that iron came from the forested hills of central Pennsylvania. The region had the three things a charcoal furnace needed: ore in the ground, limestone for flux, and endless hardwood to burn into charcoal. Where those met, ironmasters built.
The 1790s and early 1800s were the opening chapter of this story. Furnaces were being blown into blast across the Pennsylvania interior, each one the center of its own small industrial world — a stone stack, workers' housing, charcoal hearths, and roads to haul the finished metal out.
Centre Furnace stands at the very start of that chapter for this region. When its fires were first lit, it was the first charcoal iron furnace in the area — a pioneering venture in a landscape that would soon become one of the young nation's great iron districts.
People & events
The furnace was established by two Revolutionary-era colonels, John Patton and Samuel Miles, who operated it from 1792 to 1809. The military title was common among the founders of these enterprises — men who had served in the Revolution and afterward turned their ambition toward building the economy of the new republic. Iron-making suited that ambition: it was capital-intensive, demanding, and, when it worked, richly rewarding.
Running a charcoal furnace was a relentless business. Once a furnace was “in blast,” it burned around the clock for months, devouring charcoal and ore and requiring a small army of woodcutters, colliers, fillers, and founders. A furnace was less a machine than a village organized around fire.
The stone stack that survives here belongs to a later phase, in use from 1825 to 1858 — evidence that iron-making at this site continued well beyond its founders' years, carried on by the generations who followed them into the trade.
Its place in the American story
During this era, Centre County was at the forefront of American iron production, and its output earned a name that meant something in the marketplace: “Juniata iron.” Iron from this district was prized for its quality, and a regional reputation like that was real economic power in a country still learning to make things for itself.
That matters to the larger American story. Before the age of coke and steel, before the great mills of later generations, it was charcoal furnaces like this one that supplied the tools, hardware, and iron goods a growing nation depended on. This was heavy industry at a human scale — powered by wood, water, and muscle.
Centre Furnace is where that regional industry began. To stand at its origin point is to stand at the headwaters of an iron economy that, for a time, helped set the standard for the entire young United States.
If you visit
Come to see beginnings. This is the site where the region's iron industry started, and even the quiet of the place now is part of the story — a reminder of how completely a once-roaring industry can fall silent.
Look for the language of the old iron world in what remains and in the setting around it: the stack, the water that powered the operation, the woods that fed it charcoal by the wagonload. Try to imagine the noise, heat, and constant labor of a furnace in blast, and the settlement of workers that any such furnace required to keep it running.
On a road trip through central Pennsylvania, this site pairs naturally with the region's other iron landmarks; together they map a vanished industrial geography hidden in what now looks like gentle countryside. Give yourself a few unhurried minutes here to let the scale of that lost world register — this is where it all began for the district.

Centre Furnace - PLAQUE
College Township, PA · est. 1922
This weathered stack is a surviving piece of the ironworks raised in 1792 by John Patton and Samuel Miles, both veteran officers of the Revolution turned frontier industrialists. Its furnace produced the first iron ever smelted in Centre County, hauled out on mule-back over rough mountain trails to the growing market at Pittsburgh. Fired in two long stretches between 1792 and 1858, the works helped anchor the charcoal-iron industry that once thrived across central Pennsylvania.
John I. Thompson Grain Elevator and Coal Sheds
College Township, PA · est. 2006
Built in 1885 by Lemont founder Moses Thompson for his son John, this grain elevator and coal shed complex became a bustling center of trade for Centre County. Grain moved out and coal came in over the Bellefonte, Nittany & Lemont Railroad, later folded into the mighty Pennsylvania Railroad, tying this rural community into the wider industrial economy. The wooden buildings are now rare survivors of a once-common rural commercial form, and Moses Thompson also helped found the school that became Penn State University.
Philip Benner
College Township, PA · est. 1947
Ironmaster Philip Benner made his home at Rock, where he built one of the region's first forges in 1794 along with a nail and slitting mill. A founder of Bellefonte, he became a leading figure in Centre County's affairs until his death in 1832. His works helped establish the iron trade that would define the area for a century.
Philip Benner
Benner Township, PA · est. 1947
In the young republic's early years, central Pennsylvania's forested valleys became iron country, and Philip Benner was among its pioneers. He built one of the region's first forges here in 1794, along with a nail and slitting mill, turning local ore and waterpower into finished iron at a time when the nation was hungry for it. A founder of nearby Bellefonte, he remained a driving force in Centre County affairs until his death in 1832.
