Centre Furnace - PLAQUE
College Township, Centre County, Pennsylvania
Marker Inscription
This stack is part of the plant of the Centre Iron Company which was erected in 1792 by Col. John Patton and Colonel Samuel Miles, officers in the War of the American Revolution. The product of this furnace was the first iron melted in Centre County and was carried on mule-back to Pittsburgh. The furnace was operated from 1792 to 1809 and from 1825 to 1858.

The Story
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.
Why it matters
It stands for the frontier iron plantations that turned Pennsylvania's forests and ore into the backbone of early American manufacturing.
The story behind this marker
AI contextThe era
In the 1790s, the ridges and valleys of central Pennsylvania were still frontier country. The Revolution was barely over, the young republic was finding its feet, and the land here was rich in two things that mattered enormously to early America: dense hardwood forests and beds of iron ore lying close to the surface.
Those two ingredients, plus limestone and fast water, were exactly what it took to make iron in that age. Long before coal and railroads, iron was smelted with charcoal burned from the surrounding woods, and so ironworks rose wherever forest and ore met. This corner of what would become Centre County was one of those places.
What it lacked was easy access to markets. The mountains that hid the ore also walled it off from the growing towns to the west, and everything made here had to be muscled out over rough, half-made trails.
People & events
The furnace was raised in 1792 by two men who had already given hard service to their country: John Patton and Samuel Miles, both officers in the War of the American Revolution. Like a number of veterans of that war, they turned from soldiering to the risky, capital-hungry business of frontier industry.
Their furnace produced the first iron ever smelted in Centre County — a genuine milestone for the region. And getting it to buyers was an ordeal in itself: the iron was loaded onto mules and carried, load by load, over the mountains to the rising market at Pittsburgh.
The works ran in two long chapters, from 1792 to 1809 and again from 1825 to 1858. That gap and revival tell their own story. Charcoal ironworks lived and died by the price of iron, the supply of nearby timber, and the fortunes of their owners, and few ran without interruption across so many decades.
Its place in the American story
Furnaces like this one were the backbone of American manufacturing before the age of coal and steel. Scattered across the Pennsylvania interior, these "iron plantations" were small, self-contained worlds — furnace, workers' housing, woodlots, and an ironmaster presiding over it all — and together they made much of the metal that built the early United States.
The iron that left here on mule-back became tools, stoves, nails, and the countless everyday objects a growing country needed. In that sense a remote frontier furnace was quietly tied to the whole national project of settlement and expansion.
The long charcoal-iron era eventually gave way to anthracite and coke and to furnaces built beside railroads and coalfields. When it did, works like this one fell silent for good — which is part of why a surviving stack is worth pausing over. It marks the end of one industrial age and the beginning of the one that followed.
If you visit
What you'll find is the weathered stone stack itself — the surviving heart of the old plant. Stand close and it's easy to picture the roar and glow it once held, and the men who fed it around the clock during a "blast" that could run for months.
Look out at the wooded hills around you and imagine them stripped for charcoal, then imagine strings of laden mules setting off westward toward Pittsburgh. The quiet of the place today is the opposite of what it once was.
It makes a rewarding stop on a route through Pennsylvania's iron country, where a string of old furnaces still dot the landscape. Give yourself a few minutes to read the stones, and you'll come away with a real feel for how the young nation turned its forests and hills into iron.

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.
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.
