Alleghany Furnace
Altoona, Blair County, Pennsylvania
Marker Inscription
Here in 1811, Andrew Henderson and Robert Allison built the second iron furnace in present Blair County. Elias Baker became three-fourths owner in 1836, and in 1844 (as he prepared to build his Greek Revival mansion nearby) he became full owner. The stone store building here was erected about 1837. Until the furnace closed in 1884, it remained in the Baker family, which consistently spelled its name "Alleghany."

The Story
Raised in 1811, the Alleghany Furnace was among the earliest ironworks in what became Blair County, part of the charcoal-iron industry that spread through Pennsylvania's mountains in the early republic. Elias Baker acquired full ownership by 1844 and built a Greek Revival mansion nearby, tying the furnace to a prosperous ironmaster's household that ran it until it went cold in 1884. The surviving stone store building, erected around 1837, still marks the site of this vanished industrial world.
Why it matters
Pennsylvania's charcoal iron furnaces powered the nation's early industrial growth, and sites like Alleghany show how a single family's fortunes rose and fell with the rhythm of American iron.
The story behind this marker
AI contextThe era
In the early 1800s, the ridges and valleys of central Pennsylvania were being remade by iron. The land that would become Blair County sat in a sweet spot for the trade: mountains thick with hardwood for charcoal, streams to power bellows, and ore close enough to the surface to dig. When Alleghany Furnace was raised in 1811, the young United States was still importing much of its finished iron, and every new furnace in the Pennsylvania mountains was a small act of self-reliance.
This was the age of the charcoal-iron "plantation" — not a single machine but a whole working community. A furnace needed woodcutters, colliers to char the wood, teamsters, ore diggers, and founders who knew how to read the color of molten metal. Around each stack grew a cluster of buildings: the furnace itself, a store, workers' housing, and the ironmaster's home. The site here was one of the earliest of these operations in the region.
By the middle of the century, the coming of the railroad and the rise of nearby Altoona would transform this corner of Pennsylvania into one of the great industrial districts in the country. Alleghany Furnace belonged to the generation just before that boom — the charcoal era that laid the groundwork, quite literally, for the iron age that followed.
People & events
The furnace began as a partnership. In 1811, Andrew Henderson and Robert Allison built what became the second iron furnace in the area, gambling their labor and capital on the region's raw materials. Founding a furnace was no small undertaking; it meant assembling land, ore rights, timber, and a skilled workforce before a single bar of iron could be sold.
The name most tied to this place, though, is Elias Baker. He bought a three-fourths share in 1836 and became sole owner in 1844 — the same period in which he prepared to build a Greek Revival mansion nearby. That timing tells a story of its own: the profits of iron were being turned into the stone and columns of a prosperous household. An ironmaster like Baker was part industrialist, part landed gentleman, and his home was meant to announce his standing.
One small, human detail sets this family apart. The Bakers held the furnace for decades, and through it all they kept spelling the name "Alleghany" — their own chosen form, preserved on the marker to this day. It's the kind of stubborn particularity that reminds you real people, with their own habits and pride, stood behind these industrial names. The furnace stayed in the family until it finally went cold in 1884.
Its place in the American story
For much of the nineteenth century, iron was the backbone of American ambition — the stuff of rails, tools, stoves, bridges, and machines. Before the great coke-fueled mills of Pittsburgh dominated the trade, thousands of small charcoal furnaces scattered through the Appalachian ridges did the essential early work. Pennsylvania led the nation in this industry, and sites like Alleghany were the cells that made up that larger body.
The arc of this one furnace mirrors the arc of the industry itself. It rose in the confident years of the early republic, passed into the hands of a single ambitious family during the country's industrial adolescence, and closed in the 1880s, when newer technology and larger plants made the old charcoal method obsolete. A furnace that could not keep up simply went dark.
That rise and fall is a national pattern written in local stone. The fortunes of ironmaking families were bound to markets, fuel, and technology they could not always control — and when the era ended, whole communities that had grown up around a furnace had to find a new reason to exist.
If you visit
What survives here is quieter than the roar of a working furnace, and that quiet is part of the appeal. The stone store building, put up around 1837, still stands as a tangible link to the era — the kind of solid, practical structure that once anchored a busy industrial settlement. Stand near it and try to imagine the smoke, the heat, the wagons, and the constant labor that filled this ground.
Think, too, about the landscape itself. The furnace was placed where wood, water, and ore came together, so look at the hills and streams around you as the resources that made this spot worth choosing. The nearby mansion the ironmaster built speaks to the wealth iron could generate for those at the top.
If you're building a road trip around Pennsylvania's industrial past, this is a fine early chapter — a charcoal-era site that predates the giant mills most people picture. Pair it with a slow look at the surrounding Blair County countryside, and you'll feel how completely a single industry once shaped these mountains.

Baker Mansion
Altoona, PA · est. 1947
Baker Mansion is a striking Greek Revival house built in 1846 for Elias Baker, one of the region's leading ironmasters in the era when Pennsylvania's charcoal-fired furnaces helped forge the nation's iron. Its columned dignity reflected both the wealth and the ambitions of the industrialists who ran the Juniata Valley iron trade. The house now serves as the museum and home of the Blair County Historical Society.
Altoona
Altoona, PA · est. 1947
Altoona was born of the railroad, laid out in 1849 as the mountain-base terminal from which the Pennsylvania Railroad pushed its tracks westward over the daunting Allegheny front. Within a generation the town's yards and shops made it one of the great railroading centers of the nation. In 1867 it hosted a War Governors' Conference, one of several wartime and postwar gatherings that made the city a meeting ground for state leaders.
Pennsylvania Railroad Shops
Altoona, PA · est. 1996
In 1850 the Pennsylvania Railroad laid its first track to Altoona and built its first repair shops there, and the town grew up around the industry. Nestled at the foot of the Allegheny grade, Altoona became the beating mechanical heart of the mightiest railroad in America. By 1925 it held the nation's largest concentration of railroad shops, where some 16,500 workers built and mended the locomotives and cars that moved the country.
