The Story
From 1863 to 1929, quarries near Hummelstown cut a rich, even-grained brownstone prized by builders across the country as a fashionable masonry stone. The Hummelstown Brownstone Company, founded by Allen Walton, drew immigrant stone-cutters and laborers whose skilled hands shaped the blocks that faced churches, rowhouses, and public buildings far beyond Pennsylvania.
Why it matters
Hummelstown brownstone helped clothe the streetscapes of Gilded Age America, and its quarries are a reminder of how immigrant craftsmanship literally built the nation's cities.
The story behind this marker
AI contextThe era
In the decades after the Civil War — the Gilded Age — American cities grew at a furious pace, and they grew upward and outward in stone. Builders and architects of the era prized a warm, reddish-brown sandstone known as brownstone, whose even grain and rich color came to define whole neighborhoods of churches, rowhouses, and public buildings. The very word "brownstone" became shorthand for a certain kind of city street.
All that stone had to come from somewhere, and quarrying was one of the era's essential heavy industries. Near Hummelstown, beginning in 1863, quarrymen opened seams of especially high-quality brownstone and worked them for more than six decades, into 1929.
This was also an age of immigration, when workers from across Europe filled America's mines, mills, and quarries. The Hummelstown quarries were part of that story too — an industrial site whose fortunes rose and fell with the building booms of a rapidly urbanizing nation.
People & events
The enterprise here was the Hummelstown Brownstone Company, founded by Allen Walton. The company cut stone prized enough that it was sold across the nation as a preferred masonry material — the kind of endorsement, from builders far beyond Pennsylvania, that turns a local quarry into a national supplier.
The work depended on skill, not just muscle. The company employed immigrant skilled stone-cutters alongside laborers, and it was those trained hands that turned rough quarried blocks into the dressed, squared stone a builder could actually use. Quarrying and stone-cutting were demanding, sometimes dangerous trades, and the men who mastered them were craftsmen in the fullest sense.
From 1863 to 1929 the quarries kept up their long run, tracking the appetite of a building nation. When tastes and construction methods eventually changed and the demand for brownstone faded, the quarrying here came to its close.
Its place in the American story
Hummelstown brownstone is a case study in how local resources built distant cities. Stone cut near this Pennsylvania town traveled outward to face buildings around the country, meaning that a piece of this ground is embedded, quite literally, in the streetscapes of Gilded Age America.
The marker also honors something easy to overlook: the immigrant craftsmanship that made it possible. The nation's late-nineteenth-century construction boom rested on the skilled hands of newcomers, and the stone-cutters here are a tangible reminder that America's cities were built by immigrant labor as much as by architects' drawings.
And it captures the arc of an industry. A quarry that opened in the Civil War era and closed at the threshold of the Great Depression traces the whole life cycle of a Gilded Age material — born with a building boom, sustained for generations, and eventually left behind as the country built differently.
If you visit
Approach this as a stop about the raw material of history. We usually admire finished buildings; here you stand at the source, where the stone itself was pried from the earth. It's a chance to think backward from a facade to the quarry floor.
Let the dates do their work — 1863 to 1929. That's more than six decades of steady labor in one place, spanning several generations of workers. The marker turns an ordinary patch of ground into evidence of a long-running industry that most travelers would otherwise pass without a thought.
If you're exploring the Hummelstown area, this is a satisfying stop for anyone who loves architecture or industrial history. Read the marker, then carry its lesson with you: the next brownstone building you see, near or far, is the end of a story that could easily have begun at a quarry like this one.

Lebanon County
Lebanon, PA · est. 1982
Lebanon County was organized in 1813 from parts of Dauphin and Lancaster counties, though the community here reached back much further — its township dated to 1729 and the town of Lebanon to around 1740. Settled largely by Pennsylvania Germans, the area grew into a landscape of prosperous farms and closely held religious traditions. That blend of rich agriculture and faith gave the county an enduring identity rooted in its early settlers' values.
Baron Stiegel
Manheim, PA · est. 1947
In the mid-1700s, German immigrant Henry William Stiegel — known in his heyday as "Baron" Stiegel — turned a Lancaster County iron furnace into one of colonial America's most ambitious industrial ventures, laying out the town of Manheim in 1762 and opening a celebrated glassworks two years later. His fine flint glass rivaled European imports and made his name, even as his lavish living later ruined him. His famous gift of church land carried a nominal rent of one red rose a year, a token still paid to his heirs.
Revolutionary War Gun Factory
Hummelstown, PA · est. 2012
When British troops seized Philadelphia in 1777, Pennsylvania's revolutionary government fled westward and needed weapons for the fight. Near Hummelstown it set up its official state gun factory, working in secret from 1777 to 1779 to turn out muskets and rifles for the Continental Army. In an age when a single skilled gunsmith might finish only a few arms a month, the concentrated production here was a small but vital arsenal for a cause perpetually short of firepower.
Union Canal
Derry Township, PA · est. 1948
First imagined by William Penn and surveyed as early as 1762, the Union Canal finally opened to traffic in 1828, connecting the Susquehanna River at Middletown with the Schuylkill at Reading. For a few decades its boats carried coal and goods across the Pennsylvania interior before the railroads rendered it obsolete. Abandoned in 1885, its overgrown remains can still be seen near Union Deposit, just to the north of the marker.
