Biery's Port
Catasauqua, Lehigh County, Pennsylvania
Marker Inscription
First structure, a grist mill, was built about 1752. Starting 1801, Frederick Biery developed the area commercially; erected several landmark stone buildings. This is the oldest part of Catasauqua (incorporated 1853) which was an early home to the anthracite iron industry.

The Story
The story of Catasauqua begins here, where a grist mill first turned around 1752. Starting in 1801, Frederick Biery developed the area into a commercial hub and raised several enduring stone buildings. This oldest corner of the town, incorporated in 1853, became an early cradle of the anthracite iron industry that would help forge industrial Pennsylvania.
Why it matters
Biery's Port marks the roots of anthracite iron-making, a technology that powered America's industrial rise in the nineteenth century.
The story behind this marker
AI contextThe era
This marker sits in the oldest corner of Catasauqua, in the Lehigh Valley of eastern Pennsylvania — a landscape that would become one of the crucibles of American heavy industry. But the story here begins long before the smokestacks, in a quieter agricultural world.
The first structure on this ground was a grist mill, built around 1752. A mill was the natural first anchor of an early settlement: it drew on water power, gave surrounding farmers a place to grind their grain, and became a gathering point around which a community could form.
From that modest beginning the place grew. Starting in 1801, the area was deliberately developed into a commercial hub, and Catasauqua itself was formally incorporated as a town in 1853 — the arc from a single mill to an organized industrial town spanning roughly a century.
People & events
The figure at the center of this transformation is Frederick Biery. Beginning in 1801, he set about developing the area commercially, turning a mill site into something more like a working village.
His most visible legacy was in stone. Biery erected several landmark stone buildings — substantial, permanent structures of the kind that signaled a place meant to last and to do serious business. That he built in stone rather than in more temporary materials tells you something about his ambition for the settlement.
This cluster of early building became the seed of Catasauqua. When the town was incorporated in the mid-1800s, this was its oldest part — the original core from which the later, busier industrial town would spread outward.
Its place in the American story
What lifts this local origin story onto the national stage is what Catasauqua became: an early home of the anthracite iron industry. That single phrase connects this quiet mill site to one of the great turning points in American economic history.
Anthracite — the hard, clean-burning coal of eastern Pennsylvania — helped solve one of the central problems of early industry: how to smelt iron in large, reliable quantities. Iron made with anthracite fed the rails, machines, bridges, and buildings of a rapidly industrializing country, and the Lehigh Valley sat at the heart of that development.
So the ground this marker occupies represents a beginning in two senses. It was the beginning of Catasauqua as a settlement, and the town it grew into was among the beginnings of an iron industry that helped power America's nineteenth-century industrial rise. The mill of 1752 and the ironworks of a century later are two ends of the same thread.
If you visit
Approach this spot as the taproot of a whole town. What you're standing in is the original settlement — the place everything else in Catasauqua grew out from — so it rewards a walker who reads the streets as layers of time.
Look for the older stonework in the neighborhood, the kind of solid, early construction Frederick Biery favored. Set against the later industrial character of the Lehigh Valley, those early buildings mark the transition from a farming mill-village to an iron town, and standing among them you can feel both eras at once.
It makes a rewarding stop on a route exploring the industrial heritage of eastern Pennsylvania. Begin here, at the mill site and the oldest streets, and you'll have the right starting point for understanding how a small water-powered beginning helped grow into a chapter of America's industrial story.

Dery Silk Mill
Catasauqua, PA · est. 1998
Beginning in 1897, D. George Dery built his first Pennsylvania silk mill here in Catasauqua and rapidly expanded across the state. By 1914 his operation spanned fifteen mills and employed thousands, making him one of the world's largest silk manufacturers during the industry's Pennsylvania heyday. The empire proved fragile, and operations ceased in 1923.
George Taylor (1716-1781)
Catasauqua, PA · est. 1947
George Taylor, an Irish-born ironmaster who rose from indentured labor to prosperity, made his home in this handsome 1768 house along the Lehigh. Elected to Pennsylvania's provincial Assembly in 1764, he stood against royal government and was sent to the Continental Congress in July 1776, where he added his name to the Declaration of Independence. His restored home is today a National Historic Landmark.
Davies and Thomas Company
Catasauqua, PA · est. 2023
Founded in the iron-rich Lehigh Valley in 1865, the Davies and Thomas Company mastered a demanding new craft: casting the heavy iron plates that line tunnels bored beneath rivers and cities. Its segments went into landmark works of American infrastructure—the Holland and Lincoln tunnels and railroad bores—as well as projects overseas. A sample of its tunnel lining was proudly displayed at the 1904 St. Louis World's Fair.
Crane Iron Works
Catasauqua, PA · est. 1997
On the Fourth of July, 1840, Welsh ironmaster David Thomas fired up a furnace in Catasauqua that finally proved anthracite coal could smelt iron on a commercial scale. Earlier attempts had failed, but Thomas's hot-blast furnace for the Lehigh Crane Iron Company soon turned out 50 to 60 tons of pig iron a week, and the works grew to six furnaces before closing in 1930. The success helped shift American iron production away from charcoal and toward the hard coal of Pennsylvania's mountains.
