York Iron Company Mine
North Codorus Township, York County, Pennsylvania
Marker Inscription
Site of the last visible remains of an industry that had a major impact on SW York County. This mine opened in 1854-- the year iron ore was first discovered nearby-- and was later purchased by York Iron. At the industry''s height, 15 mines were in operation here, bringing hundreds of skilled miners from England and Wales. Rising prices and cheaper iron elsewhere caused the mines to close by 1888.

The Story
When iron ore was discovered nearby in 1854, mining took hold across southwestern York County, and this site preserves the last visible remains of that vanished industry. At its peak some 15 mines were working here, drawing hundreds of skilled miners from England and Wales to the Pennsylvania countryside. Rising costs and cheaper iron from elsewhere shut the operations down by 1888.
Why it matters
The mines drew experienced Welsh and English labor into rural Pennsylvania, a reminder that the raw materials — and skilled immigrant hands — behind America's iron age came from many small, now-forgotten local diggings.
The story behind this marker
AI contextThe era
In the decades around the Civil War and the Gilded Age that followed, America was hungry for iron. It went into rails, machinery, tools, and the framework of a fast-industrializing nation. That appetite sent prospectors and companies searching for ore wherever it could be found — including the rolling farmland of southwestern York County, Pennsylvania.
This was not the age of a few giant mines but of many small ones. Local ore deposits, once discovered, could turn a quiet rural district into an industrial hive almost overnight. The countryside here became one of those places, its fields and hollows suddenly valuable for what lay beneath them.
Mining also meant people. Extracting and processing iron ore took specialized knowledge, and the districts that boomed drew skilled workers from far away — reshaping the human landscape of the region as surely as the pits reshaped the ground.
People & events
The story here begins in 1854, the year iron ore was first discovered nearby and this mine opened. In time it passed into the hands of the York Iron Company, whose name the site still carries. What started with a single discovery grew into a genuine industry.
At its height, fifteen mines were working this district at once. To run them, the operations drew hundreds of skilled miners from England and Wales — men who brought hard-won expertise from the old mining regions of Britain to the Pennsylvania countryside, and who put down roots in a place far from home.
But mining lives and dies by price. As costs rose and cheaper iron became available from elsewhere, the local operations could no longer compete, and the mines closed by 1888. This site holds the last visible remains of an industry that once defined the corner of the county around it.
Its place in the American story
It's easy to picture America's iron age as a matter of famous furnaces and titan companies. The York Iron Company Mine tells the other half of the story: the raw material behind the nation's rails and machines came in large part from countless small, local diggings like this one, scattered across the countryside and now mostly forgotten.
It's also a chapter in the American immigrant story. The skilled hands that made these mines work came from England and Wales, part of the broad current of experienced European labor that flowed into the United States to build its industrial economy. The knowledge that once powered British mining helped power America's.
And the ending is as American as the boom. When cheaper iron appeared elsewhere, the market moved on and the district emptied out — a familiar cycle of rise and decline that played out in resource towns across the country.
If you visit
Come here for the quiet after the boom. This site preserves the last visible remains of an industry that once filled these hills with the sound of fifteen working mines — and the contrast between that past and the peaceful countryside today is the whole point.
As you look over the landscape, picture the hundreds of English and Welsh miners who arrived with their skills and made lives here, and the ore that left this ground to become the iron of a growing nation. What's left is subtle; let the marker do the work of populating the scene for you.
It makes a rewarding stop on a back-roads drive through southwestern York County. Pair it with the region's small towns and farmland, and you'll see how completely a place can hold the memory of an industry that vanished well over a century ago.

Birthplace of Commercial Ice Cream Production
Seven Valleys, PA · est. 2012
In 1851 C. Jacob Fussell built a factory near here to turn the surplus milk and cream of York County's dairy farmers into ice cream—the first time the treat was mass-produced for commercial sale in the United States. The nearby Northern Central Railroad carried his product straight to the Baltimore market. After Fussell relocated to Baltimore, local makers kept the trade alive into the 1940s.
York Imperial Apple
York Township, PA · est. 1948
On the nursery grounds of Springwood Farms, orchardist Jonathan Jessop propagated a new apple in 1820 that kept firm and crisp through a long winter's storage. Decades later, in 1855, it took the name "York Imperial," and its keeping quality carried it into orchards across the country as one of America's leading commercial varieties. A single tree's chance seedling became a fixture of the nation's fruit trade.
York Inter-State Fair
West Manchester Township, PA · est. 1978
The York fair traces its origin to a charter granted by the Penn family in 1765, making it a claimant to the title of America's oldest agricultural fair. After lapsing in 1815, it was revived in 1853 by the York County Agricultural Society and has run every year since, settling onto its present grounds in 1888. For generations it has gathered farmers to show livestock, crops, and the season's best work.
Golden Plough Tavern
York, PA · est. 2002
Built around 1741 by Martin Eichelberger in the earliest days of what would become York, the Golden Plough Tavern is a rare survivor of the medieval-style half-timber construction that German immigrants carried across the Atlantic. Its exposed timber framing, filled with masonry, reflects building traditions centuries old in the Rhineland but almost unknown in the English colonies. For generations it served travelers as a tavern along the colonial frontier of Pennsylvania.
