Oil Creek

Titusville, PA · est. 1954

Long before drilling rigs, Native people of this region gathered petroleum by skimming it from the surface of Oil Creek, where it naturally seeped into the water. In the years from 1859 to 1865, these same banks became the beating center of the world's first oil rush, crowded with wells, derricks, and refineries.

Oil Creek Railroad

Corry, PA · est. 2011

When oil gushed from the ground near Titusville, the frantic problem was how to move it. Opened in 1862, the 27-mile Oil Creek Railroad linked the oil fields to the rail hub of Corry, replacing leaky barrels floated downstream and slow horse-drawn wagons. It hauled staggering volumes of crude, drew waves of fortune seekers to the region, and became one of the most profitable railroads in the country.

Oil Well Supply Company

Oil City, PA · est. 1997

Founded near Oil City in 1878, the Oil Well Supply Company rose to become one of the leading makers of oil-field machinery and supplies, its equipment reaching drillers across the globe. At its height in the early 1900s the firm employed some 2,000 workers, and in 1930 it was absorbed as a subsidiary of the giant U.S. Steel. Its story traces the consolidation of scrappy oil-region enterprises into the era's great industrial combinations.

Oil-Producing Salt Well

Beaver Township, PA · est. 1985

In 1815, drillers here bored into the earth hunting brine to boil down into salt, a precious commodity on the frontier. When the well was deepened in 1819, they struck oil instead—an unwelcome contaminant that soon forced the salt works to close. Decades before the world thought to prize it, petroleum surfaced here as a nuisance, some forty years ahead of Drake's famous 1859 well near Titusville.

Okehocking Indian Town - PLAQUE

Willistown Township, PA · est. 1924

In 1701 William Penn set aside a 500-acre square along Ridley Creek for the Okehocking band of the Unami Lenni-Lenape, moving the chiefs Pokhais, Sepopawny, and Muttagooppa and their people here from the lower Ridley and Crum Creek country. Penn's records describe it as the only formal Indian reservation the proprietor ever established. The tract offered a brief, protected refuge as European settlement steadily pressed in around it.

Old Arch Bridge

Lewistown, PA · est. 1947

This restored stone span was built in 1813 as part of the turnpike linking Harrisburg with Pittsburgh, a vital artery across the Pennsylvania mountains in the early republic. Its builders shaped a stone arch without a keystone—an unusual feat that has kept the bridge standing for more than two centuries. It carried travelers and freight in the age before canals and railroads bound the state together.

Old Brick Capitol

Harrisburg, PA · est. 1953

After Harrisburg became Pennsylvania's capital, the state needed a proper home for its government. Architect Stephen Hills designed and built the first State Capitol here between 1819 and 1821, and lawmakers first gathered inside on January 2, 1822. The dignified brick statehouse served the commonwealth for three-quarters of a century until fire destroyed it in February 1897.

Old Chapel

Bethlehem, PA · est. 1953

In the mid-1700s Bethlehem was a tightly organized Moravian community, and this second place of worship served the congregation from 1751 to 1806. The Moravians were renowned for their sophisticated sacred music, and within these walls prominent leaders of the Revolutionary era heard hymns, chorales, and the Gospel preached by bishops such as Spangenberg and Ettwein. It was a spiritual and cultural center in a settlement that punched far above its size in the young nation's religious and musical life.

Old Court House

Shippensburg, PA · est. 1947

Before Carlisle was chosen as the county seat, justice in the Cumberland frontier was dispensed at 'Widow Piper's Tavern' in Shippensburg, which hosted the county's court sessions in 1750 and 1751. Taverns often doubled as the civic centers of early settlements, serving as courtroom, meeting hall, and lodging all at once. The building endures today as the home of the Shippensburg Civic Club.

Old Courthouse

Gettysburg, PA · est. 1954

From 1804 to 1859, the first courthouse of Adams County stood in Gettysburg's old Center Square, on land given by town founder James Gettys. A county's first courthouse was the heart of its civic life — where justice was administered, records kept, and the young community governed itself in the decades of the early republic. The building is long gone, but the square it anchored remains the center of the town Gettys laid out.

Old Economy

Ambridge, PA · est. 1948

Old Economy was the third and final home of the Harmony Society, a communal religious sect of German immigrants led by George Rapp, who founded the group in 1805. Settling here in 1825, the Harmonists built a prosperous, tightly organized village whose farms, mills, and factories made the celibate community famous for its industry and wealth. The society endured until 1905, and its preserved village is now cared for by the Pennsylvania Historical and Museum Commission.

Old Economy Memorial

Ambridge, PA · est. 1947

In 1805 a band of German Pietist immigrants led by George Rapp organized the Harmony Society, a communal religious sect that held all property in common while awaiting the millennium. After earlier settlements in Pennsylvania and Indiana, they built their final home, Economy, along the Ohio River between 1824 and 1831. Their disciplined communal industry made them famously prosperous until the society dissolved a century later, in 1905.

Old Forge

Old Forge, PA · est. 1947

In 1789, in the years just after the Revolution when the new republic was pushing industry into its river valleys, Dr. William Smith and James Sutton built an iron forge on the south bank of the Lackawanna River. It was the earliest forge in this corner of northeastern Pennsylvania, tapping the region's water power and abundant ore long before anthracite coal made the Lackawanna Valley a national industrial powerhouse. The little settlement that grew up around the works took its name from the forge itself, and the name Old Forge stuck long after the hammer fell silent.

Old Forge Wall of Honor

Old Forge, PA

In the old anthracite-coal country of Lackawanna County, the borough of Old Forge raised this Wall of Honor in 2005 to gather the names of its own — the sons and daughters who left these hills to wear the nation's uniform. Communities like this one, built by immigrant miners and their families, sent generation after generation into the country's wars, and a wall of names is how a small town keeps faith with them. The borrowed phrase "Lest We Forget," older than any single conflict, turns the monument into a standing promise rather than a record of one battle.

Old Franklin County Jail

Chambersburg, PA · est. 1975

Built in 1818 in restrained Georgian style, the Franklin County Jail served Chambersburg for 152 years—among the borough's oldest surviving buildings. Its stone walls stood through one of the Civil War's boldest raids: in July 1864 Confederate cavalry, demanding a ransom the town could not pay, put much of Chambersburg to the torch. The jail endured while blocks around it burned.

Old French Road

Millcreek Township, PA · est. 1946

Long before highways, travelers crossed this high ground on the Presque Isle Portage, the carrying-path that linked Lake Erie to the headwaters flowing toward the Ohio. It formed part of the older Venango Trail worn by Native people through the forests of northwestern Pennsylvania. In 1753 the French widened an Indian path into their military French Road, and the modern highway still shadows and departs from that ancient route here.

Old Garrison

Franklin, PA · est. 1947

By 1796 Fort Franklin had outlived its usefulness, and this new garrison rose at the foot of what is now Tenth Street to take its place, commanding both French Creek and the Allegheny River. U.S. troops held it until 1799, after which it found a second life as the first jail of Venango County. The original site now lies beneath the water.

Old Glassworks

Springhill Township, PA · est. 1955

In the 1790s the western Pennsylvania frontier was still raw country, and glass — fragile and heavy — was among the hardest goods to haul over the mountains. Here, between 1794 and 1797, Albert Gallatin, soon to be Thomas Jefferson's long-serving Treasury Secretary, backed the first glass factory west of the Alleghenies, drawing on trained hands from the noted Amelung works. The little enterprise made window glass and bottles for a growing region until it closed in 1807.

Old Glassworks

Monongahela Township, PA · est. 1955

On this site in 1805 rose the first glass factory west of the Monongahela River, part of the wave of frontier industry encouraged by Albert Gallatin, Thomas Jefferson's Treasury Secretary and a tireless promoter of manufacturing in western Pennsylvania. Furnaces here turned local sand into window glass and vessels for a region hungry for finished goods. Glassmaking continued at the spot until 1849.

Old Haverford Friends' Meeting

Haverford Township, PA · est. 1975

Quakers have gathered on this Haverford site since 1684, in the first years of William Penn's colony founded as a refuge for the persecuted. The oldest part of the present meetinghouse dates to 1700, built onto the original log structure where Penn himself worshipped in late 1699. Few places so directly connect to the founder of Pennsylvania and the Friends who shaped its tolerant beginnings.

Old Jail

Lancaster, PA · est. 2015

Lancaster's colonial jail once stood just north of this spot, serving the county from 1753 to 1851. In December 1763, the last surviving members of the Conestoga—a small community descended from the once-powerful Susquehannock—were sheltered here for their own safety. A frontier mob known as the Paxton Boys broke in and murdered them, and no one was ever charged for the killings.

Old Log Building

Waynesboro, PA · est. 1955

Built by John Bourns sometime between 1770 and 1780, this modest one-and-a-half story log structure served the young community as both schoolhouse and church — the twin pillars of frontier civic life. In an age when a single sturdy building often had to do double duty, learning and worship shared the same walls. It later became a private dwelling and endures as one of the oldest buildings in Waynesboro.

Old Log Church

Napier Township, PA · est. 1974

On land donated by John Schell, the German Reformed and Lutheran families of this Bedford County valley raised a plain log meetinghouse in 1806, sharing it as a "union church." Such joint congregations were common on the early Pennsylvania frontier, where scattered settlers of the two German Protestant traditions pooled their labor to build a single house of worship. The rough-hewn structure reflected the practical faith of the Pennsylvania Germans who settled the backcountry.

Old Salem Church

Harrisburg, PA · est. 1968

When John Harris's settlement at the Susquehanna crossing was still a scattering of cabins, its first congregation gathered in a log meeting house raised in 1787 — the earliest church in what would become Pennsylvania's capital. Land set aside for worship by the Harris family anchored the community, and by 1822 a permanent brick sanctuary had replaced the logs. The marker traces the young town's spiritual and civic roots in the decades just after independence.

Old St. Joseph's Roman Catholic Church

Philadelphia, PA · est. 2014

In 1729, Jesuit priest Joseph Greaton established the earliest Catholic foundation in Pennsylvania, and by 1733 a church stood here in a colony that granted rare tolerance to Catholics. Greaton was for a time the only Catholic priest in Philadelphia. From this parish, Jesuits went on to found frontier missions in Adams and Berks counties and the first Catholic churches in New Jersey and Delaware.

Old St. Luke's Church

Scott Township, PA · est. 2001

After the French and Indian War, veteran Maj. William Lea founded this congregation on his land grant, making it the oldest Episcopal church in southwestern Pennsylvania, with Francis Reno as first vicar. Its members included Gen. John Neville, the deeply unpopular federal tax collector whose office helped spark the 1794 Whiskey Rebellion that convulsed the surrounding country. A revival of interest in 1852 produced the stone church that stands today, home to an 1823 English pipe organ said to be the first carried over the Alleghenies.

Old St. Mary's Roman Catholic Church

Philadelphia, PA · est. 2013

Founded in 1763, Old St. Mary's rose in a colonial city where anti-Catholic feeling still ran strong, standing as proof of the unusual tolerance William Penn had written into Pennsylvania's founding. As the first Roman Catholic cathedral in the colony, it welcomed worshippers at a time when their faith was suspect elsewhere in America. During the Revolution, members of the Continental Congress attended services here, honoring Catholic France and Spain, whose aid proved vital to the fight for independence.

Old State Line

McKean, PA · est. 1946

Before 1792, Pennsylvania's northern edge ran right across this ground, and the land above it belonged to no state's settled claim. That year Pennsylvania bought the wedge known as the Erie Triangle, paying just over $151,000 to gain a genuine harbor on the Great Lakes. Without that purchase, the state would have been boxed out of Lake Erie entirely.

Old State Line

Waterford Township, PA · est. 1946

This spot once sat on Pennsylvania's original northern boundary, the line that hemmed the state in before 1792. In that year the commonwealth paid more than $151,000 for the Erie Triangle, buying itself a foothold and a port on Lake Erie. The old line, long erased from maps, still crossed the highway here within living memory of the marker's makers.

Old State Line

Girard, PA · est. 1946

Here the highway crosses what was once the top of Pennsylvania, the northern boundary that stood before the state reached Lake Erie. In 1792 Pennsylvania purchased the Erie Triangle for over $151,000, extending its territory to the lakeshore and its all-important harbor. The transaction turned a landlocked corner into a gateway.

Old State Line

Springfield Township, PA · est. 1946

Before 1792 this was the literal edge of Pennsylvania, its northern line running across the road at this point. The state then bought the Erie Triangle for more than $151,000, gaining both the tract and the Lake Erie port that came with it. What had been a boundary became the middle of a growing commonwealth.

Old State Line Historical Marker

Wattsburg, PA

In the young republic's first decades, Pennsylvania's northern line ran right across this road—until 1792, when the state secured the wedge of land known as the Erie Triangle. That purchase, for which Pennsylvania paid the federal government the oddly precise sum of $151,640.25, gave the commonwealth something no other arrangement could: its own frontage on Lake Erie and a deep-water port at Presque Isle. This unassuming spot near Wattsburg marks where the old boundary once lay, before the map was redrawn to reach the Great Lakes.

Old State Road (Milesburg to Waterford)

DuBois, PA · est. 1955

Opened to the Allegheny River in 1804, the Old State Road was the first route to Pennsylvania's northwestern frontier, and in this section it traced the course of the older Chinklacamoose Path used by Native travelers. During the War of 1812 it carried troops under Major McClellan toward the fighting at Erie. Where the modern highway crosses here, it meets the line of that pioneering road.

Old Stone Fort

Matamoras, PA · est. 1948

Around 1740, when the upper Delaware valley was a raw and contested frontier, Dutch settler Simon Westfael raised a sturdy stone house here that neighbors could flee to when violence flared. Structures like this doubled as homes and fortifications in an era when European farming families lived amid the tensions of frontier warfare. Local memory long called it the Old Stone Fort, or Fort Matamoras.

Old Stone House

Brady Township, PA · est. 1968

Built in 1822, this stone building served as a wayside inn for travelers crossing the young state's interior, offering rest and shelter along a frontier road. Such inns were vital hubs of early travel, where news, trade, and hospitality met at the day's end. Reconstructed in 1963, it recalls the era when overland journeys were slow and a roadside stop was a welcome sight.

Old Swedish Burial Ground

Chester, PA · est. 1954

This ground in Chester marks the site of the first St. Paul's Episcopal Church, built in 1702 in one of Pennsylvania's oldest settlements with roots in New Sweden. Just south lies the grave of John Morton, the Pennsylvania delegate whose vote helped tip the colony toward independence and who signed the Declaration of Independence.

Old Waterworks

Bethlehem, PA · est. 1953

As early as 1754 the Moravians of Bethlehem engineered one of colonial America's earliest municipal water systems, pumping spring water uphill to a tower and letting gravity feed it to a network of cisterns. The pipes were bored from hollowed tree trunks, a practical marvel of frontier ingenuity that delivered running water to the community decades before most American towns had anything like it. The original engine house still stands nearby as a reminder of this early feat of engineering.

Old Woolen Factory

Forksville, PA · est. 1951

A short distance southeast along Loyalsock Creek, Samuel Rogers, Jr. established a factory in 1810 that put the region's water power to work. During the War of 1812 it wove kersey — a coarse, sturdy woolen cloth — to clothe American soldiers, tying this remote valley to the national war effort. A flood in 1816 halted the works, cutting short one of the area's earliest industrial ventures.

Oldest Oil Producing Well

Cornplanter Township, PA · est. 1958

Drilled in 1861, just two years after Edwin Drake's famous well launched the modern oil age nearby, the McClintock No. 1 has produced oil continuously ever since. Sunk into the Venango County fields at the very birthplace of the petroleum industry, it stands only about 240 yards from the Drake site. Its remarkable longevity makes it a living link to the frantic first years of the American oil boom.

Oldest Photograph

Philadelphia, PA · est. 1989

Only weeks after Louis Daguerre unveiled his photographic process in France, an American set out to try it for himself. Around September 25, 1839, Joseph Saxton of the U.S. Mint rigged a cigar box and a crude lens to capture an image of Philadelphia's Central High School. The small, faint picture that resulted is the earliest surviving photograph made in the United States.

Ole Bull's Colony

West Branch Township, PA · est. 1947

In 1852, the celebrated Norwegian violinist Ole Bull bought more than eleven thousand acres of Pennsylvania wilderness to build a utopian refuge for his countrymen. He laid out settlements with hopeful names — New Norway, Oleona, New Bergen, Walhalla — and began a castle on a mountain ridge. The dream faltered within a few years amid poor soil and tangled land titles, leaving the villages and Ole Bull's Castle as haunting remnants of an immigrant colony that never was.

Olean Road

Corsica, PA · est. 1950

The Olean Road, an early route running from Olean to Kittanning, followed the older Catawba Path — a trail once used by Five Nations (Iroquois) war parties on their long raids against the Catawba people of South Carolina. Near this point it crossed another Native path linking Venango (present-day Franklin) with Chinklacamoose (present-day Clearfield). The layered names on the land record centuries of Indigenous travel and warfare before settlers ever arrived.

Oley Moravians

Oley Township, PA · est. 1948

Around 1748 the Moravians — German-speaking Protestants known for their zeal for education — erected a building in the Oley Valley to serve as both church and school. Here they ran a boarding school from 1745 to 1751, part of a wider Moravian network of learning that spread across colonial Pennsylvania, and later built a schoolhouse in 1776 that has since vanished. Their commitment to teaching set them apart on a frontier where formal schooling was scarce.

Oliver Pollock (1737-1823)

Hampden Township, PA · est. 2018

A Scots-Irish immigrant, Oliver Pollock built a merchant fortune — in part through the slave trade — and poured the modern equivalent of millions into the American Revolution. Convinced that the young nation's future lay in the West, he worked to open trade along the Mississippi River, channeling arms and supplies to the frontier and financing George Rogers Clark's Illinois Campaign. The crushing debts he took on for the cause led to imprisonment and the loss of much of his wealth; he spent his later years, from 1792 to 1806, living here in Cumberland County.

One Red Rose - Caspar Wistar PLAQUE

Jackson Township, PA · est. 1930

In 1738 Philadelphia glassmaker Caspar Wistar gave one hundred acres to a congregation of German Reformed families among the Tulpehocken settlers, asking in return only one red rose paid each year. That symbolic rent is still honored by Trinity Reformed Church, a living link to the region's colonial German community. The congregation's roots reached back to 1727, when Reverend John Philip Boehm led its first communion service.

One-Room Schoolhouse

Shippensburg Township, PA · est. 1970

The Mount Jackson, or Potato Point, School was first built in 1865 as one of the countless one-room schoolhouses where a single teacher taught children of every age. Faithfully reconstructed and moved to this site in 1969 by alumni and friends of Shippensburg State College, it preserves a vanishing form of American schooling. Such schools were the backbone of rural education for generations.

Opportunities Industrialization Centers

Philadelphia, PA · est. 1990

In 1964, in the unlikely setting of an abandoned Philadelphia jailhouse, Rev. Leon H. Sullivan opened the first Opportunities Industrialization Center to train Black workers for skilled jobs that discrimination had long kept beyond their reach. Born of the same organizing energy as Sullivan's earlier 'selective patronage' boycotts, O.I.C. paired vocational instruction with dignity and self-reliance, and the model spread from this city to hundreds of centers across the nation and eventually overseas.

Ora Washington (1899-1971)

Philadelphia, PA · est. 2004

For nearly a decade Ora Washington reigned over Black women's tennis, claiming eight national singles titles from the American Tennis Association between 1929 and 1937. When she wasn't dominating the court she starred for the Philadelphia Tribunes, one of the era's great women's basketball teams, and she coached and competed here at the YWCA. Barred by segregation from the mainstream circuits, she built her legend within the parallel world of Black athletics.

Osborne's Hill - PLAQUE

Birmingham Township, PA · est. 1915

From the height of Osborne's Hill, British commander General Sir William Howe watched and directed his army during the Battle of Brandywine on September 11, 1777. The ridge gave him a commanding view as his flanking column swung wide around Washington's right and struck where the Americans least expected. It was, in effect, the British headquarters for the day's decisive maneuver.

Oscar Hammerstein II (1895-1960)

Doylestown, PA · est. 1994

From his farm in the Bucks County countryside, Oscar Hammerstein II helped remake the American musical. Partnering with composer Richard Rodgers, he wove songs directly into story and character in a string of landmark works — South Pacific, The King and I, and The Sound of Music. The rolling landscape around his home is said to have inspired the opening lines of "Oh, What a Beautiful Morning" for Oklahoma! in 1943.

Out of This Furnace

North Braddock, PA · est. 2023

Thomas Bell's 1941 novel Out of This Furnace follows three generations of a Slovak immigrant family in the steel town of Braddock, where the mills ran day and night. Bell drew on his own life—including work at the nearby Edgar Thomson Steel Works—to render the hardships and hopes of immigrant labor with unusual authenticity. The book endures as one of American literature's most vivid portraits of working-class industrial Pittsburgh.

Over the Top

Philadelphia, PA

This Philadelphia memorial honors the young men of the city's Sixth, Eleventh, and Twelfth Wards who served in the First World War — 'the Great War of the Nations,' as a generation that had not yet numbered it called the conflict of 1914–1918. Neighborhood war memorials like this one rose across American cities in the years after the Armistice, funded by local families determined that their sons' service not be forgotten. The very phrasing on the stone captures a world that did not yet know a second, greater war was coming.

Owen Wister (1860-1938)

Philadelphia, PA · est. 2001

Owen Wister, born in the Philadelphia area in 1860, drew on his travels in the American West to write "The Virginian" in 1902, the book that set the mold for the Western novel. Its taciturn cowboy hero and famous line, "When you call me that, smile!", helped fix the image of the rugged, honorable frontiersman in the popular imagination. Though a lifelong easterner, Wister did as much as anyone to turn the cowboy into an American folk hero.

Packer Mansion

Jim Thorpe, PA · est. 1971

Asa Packer arrived in the Lehigh Valley a poor carpenter and left it one of the richest men in America, having built the Lehigh Valley Railroad into an anthracite-coal empire. In 1860 he crowned his fortune with an ornate Italianate mansion overlooking Mauch Chunk (today's Jim Thorpe), and he poured his wealth back into the region—most enduringly by founding Lehigh University in 1865. The house survives with its original furnishings intact, a preserved window into Gilded Age industrial wealth.

Palmerton Area Veteran's Memorial

Palmerton, PA

Dedicated in 2012, the Palmerton Area Veterans Memorial honors all service members from the Palmerton area who have served the United States. The borough grew in the 20th century around the zinc industry in Carbon County's Lehigh Valley, and its veterans served in the World Wars and the conflicts that followed. The memorial gathers that shared sacrifice into a lasting community tribute.

Palmyra & N. Londonderry WWI–WWII Memorial Field

Palmyra, PA

This field in Palmyra was set aside as a living memorial to the men and women of the borough and neighboring North Londonderry Township who served in the two great wars of the 20th century. Dedicating a playing field or park rather than a stone shaft was a common American gesture after these conflicts—a memorial that the community would actually use, tying the sacrifice of its veterans to the everyday life of the town. Pennsylvania's small industrial and farming communities like Palmyra sent a striking share of their young people into uniform, first in 1917–1918 and again in the far larger mobilization of 1941–1945.

Pandenarium

East Lackawannock Township, PA · est. 2019

In November 1854, sixty-three African Americans freed from a Virginia plantation arrived in Mercer County to build a new life. Manumitted by Dr. Charles Everett, they settled an agricultural community on land he provided, where abolitionists had already raised houses to receive them. Many of these newly free men and women went on to labor toward purchasing freedom for others. Archaeology has since recovered the traces of their determined, self-made community.

Parker Kidnapping & Rescue

West Nottingham Township, PA · est. 2011

In 1851, emboldened by the harsh new Fugitive Slave Law, Maryland slave catchers seized Rachel and Elizabeth Parker — two free Black women — from the Nottingham area. When Rachel's employer, Joseph Miller, tried to win her back in Baltimore, he was murdered. The outrage drove Pennsylvania officials to fight for the sisters in a Maryland court, which finally secured their freedom in 1853.

Parker's Landing Petroglyphs

Perry Township, PA

For countless generations, Native people came to the rocks along the Allegheny River near here to carve images of humans, animals, mythical beings, and abstract shapes. The number and variety of these petroglyphs, set against an undeveloped landscape, make the site remarkable. Now submerged for most of the year, the carvings preserve the legends and beliefs of people who lived and traveled through Pennsylvania thousands of years ago.

Patrick C. Boyle (1846-1920)

Oil City, PA · est. 2013

In the decades after the 1859 Drake Well strike, northwestern Pennsylvania's Oil Region became the crucible of the world's first petroleum boom, and Oil City sat at its heart. Patrick C. Boyle rose from the rough-and-tumble world of the oil scout to build trade papers—The Derrick and The Oil and Gas Journal—that told drillers, refiners, and investors what was happening across the fields. His publications gave a chaotic new industry a shared language and a national nervous system of prices and news.
