Historic Markers in Pennsylvania

Philadelphia, PA · est. 1988

Born in Maryland in 1779, Stephen Decatur spent his boyhood in a house that once stood on this Philadelphia site before rising to become one of the young U.S. Navy's most celebrated officers. He made his name in the Tripolitan War of 1804, captured HMS Macedonian in 1812, and helped bring the Barbary powers to heel in 1815. His bold career ended in 1820 when he was killed in a duel and laid to rest at St. Peter's Church.

Athens, PA · est. 1947

Before he became the father of American popular song, a teenaged Stephen Foster passed through the Susquehanna country of northern Pennsylvania. In 1840-41 he attended Athens Academy, a small classical school that once stood on this ground, and it was here that he composed his very first piece of music, the "Tioga Waltz." The tune reportedly grew out of a school exhibition, an early flash of the melodic gift that would soon give America "Oh! Susanna" and "Camptown Races."

Towanda, PA · est. 1947

In 1840-41 the young Stephen Foster lived in Towanda, staying with his older brother William, an official on the canal system then knitting the Pennsylvania interior to distant markets. He briefly attended the academy on the hill above town during a restless boyhood that carried him among several schools. These northern Pennsylvania years came just before Foster began publishing the folk songs and parlor ballads that made him famous.

Philadelphia, PA · est. 1993

Stephen Girard arrived in Philadelphia in 1776, just as the young republic was being born, and rose to become one of America's wealthiest merchants and financiers. His backing steadied the First and Second Banks of the United States during the nation's precarious early decades, and his fortune later funded Girard College, which opened in 1848 to educate orphaned boys. This site held Gentilhommiere, his country house and a working farm of nearly 600 acres.

Philadelphia, PA · est. 1991

Born enslaved in 1795, Stephen Smith purchased his own freedom and went on to become one of the wealthiest African Americans of his era, amassing a fortune in coal, lumber, and real estate. He poured his means and influence into the abolitionist cause and philanthropy, most notably as the principal benefactor of the Stephen Smith Home for the Aged, which stood on this site. His life bridged the worlds of business, activism, and charity in the decades surrounding the Civil War.

Fountain Hill, PA

In a house on this Fountain Hill hillside in 1898, the writer Stephen Vincent Benét was born into a literary family that would produce several published authors. He grew up steeped in books and history, and by the 1920s and '30s had become one of America's most celebrated poets and storytellers. His verse epic of the Civil War, "John Brown's Body," won wide acclaim for the way it wove ordinary soldiers, statesmen, and everyday Americans into a sweeping national portrait. He died in 1943, still in his prime, having spent his final years urging his countrymen to hold fast to their founding ideals.

Stewartstown, PA

The Stewartstown Railroad was chartered in 1884, during the Gilded Age boom when short-line railroads stitched small Pennsylvania towns into the national network of commerce. Running just a few miles from Stewartstown to a connection near New Freedom, it carried freight and passengers and linked the community outward to Baltimore, Harrisburg, and York. The handsome station built here in 1914 anchored the town's Main Street to that wider world, moving farm goods to market and travelers to the cities beyond.

Manheim, PA · est. 1962

On this site the flamboyant ironmaster and entrepreneur Henry William Stiegel — who styled himself "Baron" — built a glassworks that operated from 1763 to 1774. His tableware and decorative glass were among the finest produced in colonial America, prized then and treasured by collectors ever since. The original building stood until 1813, long after Stiegel's overreaching ventures collapsed into debt.

McKees Rocks, PA

In 1976 the United States marked its 200th birthday, and communities across the country threw parades, buried time capsules, and raised markers to the occasion. The Sto-Rox Bicentennial Committee — named for the twin boroughs of Stowe Township and McKees Rocks along the Ohio River west of Pittsburgh — left this monument as a message across a full century, addressed from the people of 1976 to the people of 2076. It captures a moment when a hard-working industrial river town paused to place itself in the long arc of the American story.

Silver Spring Township, PA · est. 2017

At James Bell's tavern on this ground, Anti-Federalists from the Cumberland frontier gathered in 1788 under the leadership of Robert Whitehill to voice their opposition to the newly drafted U.S. Constitution. They objected that it lacked protections for individual liberties and the rights of the states, and they pressed for amendments. Their demands are tied to the eventual adoption of the Bill of Rights and to the rise of the Democratic-Republican Party.

Honesdale, PA · est. 1947

On August 8, 1829, at Honesdale, the Stourbridge Lion made the first run of a steam locomotive on rails in the United States. English-built for the level stretches of the Delaware & Hudson's gravity railroad, the engine was piloted by Horatio Allen, who took it out despite doubts that the wooden trestlework could bear its weight. The trial proved that steam power could move on iron rails on American soil — a glimpse of the railroad age to come.

Honesdale, PA · est. 1947

Honesdale honors its place in railroad history with a replica of the Stourbridge Lion, the English-built engine that in 1829 became the first locomotive to run on rails in the United States. Displayed beside it is the Eclipse, an original passenger coach from the Delaware & Hudson's gravity railroad. Together they recall the town's role at the very dawn of American railroading.

Strasburg Township, PA · est. 2011

Chartered in 1832 after the state's main line bypassed the town, the Strasburg Rail Road refused to fade away — it is the oldest American railroad still running under its original charter. Rescued from abandonment by local enthusiasts in 1958, it was reborn as one of the country's most beloved tourist lines. Its fleet of working steam locomotives and vintage cars, among the largest anywhere, keeps Pennsylvania's rail heritage alive and in motion.

Philadelphia, PA

This marker recalls two grand Philadelphia buildings that once stood on this ground before fire swept them away. The Harrison Stratton Mansion belonged to the era when the city's prosperous families raised stately residences reflecting the wealth of a booming industrial metropolis, while the Sunderland was one of the early apartment buildings that reshaped how urban Americans lived as cities densified around the turn of the twentieth century. Their loss to fire was a common fate in an age when timber framing, coal heat, and open flame made conflagration a constant threat to city blocks.

Berwick, PA · est. 2015

During World War II, more than nine thousand workers at Berwick's American Car & Foundry plant built over 15,000 Stuart tanks for American and Allied forces. Light, fast, and nimble, the Stuart was the first U.S. tank produced on a moving assembly line and saw combat on battlefronts around the globe. A.C.F. grew into the nation's largest maker of armor plate, with its own ballistics testing range.

East Berlin, PA · est. 1970

Built around 1790 by David Studebaker—a carpenter, farmer, and minister—this early Pennsylvania home stands connected to one of America's great manufacturing dynasties. The Studebaker family to which he was related would go on to build the wagons that carried settlers west and, later, automobiles. Today the house is privately kept as a museum.

Chambersburg, PA · est. 1969

This Federal-era house, built around 1807, later served as the home of Dr. Jacob Suesserott, a well-regarded physician and surgeon. Its place in history was sealed on July 30, 1864, when Confederate cavalry under orders to extract a ransom set fire to Chambersburg; the flames that consumed much of the town were halted at this point. The burning of Chambersburg remains the only major Northern town destroyed by Confederate forces during the Civil War.

Sugarloaf Township, PA · est. 1947

In the autumn of 1780 a party of Native warriors and Loyalist Tories, turned back from an attempt on Fort Augusta, fell upon a detachment of Northumberland County militia near here. The surprise attack on September 11 left the small company overwhelmed, one of many such bloody clashes that made the Pennsylvania frontier a war zone long after the fighting had shifted elsewhere.

Conyngham, PA · est. 1933

In September 1780, as the Revolutionary War flared along the Pennsylvania frontier, a detachment of Northampton County militia paused to rest at a spring near Sugarloaf Mountain. They were ambushed by a party of Native warriors and Loyalists led by the Seneca chief Roland Montour, and more than a dozen men were killed. The marker preserves the names of the fallen, a roster of ordinary frontier soldiers caught in the war's brutal borderland fighting.

Forks Township, PA · est. 1947

In the summer of 1779, Easton became the staging ground for one of the Revolution's largest offensives against the Native and Loyalist alliance harrying the New York and Pennsylvania frontier. Under General John Sullivan, the army spent more than a month gathering men and supplies before beginning its march on June 18, 1779. The campaign that followed would drive deep into Iroquois country to the north.

Laporte, PA · est. 1982

Sullivan County was created in 1847 out of Lycoming County, taking its name from state senator Charles C. Sullivan, who pushed for its formation. Laporte became the county seat in 1853. In the wooded highlands here, Eagles Mere grew into a celebrated mountain resort and Worlds End became a beloved state park.

Wilkes-Barre, PA · est. 1929

In the summer of 1779 the Wyoming Valley became the assembly point for General John Sullivan's expedition against the Iroquois. From late June through the end of July, the army gathered, drilled, and stockpiled supplies at its mobilization camp here before marching north up the Susquehanna. This staging at Fort Wyoming set in motion one of the Revolution's largest offensive campaigns.

Wind Gap, PA · est. 1929

On June 18, 1779, Sullivan's troops set out on the first day of their long march toward Iroquois country, covering twelve miles before halting at Heller's Tavern. Wayside taverns like this were the natural waypoints of the era, offering the only fixed shelter along frontier roads. The plaque marks where the campaign's opening day came to a close.

Sheshequin Township, PA · est. 1929

In August 1779 General John Sullivan marched his Continental army up the Susquehanna Valley on a campaign to break the power of the Iroquois Confederacy, which had raided frontier settlements as Britain's allies. On the night of August 10 the army made its seventh and final encampment before reaching Teaoga on these river lowlands at Sheshecunnunck. The march was one leg of a systematic expedition that would destroy dozens of Iroquois towns and cornfields.

Forks Township, PA · est. 1929

This plaque marks the road over which Sullivan's army began its advance on June 18, 1779. Cutting and following such roads was itself a feat, as thousands of men, horses, and wagons of supplies moved through country with few improved routes. The path set the direction of a campaign that would carry deep into the lands of the Six Nations.

Athens, PA · est. 1929

Teaoga was a key Iroquois village at the forks of the rivers, and in August 1779 it became the staging ground for General John Sullivan's army during its campaign against the Six Nations. From roughly August 11 to 26 the Continental force encamped near here before pressing deeper into Iroquois country. This marker fixes the village's site relative to that fateful summer of the Sullivan Expedition.

Tunkhannock, PA · est. 1929

In the summer of 1779, at the height of the American Revolution, General John Sullivan led a punishing campaign up the Susquehanna Valley against the Iroquois nations allied with the British. This plaque marks a waypoint on that march from Wyoming to Teaoga, where on August 3 the army camped on the lowlands between here and the river. The relentless expedition burned Iroquois towns and crops, breaking the military power of the Six Nations in the region.

Meshoppen Township, PA · est. 1929

As General Sullivan's army pushed north against the Iroquois in August 1779, it made its fourth encampment on the fertile bottomland here, remembered locally as Black Walnut Flats. The soldiers rested on the nights of August 4 and 5 before continuing the march from Wyoming toward Teaoga. The campaign systematically destroyed the towns and food stores of the Six Nations across this valley.

Wyalusing Township, PA · est. 1929

Wyalusing had been the site of Friedenshütten, a Moravian mission town where Christian Delaware Indians lived before being pushed westward in the early 1770s. A few years later, in August 1779, General Sullivan's army made its fifth encampment here on the march from Wyoming toward Teaoga. The marker stands near the monument to that vanished Moravian Indian community.

Stroudsburg, PA · est. 1929

In the spring of 1779, General George Washington ordered a punishing campaign into the heart of Iroquois country to end frontier raids allied with the British. Here at Fort Penn, the fortified home of Col. Jacob Stroud served as a rendezvous where companies gathered before joining the main army. From this staging ground in the Pocono foothills, men and supplies funneled westward toward the march that would follow.

Pocono Township, PA · est. 1929

As Sullivan's army pushed into the wilderness in June 1779, it left the settled country behind. This spot, remembered as "the last house on the frontier," marked the end of the second day's march — a sixteen-mile push into thinning settlement. Beyond here lay forest and the long road to Iroquois territory.

Pocono Township, PA · est. 1929

On June 20, 1779, the third day's march ended at a spot the soldiers dubbed Chowder Camp, where General Sullivan is remembered as dining on trout chowder pulled from the mountain streams. The short five-mile advance hints at the rough terrain slowing an army hauling artillery and supplies into the Poconos. Small human details like a general's stream-caught supper survive alongside the grand campaign.

Philadelphia, PA · est. 2016

Opened in 1968, Sullivan Progress Plaza was the first shopping center in the nation built, owned, and operated by African Americans. It grew from the efforts of Rev. Leon H. Sullivan, members of Zion Baptist Church, and the surrounding Black community, who pooled small investments to create it. Its visible success drew national notice—prompting President Nixon to fund a corporation to spread similar commercial development—and inspired Black-led economic ventures across the country.

Wyalusing Township, PA · est. 1947

In the summer of 1779, at the height of the Revolution, General John Sullivan led a Continental army up the Susquehanna Valley, camping near here on August 5-7 as it pushed north. The expedition, ordered by George Washington, aimed to break the power of the Iroquois nations allied with the British and to end the devastating raids along the frontier. Over the campaign Sullivan's troops burned dozens of Haudenosaunee towns and their harvests.

Standing Stone Township, PA · est. 1947

As General John Sullivan's Continental army marched north against the Six Nations in August 1779, it made its sixth camp on the river lowlands near here on the nights of August 8-9. The stopping places along the Susquehanna traced the slow, deliberate advance of a major Revolutionary War expedition ordered by Washington. From Wyoming to Fort Sullivan, each riverside campsite marked another day's push into Iroquois country.

Hamilton Township, PA · est. 1947

Brinker's Mill served as the storehouse and forward supply post for the Sullivan Expedition, the 1779 Continental Army campaign that marched out of Easton on June 18 to strike the Iroquois nations allied with Britain. Ordered by George Washington in response to frontier raids, the expedition aimed to break Iroquois power in the region. This mill helped provision an army bound for one of the Revolution's harshest campaigns.

Pocono Township, PA · est. 1947

On June 19, 1779, the army of the Sullivan Expedition camped near Learned's Tavern at the close of its second day out of Easton, having covered sixteen miles from Heller's Tavern on the long road toward Fort Wyoming at Wilkes-Barre. The tavern marked a waypoint on the campaign George Washington launched against the British-allied Iroquois. These recorded halts trace the grueling overland route of one of the Revolution's most consequential frontier operations.

Wind Gap, PA · est. 1947

On June 18, 1779, the first day's march of General Sullivan's expedition ended at Heller's Tavern near Wind Gap, where his weary army camped for the night. Stirring at four the next morning, the troops pressed on to cross the Blue Mountains through the natural pass at Wind Gap. Their route traced old paths through the ridges as they moved north toward the Iroquois heartland.

Tunkhannock, PA · est. 1947

In the summer of 1779, General John Sullivan led thousands of Continental soldiers up the Susquehanna Valley in a scorched-earth campaign ordered by George Washington against the Iroquois Confederacy, allies of the British. On August 3, that army made its third camp above Fort Wyoming here by the river as it pushed north toward Tioga. The march devastated Iroquois towns and croplands, breaking the power of the Six Nations on the New York–Pennsylvania frontier.

Exeter Township, PA · est. 1947

During the Revolution's Sullivan Expedition of 1779, General John Sullivan's Continental army moved north up the Susquehanna from Fort Wyoming at Wilkes-Barre toward Tioga. On August 1–2 the troops encamped on the lowland across the river here — the second stop on a grueling march through frontier country. The campaign was Washington's answer to raids on the frontier, aimed at the Iroquois Confederacy allied with the British.

Meshoppen Township, PA · est. 1947

On August 4, 1779, General John Sullivan's Continental army made its fourth encampment on the lowland here as it marched from Fort Wyoming toward Tioga Point. The column was part of a coordinated Revolutionary War campaign against the Iroquois Confederacy, whose warriors had raided settlements along the frontier. The soldiers' northward advance up the Susquehanna would culminate in the destruction of dozens of Native towns.

Ulster Township, PA · est. 1949

In August 1779, General John Sullivan led a Continental Army expedition up the Susquehanna Valley, camping on the Sheshequin Flats below this point on the ninth and tenth before pressing on to Tioga Point. This was the seventh and final overnight stop of a hard march into Iroquois country. Sullivan's campaign, ordered by George Washington, aimed to break the power of the Six Nations who had allied with the British on the frontier.

Morrisville, PA · est. 1949

Built in 1773 by Thomas Barkley, this fine house near Morrisville briefly sheltered George Washington and his army from December 8 to 14, 1776, in the desperate weeks before the crossing of the Delaware. Its later owners included Robert Morris, financier of the Revolution, and George Clymer, a signer of the Declaration of Independence. The house was restored in 1931.

Bethlehem, PA · est. 1953

Begun in 1758, the Sun Inn quickly earned a reputation as one of the finest hostelries in the colonies, and during the Revolutionary War it welcomed a remarkable roster of patriots and military leaders passing through Bethlehem. Travelers found comfortable lodging and good food at a time when such quality was rare on American roads. The inn's guest list reads like a directory of the Revolutionary generation, making it a crossroads of the era's political and military life.

Chester, PA · est. 2007

Founded by the Pew family in 1916 along the Delaware River, Sun Shipbuilding and Dry Dock Company grew during World War II into the largest single shipyard on earth, employing more than 35,000 workers. Sun pioneered the all-welded ship and the T-2 oil tanker that became the standard across American yards, building over 250 wartime tankers—roughly 40 percent of the world's total—and repairing more than 1,500 damaged vessels. The yard operated on this Chester waterfront until 1982.

Sunbury, PA · est. 1947

Laid out in 1772 as the seat of newly formed Northumberland County, Sunbury rose on the site of Shamokin, a major Native town at the forks of the Susquehanna. Surveyors John Lukens and William Maclay platted the town where Fort Augusta had stood since 1756, guarding the frontier, and the community grew into a hub of travel, trade, and industry before its incorporation as a borough in 1797.

Shamokin Dam, PA · est. 1948

Sunbury was laid out in 1772 as the seat of newly formed Northumberland County, planted on the site of Shamokin, an important Native American town at the forks of the Susquehanna. Sixteen years earlier, during the French and Indian War, colonial authorities had built Fort Augusta here to guard the frontier. The spot's command of the river made it a lasting hub of travel, trade, and industry.

Penn Township, PA · est. 2018

From 1940 to 1995 the Waltman family ran Sunset Park, a Chester County stage that grew into one of the premier country and bluegrass venues outside Nashville. Over its decades it hosted the giants of the genre — Hank Williams, Loretta Lynn, Dolly Parton, Randy Travis, and bluegrass founder Bill Monroe among them. The park helped carry American roots music through its transformation from pre-war "hillbilly" sound into the nationally beloved country genre, and preserved live recordings of many of those performances.

Philadelphia, PA · est. 2026

Traced to legislation passed by Pennsylvania's colonial assembly in 1684, the Supreme Court of Pennsylvania stands as the oldest appellate court in the nation. Over the centuries it handed down influential rulings touching the abolition of slavery, the rights of labor, and the rights of women. Its structure and reasoning became a model that federal and other state courts would follow.

Wrightsville, PA · est. 1948

Chartered by Pennsylvania in 1835, the Susquehanna and Tidewater Canal ran for forty-five miles along the river below Columbia, carrying coal, lumber, and produce toward Chesapeake tidewater. The canal company operated the waterway from 1840 until 1872, after which the Reading Railroad ran it until 1894, when rail had all but eclipsed the towpath. This stretch at Wrightsville stood near the canal's northern reaches along the lower Susquehanna.

Lower Chanceford Township, PA · est. 1948

Chartered by Pennsylvania in 1835, the Susquehanna and Tidewater Canal followed the river for forty-five miles below Columbia, moving freight between the Pennsylvania interior and Chesapeake tidewater. Run by the canal company from 1840 to 1872 and then by the Reading Railroad until 1894, it embodied a transportation technology already being surpassed by the iron horse. This marker in Lower Chanceford Township traces the canal's southward course toward Maryland.

Lower Windsor Township, PA · est. 1948

The Susquehanna and Tidewater Canal, chartered by Pennsylvania in 1835, carried coal and goods forty-five miles along the river below Columbia toward the Chesapeake. Operated by the canal company from 1840 to 1872 and afterward by the Reading Railroad until 1894, it served the valley through the middle decades of the nineteenth century before rail transport prevailed. This marker in Lower Windsor Township lies along the old route beside the lower Susquehanna.

Lower Windsor Township, PA · est. 1948

In the canal-building decades of the early 1800s, engineers threaded slackwater channels alongside the rocky lower Susquehanna, where the river itself was too swift and shallow to boat. The stone lockwork surviving beside the water here belonged to that system, floating coal, grain, lumber, and iron down from Columbia toward tidewater and the markets of Baltimore. Each mortared lock stepped loaded boats down the valley's fall, a quiet piece of engineering that once hummed with mule teams and boat traffic.

Wrightsville, PA · est. 1948

At Wrightsville the towpath canal reached its northern end and joined the state's own canal works across the river at Columbia, making this a busy transfer point in the mid-19th century. The inscription preserves a vivid detail of how goods crossed the wide Susquehanna: mules once towed boats over a towpath built onto the river bridge, and after 1863 tugboats hauled the canal craft across instead. It was a working seam between two arteries of a growing trade network.

Lower Chanceford Township, PA · est. 1948

The stone building near this marker, later home to the Tucquan Club, began life as a canal warehouse where cargo was deposited and loaded for shipment along the Susquehanna. Traces of the old canal bed and scattered masonry still mark where boats once tied up to take on goods. Such warehouses were the loading docks of their age, the points where a farm's harvest or a mill's output entered the long float to market.

Montrose, PA · est. 1982

Split from Luzerne County in 1810 and named for its great river, Susquehanna County became an early hotbed of antislavery activity, with Montrose serving as an Underground Railroad stop. It was also home to Galusha A. Grow, the congressman who championed the 1862 Homestead Act. That law opened millions of acres of western land to ordinary settlers.

South Williamsport, PA · est. 1962

Beginning with a company incorporated in 1846, a six-mile line of cribbed piers was strung across the West Branch of the Susquehanna to catch and hold the timber floated down during the spring log drives. This boom fed the sawmills that made Williamsport, for a time, the lumber capital of the world. A devastating flood in 1889 broke the boom, and it declined as the great pineries were cut out.

Selinsgrove, PA · est. 1948

Founded in 1858 by the Evangelical Lutheran Church, the school began as a pairing of the Missionary Institute with the Susquehanna Female College—an unusual early commitment to educating women alongside training clergy. It grew steadily through the nineteenth century and took its present name, Susquehanna University, in 1895. It remains a fixture of Selinsgrove.

Lemoyne, PA · est. 2021

Excavations near Lemoyne in the early 2000s revealed a palisaded Susquehannock village from the early 1600s, its ground scattered with iron, brass, and glass trade beads. Those artifacts trace early contact with Dutch traders and the fledgling English colony at Jamestown between 1610 and 1624, when goods moved along Native networks long before Europeans settled the region. The findings deepened understanding of how the Susquehannock organized their villages and their world on the eve of sustained colonial pressure.

Union Township, PA · est. 1947

Swatara Gap is a natural break in the Blue Mountain, and in the 1750s it became a dangerous doorway. During the French and Indian War, war parties allied with the French slipped through the gap to strike the scattered farms of the Pennsylvania frontier, and colonial authorities answered by raising Fort Swatara nearby to guard the pass. The steep, wooded notch that had long served as a travel route became a frontline in a brutal borderland conflict.
