Historic Markers in Pennsylvania

Leechburg, PA · est. 2017

Built between 1826 and 1834, the state-owned Pennsylvania Canal was an ambitious bid to knit Philadelphia, Pittsburgh, and Erie together by water. This 104-mile Western Division ran from Johnstown to Pittsburgh, and Dam #1, raised at Leechburg in 1827, fed the route and created seven miles of slackwater navigation toward Apollo. The dam served until 1865 and was finally swept away in the catastrophic Johnstown Flood of 1889.

Harrisburg, PA · est. 1991

First held in January 1917, the Pennsylvania Farm Show began as a modest winter gathering that rotated among Harrisburg venues before settling into a purpose-built Main Exhibition Building in 1931. The addition of the Large Arena for the 1939 show cemented its permanent home in the state capital. Over the decades it swelled into one of the largest indoor agricultural expositions on earth, a January fixture where farmers, breeders, and butter-sculptors converge.

Susquehanna Township, PA · est. 2016

Just after the Civil War, Pennsylvania's rivers were being fouled by industrial pollution and blocked by dams that cut off the migrating fish that once filled them. In 1866 Governor Andrew Curtin signed a law creating a state commission to restore those waters and fisheries, among the earliest such bodies in the nation. From hatcheries to habitat protection and law enforcement, the agency grew into a model that other states and federal programs would follow.

Franklin Township, PA · est. 1947

Established around 1810, Pennsylvania Furnace was one of the many iron works that flourished along the streams of the Juniata region in the early 19th century. It began by smelting ore with charcoal from the surrounding forests, then adapted to coke as fuel technology changed, keeping iron flowing here as late as 1888. The surviving buildings offer a tangible link to nearly a century of ironmaking.

Dunmore, PA · est. 1999

From 1850 to 1884 the Pennsylvania Coal Company operated a gravity railroad between lower Pittston and Hawley, moving anthracite across the rugged coal country of northeastern Pennsylvania. Near this point the line crossed the highway on an overhead trestle at what was designated Plane No. 7 — one of the inclined planes that let gravity and stationary engines move loaded cars over the hills. It was part of a vast network built to carry coal out of the region.

Philadelphia, PA · est. 1992

Built in 1838 by the Pennsylvania Anti-Slavery Society, Pennsylvania Hall was meant to be a grand meeting place where abolitionists could gather freely in a city long divided over slavery. Just three days after its opening, an anti-Black mob set the building ablaze and burned it to the ground while authorities stood by. The attack laid bare the fierce hostility abolitionists faced even in the North.

Philadelphia, PA · est. 1954

Chartered by the Colonial Assembly in 1751 for the "relief of the sick poor," Pennsylvania Hospital was the first hospital in what would become the United States. Benjamin Franklin and Dr. Thomas Bond led its founding, and the original building of 1755 remains in use to this day. It set a model of organized, charitable medical care that had never before existed in the colonies.

Bellefonte, PA · est. 2004

Founded in 1899 by local entrepreneurs, the Pennsylvania Match Factory opened its doors in 1900 to tap the immense timber of central Pennsylvania's lumber country. For the first half of the 20th century it ranked among the nation's leading makers of wooden matches, and by World War II its workforce had swelled to 400 under the Universal Match Corporation. Book matches and cigarette lighters finally undercut it, and the plant closed in 1947.

Lancaster, PA · est. 1998

In 1848, physicians gathered in a Lancaster church to organize the Pennsylvania Medical Society, part of a broader mid-century push to put American medicine on a professional footing. At a time when training and standards varied wildly, the society aimed to advance medical knowledge, ease suffering, and improve public health. Local doctor Samuel Humes served as its first president.

Brookville, PA · est. 2019

A generation after the Civil War, the men who had served the Union were aging, and their families often had nowhere to turn. In 1890 Kate Scott and Annie Wittenmyer of the Woman's Relief Corps founded a home in Brookville that broke new ground: it took in not only veterans but also their wives, children, widows, and orphans. It is remembered as the first such home in the nation to care for whole families.

Erie, PA · est. 2015

The 112th Infantry Regiment traces its lineage to the 83rd Pennsylvania Volunteer Infantry, raised in Erie in 1861 as the Civil War began. Reorganized over the decades, it became part of the 28th Division, the oldest continuously serving infantry division in the U.S. Army, and its soldiers fought in the Spanish-American War, both World Wars, Korea, and Iraq. For ninety years those units mustered at the Erie Armory, a building now listed on the National Register of Historic Places.

Altoona, PA · est. 1996

In 1850 the Pennsylvania Railroad laid its first track to Altoona and built its first repair shops there, and the town grew up around the industry. Nestled at the foot of the Allegheny grade, Altoona became the beating mechanical heart of the mightiest railroad in America. By 1925 it held the nation's largest concentration of railroad shops, where some 16,500 workers built and mended the locomotives and cars that moved the country.

Lancaster Township, PA · est. 1947

The long, slender flintlock famous as the "Kentucky Rifle" was in truth a Pennsylvania creation, refined by German-American gunsmiths around Lancaster during the 1700s. Accurate at ranges that stunned European soldiers, it became the tool of the frontier hunter and, later, a weapon of legend in the Revolution — a piece of American craftsmanship carried far beyond the state that perfected it.

Harrisburg, PA · est. 2003

Founded in 1903 as a division of the State Library, the Pennsylvania State Archives gathered up the paper memory of a commonwealth whose records reach back to 1681 and William Penn's founding charter. In 1945 it joined the newly created Historical and Museum Commission, cementing its role as guardian of the state's documentary past. Its shelves preserve the raw material from which Pennsylvania's history is written.

Mont Alto, PA · est. 2003

When conservation was still a new idea in America, Pennsylvania opened its first forestry school here at Mont Alto in 1903, formally named the State Forest Academy two years later. Its founders included Joseph Rothrock, the state's first Forestry Commissioner, and the activist Mira Lloyd Dock, both leaders in the movement to reclaim lands stripped bare by logging. In 1929 the academy merged into what became Pennsylvania State University.

Derry Township, PA · est. 2005

Created by an act signed by Governor Samuel Pennypacker on May 2, 1905, the Pennsylvania State Police was the first uniformed state police force of its kind in the nation. It grew out of alarm over labor and capital conflict — above all the great Anthracite Coal Strike of 1902 — and set a template other states would copy. In 1924 the force opened its first training academy at this site, where cadets drilled for 36 years before a new academy was built north of Hershey.

Bedford Township, PA · est. 1990

When the Pennsylvania Turnpike opened on October 1, 1940, running 160 miles from Irwin to Carlisle, drivers experienced something America had never seen: a long-distance, limited-access superhighway with no cross traffic and no stoplights. Engineers routed it along the abandoned grade and tunnels of the never-finished South Pennsylvania Railroad, and service plazas like this one let travelers fuel up and rest without leaving the road. By 1957 the turnpike stretched 360 miles across the state with a spur reaching toward Scranton.

Bedford Township, PA · est. 1990

The Pennsylvania Turnpike opened on October 1, 1940, a 160-mile run from Irwin to Carlisle that introduced Americans to the limited-access superhighway. Built along the right-of-way and tunnels of the unfinished South Pennsylvania Railroad and overseen by a commission created in 1937, it dispensed with intersections and traffic signals entirely. Service plazas such as this one kept motorists moving, and by 1957 the road reached 360 miles across the state with a 110-mile extension toward Scranton.

Philadelphia, PA · est. 2012

Built about 1697 where a Lenape trail forded Pennypack Creek, this modest triple-arched stone span is reckoned the oldest roadway bridge in continuous use in the United States. It carried the King's Highway, one of colonial America's great overland routes, and in 1781 bore the tramp of American and French troops marching south with Rochambeau toward the decisive siege of Yorktown. Widened only once, in 1893, its upstream face looks much as it did when William Penn's colony was young.

Perkiomen Township, PA · est. 1946

This Montgomery County house served as George Washington's headquarters in the autumn of 1777, during the fraught campaign around Philadelphia in the Revolutionary War. Generations later it became the beloved home of Samuel W. Pennypacker, who served as governor of Pennsylvania in the early 1900s and died here in 1916. Few homes can claim to have sheltered both a founding general and a modern governor beneath one roof.

Grove Township, PA · est. 2016

During the Great Depression, the Civilian Conservation Corps put young men to work on America's forests and public lands, including fighting wildfires across Pennsylvania's mountainous north. In 1938 a crew of teenage enrollees and their foreman, already worn down from an earlier blaze, were overtaken while battling a fire on these ridges. The loss became a lasting lesson: decades later, wildland fire trainers still study what happened here to keep crews alive.

Lower Providence Township, PA · est. 1947

Completed in 1799, this stone-arch span across the Perkiomen Creek ranks among the oldest bridges still carrying traffic in Pennsylvania. Its construction was financed in a distinctly early-American way: a state-authorized lottery, sanctioned by an act of 1797, that raised $20,000 for the work. In an age before public infrastructure budgets, lotteries and subscriptions were how a young republic paid to knit its roads together.

Bloomfield, PA · est. 1982

Perry County was set off from Cumberland County in 1820 and named in honor of Oliver Hazard Perry, the naval hero whose victory on Lake Erie became one of the proudest moments of the War of 1812. This rural county along the Juniata proved a fertile ground for public men, sending sons on to serve as governors of Pennsylvania and of three other states. Its seat, Bloomfield, was incorporated in 1831.

Marysville, PA

This memorial wall honors the sons and daughters of Perry County who served in uniform, and especially those who gave their lives in that service. Rural Pennsylvania counties like Perry sent generations of young people to the nation's wars, and communities gathered to inscribe their names so they would not be forgotten. The wall draws that shared sacrifice into one place of remembrance.

Erie, PA · est. 1946

In the spring of 1813, with the War of 1812 raging on the Great Lakes, American shipwrights raced to build a fleet at the foot of this street in Erie. The vessels launched here — among them the Lawrence, the Niagara, and the Ariel — carried Oliver Hazard Perry to his famous victory at the Battle of Lake Erie that September. Warehouses, a blockhouse, and a lookout once clustered along this shore to guard and supply the yard.

Nanticoke, PA · est. 2003

Pete Gray grew up in the coal town of Nanticoke, where a boyhood accident cost him his right arm — yet he taught himself to bat, field, and quickly transfer the ball from glove to bare hand. Named MVP of the Southern Association with the Memphis Chicks in 1944, he reached the majors the next year, playing 77 games in the outfield for the wartime St. Louis Browns. His single big-league season made him one of baseball's most improbable and inspiring figures.

Coatesville, PA · est. 1954

Peter Bezellon was a noted Indian trader and interpreter in colonial Pennsylvania who bought a 500-acre tract in this area in 1736, part of which includes this site. Traders like Bezellon lived at the meeting point of two worlds, moving goods and words between colonial settlers and Native nations in the decades of early contact along the frontier. He died in 1742 and lies buried with his wife, Martha, in St. John's churchyard at Compass.

Nescopeck, PA · est. 1970

Born in Nescopeck on July 8, 1812, Peter F. Rothermel rose to become one of nineteenth-century Pennsylvania's most celebrated painters. His monumental canvas of the Battle of Gettysburg, commissioned by the State Legislature, remains among the most ambitious American history paintings of its era. The marker honors the small river town that produced an artist whose brush helped shape how a generation pictured the Civil War's defining battle.

Elizabeth Township, PA

In the wooded hills of Lancaster County, ironmaster Peter Grubb raised this forge in 1742, part of the network of charcoal-fired "iron plantations" that made colonial Pennsylvania one of the largest iron producers in the British Empire. At an upper forge like this one, workers refined brittle pig iron under water-powered hammers into tough, malleable wrought iron — the bar stock a young country needed for tools, hardware, and horseshoes. The Grubb family's ironworks grew into one of the region's great iron dynasties, and this forge kept its hammers ringing until 1803, through the Revolution and into the early Republic. Long after the fires went cold, the ground was set aside as a wildlife sanctuary and place of rest in memory of Richard "Dick" Eugene Connelly.

Williamsport, PA · est. 1996

Peter Herdic was a driving force behind Williamsport's rise as the self-proclaimed "lumber capital of the world." As a mill owner and president of the Susquehanna Boom — the great log-catching works on the river — he helped turn the city's timber wealth into the mansions of "Millionaire's Row," many of which he built. An inventor as well, he patented the "herdic," a low, rear-entry public carriage, and made his own home at No. 407.

Philadelphia, PA · est. 1982

William Penn laid out Philadelphia in 1682 on a rational grid between two rivers, envisioning a 'greene countrie towne' whose very name proclaimed brotherly love. Chartered as a city in 1701, it served as Pennsylvania's capital until 1799 and, during the founding era, as the capital of the United States until the government moved to Washington in 1800. The surrounding county, one of Pennsylvania's original three, was consolidated with the city in 1854.

Philadelphia, PA · est. 2001

Authorized by the Pennsylvania legislature in 1828 and completed in 1834, the Philadelphia & Columbia Railroad was among the earliest railroads in America, running 82 miles west to the Susquehanna River. Its cars were first pulled by horses and later by steam locomotives, and it formed part of a state-owned network—including the Pennsylvania canal—built to keep the commonwealth competitive with rival states scrambling for western trade. The Pennsylvania Railroad absorbed the line in 1857, and stone blocks laid for the original track can still be seen here.

Caln Township, PA · est. 1999

Chartered by the state legislature in 1792 and completed two years later, the Philadelphia & Lancaster Turnpike was the nation's first major toll road — a 62-mile stone-and-gravel highway hailed as the finest of its day. Built by a private company, it inspired a wave of turnpike-building that knit the young republic together. The 35th milestone from Philadelphia stood here, and the route later became part of the Lincoln Highway and U.S. 30.

Philadelphia, PA · est. 2010

Philadelphia's Chinatown took root in the 1870s as Chinese immigrants opened businesses and made homes in this district, building a community that sustained Chinese American life for generations. Through decades of exclusion laws and hardship, the neighborhood preserved Asian cultural traditions and a distinct ethnic identity. By the 1920s it stood as the only remaining Chinatown in Pennsylvania.

Philadelphia, PA · est. 1971

In 1821, a group of Philadelphia apothecaries gathered at historic Carpenters' Hall—the same building where the First Continental Congress had met—to found a college that would raise pharmacy from an informal trade into a trained profession. Incorporated the following year, it became the first pharmacy school in the United States. Its founding reflected the young republic's broad push to professionalize the sciences and safeguard public health.

Philadelphia, PA · est. 1969

Founded in 1884 as the Philadelphia Textile School, this was the first institution in America devoted to training workers for the textile industry. In an era when Philadelphia was a powerhouse of American manufacturing, the school aimed to lift the quality and competitiveness of domestic fabrics through technical education. It grew over the following century into a full college on this campus.

Philadelphia, PA · est. 1992

In 1833, Quaker reformer Lucretia Mott helped organize this society of some sixty women dedicated to ending slavery, headquartered on this spot. Barred from full participation in male-led abolition groups, these women built their own influential organization, raising funds and rallying support for emancipation. After the Civil War, they turned their energies to aiding the newly freed, extending their reform work into a new era.

Philadelphia, PA · est. 2019

In 1829 the Pennsylvania Horticultural Society staged its first flower show here, launching what would become the nation's largest and longest-running horticultural event. It was on this stage that American audiences first met now-familiar plants like the poinsettia and the chrysanthemum. Nearly two centuries on, the show remains a fixture among the world's great garden exhibitions.

Philadelphia, PA · est. 2021

Founded on this site in 1976, the Philadelphia Gay News grew into one of the nation's most respected LGBTQ+ newspapers during a pivotal era for the community. When the HIV/AIDS epidemic devastated gay Americans in the 1980s, the paper delivered urgent, groundbreaking coverage that mainstream outlets often ignored. Over the decades it became a driving force in the fight for LGBTQ+ visibility, rights, and marriage equality.

Philadelphia, PA · est. 2007

Founded in 1729 as an almshouse, Philadelphia General Hospital grew into the nation's longest-operating public health care institution, moving to this site in 1871. It became a cradle of American medicine: Dr. William Osler advanced clinical teaching here, and Alice Fisher, a protégée of Florence Nightingale, helped establish nursing as a trained profession. The hospital pioneered methods of cancer diagnosis and radiation therapy before it finally closed its doors in 1977.

Philadelphia, PA · est. 1992

Founded in 1907 by civic leader B.G. Collier, this Black fraternal lodge first gathered above a South Philadelphia barber shop before growing into an established institution. By 1913 it had moved to this site, and in 1923 the order erected its own building here. Fraternal orders like this offered Black Philadelphians mutual aid, fellowship, and a foothold of self-organized community life during the Jim Crow era.

Philadelphia, PA · est. 2008

Founded in 1860, the Philadelphia Sketch Club is the oldest artists' club in America, started by illustrators who discovered that gathering together to draw and talk sharpened both their skill and their eye. Over the decades its rolls read like a roster of American art, counting Thomas Eakins, Thomas Anshutz, and members of the Wyeth circle among its ranks. The club made social fellowship a working part of the creative life.

Philadelphia, PA · est. 1992

Christopher Perry launched the Philadelphia Tribune in 1884 as a single hand-printed page devoted to improving daily life for Black Americans. From that modest start it grew into an enduring institution and the oldest continuously published Black newspaper in the nation. For generations it chronicled the triumphs, struggles, and demands of Black Philadelphia when few other outlets would.

Brownsville, PA · est. 1946

Philander Knox was born here in Brownsville in 1853, in a house that still stood when this marker was placed. As Attorney General beginning in 1901 he became the government's leading trust-buster, wielding federal law against the great corporate combinations of the age. He went on to serve as a U.S. Senator and as Secretary of State under President Taft, shaping American diplomacy before his death in 1921.

College Township, PA · est. 1947

Ironmaster Philip Benner made his home at Rock, where he built one of the region's first forges in 1794 along with a nail and slitting mill. A founder of Bellefonte, he became a leading figure in Centre County's affairs until his death in 1832. His works helped establish the iron trade that would define the area for a century.

Benner Township, PA · est. 1947

In the young republic's early years, central Pennsylvania's forested valleys became iron country, and Philip Benner was among its pioneers. He built one of the region's first forges here in 1794, along with a nail and slitting mill, turning local ore and waterpower into finished iron at a time when the nation was hungry for it. A founder of nearby Bellefonte, he remained a driving force in Centre County affairs until his death in 1832.

Chambersburg, PA · est. 1953

Long before railroads criss-crossed the country, a Chambersburg man named Philip Berlin is credited with building the first American sleeping car for travelers. His car, fittingly named "Chambersburg," was running between Harrisburg and Chambersburg as early as 1838, in the very first years of American rail. He rests in the churchyard behind the marker.

Summit Hill, PA · est. 1991

According to long tradition, in 1791 the hunter Philip Ginter stumbled upon a black, burnable stone on Sharp Mountain here—anthracite, the hard coal that would power a nation. He carried his find to the settler Col. Jacob Weiss, and the next year Weiss and others formed the Lehigh Coal Mine Company, the first anthracite venture and a forerunner of the great Lehigh Coal & Navigation Company.

North York, PA · est. 1949

Philip Livingston, a wealthy New York merchant, put his name to the Declaration of Independence in 1776 and continued to serve in the Continental Congress until his death in June 1778, while Congress was meeting in York. He was buried here, hundreds of miles from home, a casualty of the demands of wartime public service. His grave lies about 300 feet west of this spot.

Rome, PA · est. 1947

Before he became one of the most beloved gospel songwriters of the 19th century, Philip P. Bliss taught school in Bradford County. He went on to write and lead singing at revival meetings across the country, penning hymns still sung today, until his life was cut short in 1876. So great was his following that Sunday school students in both England and the United States contributed the gifts that raised his cemetery monument.

Huston Township, PA · est. 1947

Philip P. Bliss was born in a log house near this spot in 1838 and grew up working the family farm and the region's lumber camps until he was sixteen. He went on to become one of the most beloved gospel songwriters and singing evangelists of the nineteenth century, his hymns carried into churches and revival meetings across the country. His life traced the arc from a rough Pennsylvania frontier boyhood to national renown.

Philadelphia, PA · est. 2003

Master silversmith Philip Syng, Jr. crafted the elegant silver inkstand that sat on the table at Independence Hall, used to sign both the Declaration of Independence and the Constitution. A close collaborator of Benjamin Franklin, he joined in Franklin's famous experiments with electricity and helped found civic institutions including the American Philosophical Society. His artistry and curiosity placed him at the heart of Philadelphia's revolutionary and scientific circles.

Philipsburg, PA

In 1797, the year the young United States was still finding its footing, twelve families pushed into the dense central Pennsylvania forest at the invitation of Henry Philips, who offered them free land. They settled along the Moshannon Creek among towering old-growth timber, carving out a foothold in country still shared with the Seneca followers of the Iroquois leader Cornplanter. The little settlement they raised, first called Moshannon Town, grew into the borough of Philipsburg.

Liberty Township, PA · est. 1966

In July 1780, as the Revolution's violence spilled across the Pennsylvania frontier, Captain William Phillips and eleven men of his militia company were captured near this spot by a Native war party. Ten were killed and later buried by a search party, while Phillips and his son Elijah were taken prisoner and not freed until the British released them at war's end.

Springfield Township, PA · est. 2006

On this site in the late 1930s, Philo T. Farnsworth ran experimental station W3XPF, conducting some of the earliest live local television broadcasts. Farnsworth had pioneered the all-electronic television system, and his relentless work in electronics earned him a long list of patents. He was later inducted into the National Inventors Hall of Fame.

Phoenixville, PA · est. 2005

For more than two centuries the ironworks at Phoenixville turned Schuylkill Valley ore and skill into the hard goods of a growing nation — nails and rail in the early years, then cannons and armor as the country went to war. The Griffen Gun of 1861 and the patented Phoenix Column of 1862 made the works a byword for American iron engineering, and its structural steel later helped raise buildings and bridges nationwide. The plant ran from the era of the young republic until it finally closed in 1987.

Plum, PA

This site in Plum, Pennsylvania once held a battery of a dozen Nike Ajax missile launchers, part of the ring of air-defense installations that guarded Pittsburgh's steel-making region during the early Cold War. Operational from 1955 to 1960, it belonged to a nationwide network built to shoot down Soviet bombers before they could reach America's industrial heartland. The launchers are long gone, but the ground where they stood recalls a tense chapter of homeland defense.

Manor, PA

At this location in Manor, Pennsylvania stood a Cold War Nike missile battery, its launchers later upgraded from the Ajax to the longer-range, nuclear-capable Hercules. Active from 1955 into 1968, it was one link in the chain of anti-aircraft sites encircling the Pittsburgh industrial area against the threat of Soviet air attack. Its long service life traces the evolution of American air defense across the height of the Cold War.

Picture Rocks, PA

In the small Loyalsock Creek village of Picture Rocks, tucked into the wooded ridges of Lycoming County, this memorial gathers the community's remembrance of the men and women who served in the nation's armed forces. Towns like this across rural Pennsylvania raised such monuments so that neighbors who left the valley for distant wars—and those who did not return—would keep a permanent place at the heart of local life. The simple pledge "Never Forgotten" speaks to that enduring bond between a small place and its service members.

Milford, PA · est. 1981

Split from Wayne County in 1814 and named for the explorer Zebulon Pike, this scenic northeastern county sent its bluestone and lumber to market by way of the Delaware & Hudson Canal and the Erie Railroad. Those materials helped build a growing nation even as the county became famed for its natural beauty. Near the seat of Milford stands Gray Towers, home of conservationist governor Gifford Pinchot.
