Historic Markers in Pennsylvania

Bethlehem, PA

Bethlehem grew up around steel — the mills and blast furnaces that built American bridges, skyscrapers, and warships also exacted a steady human toll in the men and women who worked them. Dedicated on April 28, 1991 — Workers Memorial Day, the date the modern labor movement set aside to honor those killed or hurt on the job — this memorial gathers that grief into a single place of remembrance. It speaks not for one industry but for every worker and the families left behind.

Bethlehem, PA · est. 2015

The rivalry between Lehigh and Lafayette began in 1884 at Lafayette College and became a defining fixture of the Lehigh Valley. Meeting more than 150 times, the two schools hold the NCAA's recognition for the most-played rivalry in college football. The annual clash has been chronicled in national outlets including Sports Illustrated and the New York Times and broadcast on ESPN.

Leidy Township, PA · est. 1995

In the winter of 1950, wildcatter Dorcie Calhoun ignored expert opinion and drilled deep into the hills of Leidy Township in search of natural gas. On January 8 his well struck gas at more than 5,600 feet, briefly gushing an estimated 15 million cubic feet a day. The strike made national news and set off a frenzy: within months more than thirty companies and independent operators were drilling across the township, chasing the boom before the field's production wound down.

Nether Providence Township, PA · est. 1955

Built in 1809-10 by Thomas Leiper and surveyed by John Thomson, the Leiper Railway ran about three-quarters of a mile to haul stone from quarries on Crum Creek down to a landing on Ridley Creek. It is remembered as the first railway in Pennsylvania and the first in America to be laid out by survey. Horses drew the loaded cars along its wooden rails decades before the steam locomotive age.

Cresson Township, PA · est. 1958

Samuel Lemon built this stone tavern in 1830 at the summit of the Allegheny Portage Railroad, beside the head of Inclined Plane No. 6. The Portage was an engineering marvel that hauled canal boats up and over the mountains by a series of cable-worked inclines, knitting Philadelphia to Pittsburgh. For years the Lemon House gave weary travelers, teamsters, and railroad crews a place to rest, eat, and water their horses at the roof of the crossing.

South Strabane Township, PA · est. 1953

In 1876 Dr. Francis Julius LeMoyne, a physician and reformer, built the first crematory in the United States on this ground, convinced that cremation was more sanitary than traditional burial in crowded, disease-prone cemeteries. Between 1876 and 1900 the facility performed 42 cremations, a modest number that nonetheless launched a national conversation about death, public health, and reform. LeMoyne himself was cremated and lies buried at the site.

Washington, PA · est. 1953

Built in 1812 in the young town of Washington, this brick house became the home of Dr. Francis Julius LeMoyne, a physician remembered as one of western Pennsylvania's most outspoken abolitionists in the decades before the Civil War. LeMoyne pushed his convictions in directions few contemporaries dared, later erecting the first crematory in the United States and championing public education and reform. The house survives as the home of the Washington County Historical Society, keeping that reform-minded legacy in place.

Philadelphia, PA · est. 2021

Leopold Stokowski led the Philadelphia Orchestra from 1912 to 1941, transforming it into one of the world's most celebrated ensembles. Charismatic and inventive, he cultivated the lush, distinctive tone known as the "Philadelphia Sound" and worked tirelessly to bring classical music to ordinary audiences. His collaboration on Walt Disney's Fantasia and his many recordings carried symphonic music far beyond the concert hall.

Limestone Township, PA · est. 1947

On October 16, 1755, John Jacob Leroy was killed by Indians near this site, one of the earliest victims of frontier warfare in the region. His death came just after the Penn's Creek Massacre and in the wake of General Braddock's disastrous defeat, events that shattered the fragile peace and opened years of bloody conflict during the French and Indian War. Central Pennsylvania's exposed settlements suddenly found themselves on the front line.

Porter Township, PA · est. 2006

Born in the small coal-country town of Reinerton, Les Brown built a seven-decade career at the center of American popular music. His orchestra, the 'Band of Renown,' backed a young Doris Day on the chart-topping 'Sentimental Journey,' a song that became an anthem for a nation longing for loved ones to come home from war. Brown went on to serve for decades as bandleader for Bob Hope and Dean Martin, a fixture of American stage and television.

Wysox Township, PA · est. 1967

Lester Frank Ward (1841–1913) spent his youth in this corner of Bradford County, working alongside his brother Cyrenus in a small hub factory before the Civil War, in which he served. He went on to become a pioneering geologist and paleobotanist and the founding figure of American sociology, arguing that human societies could be improved through reason and planning. So sweeping was his intellect that admirers dubbed him "the American Aristotle."

Tullytown, PA · est. 1992

When the first family moved in on June 23, 1952, they joined a bold experiment in mass housing conceived by builder William J. Levitt. Following the assembly-line model he had pioneered at Levittown, New York, Levitt raised more than 17,000 homes on 5,750 acres of Bucks County farmland, a community planned for 70,000 residents and finished in 1957. Affordable and quickly built, its uniform streets became a symbol of postwar America's rush to the suburbs.

Pittsburgh, PA · est. 2008

On August 31, 1803, Meriwether Lewis eased a 50-foot keeled boat into the Ohio River near Fort Fayette, launching the journey that would become the Lewis and Clark Expedition. Commissioned by President Thomas Jefferson to explore the newly acquired lands to the west, the three-year trek pushed all the way to the Pacific and back. Pittsburgh, at the head of the Ohio, was the practical starting line for that continental adventure.

Brookville, PA · est. 2009

In 1912, only a few years after the Wright brothers first flew, Lewis Sandt of Brookville climbed into a fragile early aircraft and flew from Erie into Canada — the first international flight by an American. The feat thrilled crowds and helped fire the public's imagination for aviation. Like so many pioneer aviators, Sandt paid the ultimate price, dying of crash injuries the following year at just twenty-five.

Ellwood City, PA · est. 2023

Lewis "Hack" Wilson grew up in the industrial town of Ellwood City before carrying its working-class grit into the major leagues, where he starred as a slugging outfielder across twelve seasons beginning in 1923. His 1930 campaign with the Chicago Cubs became the stuff of legend: 56 home runs, a National League mark that endured for 68 years, and 191 RBIs, a single-season record that still stands. He retired in 1934 and, decades later, took his place in the Baseball Hall of Fame.

Lewisburg, PA · est. 1955

When Pennsylvania built its sprawling state canal system in the 1820s and 1830s to link its rivers and markets, short connecting cuts often did the crucial work of tying a town into the network. Completed in 1833, this five-eighths-mile cross-cut with three lift locks and a slackwater dam let canal boats cross the Susquehanna and reach Lewisburg, turning the town into a busy shipping point. In the canal era, such a modest ditch could mean the difference between a sleepy village and a thriving trade center.

Granville Township, PA · est. 1996

Built in 1848-49 as a freight warehouse, this is the oldest surviving structure known to have been raised by the mighty Pennsylvania Railroad — the company that would become one of the largest corporations on earth. Its opening was toasted at a banquet in September 1849 celebrating the rails' arrival in Lewistown, part of the great mid-century push to lace the state with iron. By 1868 the freight house had been remade into a passenger station, greeting travelers where goods once moved.

Harrisburg, PA · est. 2021

In 1975 Governor Milton Shapp made Pennsylvania a national trailblazer, becoming the first U.S. governor to bar discrimination against LGBTQ+ state employees. He created the Pennsylvania Council for Sexual Minorities — the first government body in the nation devoted to LGBTQ+ policy — and issued a proclamation for Gay Pride Week in 1976. He later extended the nondiscrimination policy to companies holding state contracts.

Allentown, PA · est. 2022

In the anxious autumn of 1777, with the British army marching on Philadelphia, the Continental Congress ordered the city's bells spirited away so they couldn't be melted into cannon. The great State House bell traveled north by wagon and rested for months beneath the floorboards of Zion's Reformed Church here in Allentown before returning home in 1778. Decades later, antislavery reformers seized on its inscription—'Proclaim liberty throughout all the land'—and renamed it the Liberty Bell, turning a cracked colonial bell into an enduring emblem of freedom.

Upper Merion Township, PA

In the tense years before the Revolution, colonists across the thirteen colonies singled out great elms and other spreading trees as "Liberty Trees" — public gathering places where the Sons of Liberty rallied crowds against British rule. The tradition began with Boston's famous elm during the 1765 Stamp Act protests, where colonists hung effigies of royal officials from its branches, and the idea spread from town to town. Beneath these trees, ordinary people met, argued, and organized, turning a living landmark into a shared symbol of resistance. A memorial like this one in Upper Merion keeps that tradition of the patriot "tree of liberty" rooted in local memory.

West Pikeland Township, PA · est. 2007

Samuel Lightfoot built this water-powered grist mill around 1747 to grind feed and grain for his Chester County neighbors. It is a rare survivor of the colonial custom mill, with its horizontal counter-shaft power system still intact—a snapshot of early American industrial technology. The mill kept working into the 1930s and is now a National Historic Landmark cared for by a preservation trust.

Duncannon, PA · est. 1992

From 1904 to 1988, the Standard Novelty Works in Duncannon turned out the beloved Lightning Guider sled, and by 1920 the plant was reputedly making more children's sleds than any other factory in the country — up to 1,800 a day. Founded by William Wills and P.F. Duncan, it also produced wagons, porch swings, gates, and furniture before closing in 1990. For much of the 20th century, winter fun for American children rode on runners made in this small Perry County town.

Wyalusing Township, PA · est. 1947

On April 14, 1782, a small party led by Sergeant Thomas Baldwin came to this ground trying to free a woman and her children held captive by Native raiders — a common and wrenching feature of frontier war. The rescue turned into a four-hour fight. Three of the children were saved, but the mother was killed before they could reach her. The episode captures the intimate violence of the Revolution's final years along the Susquehanna.

Wyalusing Township, PA · est. 1928

On April 14, 1782, near this spot, Sergeant Thomas Baldwin's party tried to overtake a Native war band that had captured Mrs. Rosewell Franklin and her four children. After some four hours of fighting from hastily thrown-up breastworks, the rescuers freed three of the children, but Mrs. Franklin was killed. The skirmish was one of the last violent episodes of the Revolutionary frontier in the Wyoming country.

Cumberland Township, PA

This monument in the Gettysburg National Cemetery grounds commemorates Abraham Lincoln's Gettysburg Address, delivered on November 19, 1863, about 300 yards away during the cemetery's dedication. In barely two minutes and 272 words, Lincoln recast the war as a test of whether a nation 'conceived in liberty' could endure, and rededicated the living to 'a new birth of freedom.' The actual spot of the speech is marked nearby by the Soldiers' National Monument.

West Chester, PA · est. 1952

In February 1860, as the nation edged toward disunion, the first published biography of Abraham Lincoln came off a press in this West Chester building. Drawn from Lincoln's own notes, the campaign biography introduced a still little-known prairie lawyer to eastern readers just as he was emerging as a presidential contender. Such biographies were a key tool of 19th-century politics, shaping how voters met a candidate they would never see in person.

Progress, PA · est. 1994

Founded in 1827 by the Wesley Union A.M.E. Zion Church, this cemetery became a resting place for central Pennsylvania's Black community across generations. Among its graves are those of journalist and Civil War officer T. Morris Chester, educator and abolitionist William Howard Day, and more than twenty Civil War veterans. Each headstone marks a life that helped build free Black institutions in the decades around emancipation.

Gettysburg, PA · est. 2003

Founded in 1867 by the Sons of Good Will, Lincoln Cemetery gave Gettysburg's African American citizens and soldiers a dignified resting place they were otherwise denied. Roughly thirty veterans of the United States Colored Troops lie here — men who fought for the Union but were barred by segregation from burial in the town's famous National Cemetery. Later generations of Black veterans from the Spanish-American War through Korea joined them in ground first known as Good Will Cemetery and renamed for Lincoln in 1920.

Columbia, PA · est. 2003

In 1913 the Lincoln Highway Association stitched together existing roads into the nation's first coast-to-coast route, running from New York to San Francisco. The highway transformed American travel, and towns along it sprouted filling stations, tourist cabins, and roadside restaurants to serve the new motorists. In 1925 much of its Pennsylvania path was folded into Route 30.

Exeter Township, PA · est. 1947

In 1733 Mordecai Lincoln—great-great-grandfather of President Abraham Lincoln—bought land in Exeter Township and built a stone house that still stands a little over a mile south of here. He served as a Berks County justice of the peace and moved in the same circle as the Boone family, being a friend of George Boone Jr., uncle of the pioneer Daniel Boone. Generations later, Lincoln himself wrote of his forebears from Berks County, Pennsylvania.

Honesdale, PA · est. 1968

In May 1859, the influential editor Horace Greeley reportedly met with political allies in this building to lay groundwork for an unlikely presidential bid by Abraham Lincoln. The maneuvering echoed the coalition-building that would carry Lincoln to the Republican nomination at the 1860 Chicago convention. Such backroom parleys were where the anti-slavery Republican Party's strategy took shape on the eve of the sectional crisis.

Lower Oxford Township, PA · est. 1967

Chartered in 1854 as the Ashmun Institute, this school was founded by the Rev. John Miller Dickey to provide higher education to men of African ancestry at a time when almost no such opportunity existed in America. Renamed Lincoln University in 1866, it opened its doors as an interracial and international institution. It became one of the nation's first degree-granting historically Black colleges, educating generations of leaders across the United States and Africa.

Lititz, PA · est. 1980

Founded in 1746 by the Moravian Church in the tight-knit religious community of Lititz, Linden Hall is the oldest girls' resident school in the United States. The Moravians, German-speaking Protestants known for their devotion to education, believed girls deserved rigorous schooling at a time when few Americans agreed. What began as a day school grew after 1794 into a boarding academy drawing students from far and wide, and was chartered under its present name in 1863.

East Hanover Township, PA · est. 1947

Lindley Murray was born in 1745 in a house along Indiantown Creek, where his father Robert briefly ran a mill. He grew up to become one of the most influential grammarians in the English-speaking world; his English Grammar, first published in the 1790s, was reprinted countless times and drilled into generations of schoolchildren on both sides of the Atlantic. From these modest Lebanon County beginnings came the author whose rules of usage governed classrooms for the better part of a century.

East Hanover Township, PA · est. 1947

Near this spot in 1745 Lindley Murray was born, the son of Robert Murray, who kept a mill here for a short time. Murray became the most widely read grammarian of his age, and his English Grammar shaped how students were taught to read and write for generations. A boy from the Pennsylvania backcountry thus became a household name in schoolrooms across America and Britain.

Marion Center, PA · est. 2008

Born in Marion Center in 1826, Linton Park became one of America's most significant folk painters, capturing rural western Pennsylvania with an unschooled but vivid eye. His best-known canvas, "The Flax Scutching Bee" (1847), preserves a vanished frontier custom, while his logging scenes document the early lumber industry. Through his art, everyday labor and community traditions of the 19th-century backcountry survive as historical record.

Lititz, PA · est. 1967

Settled in the 1740s, Lititz became in 1756 a Moravian "Land Gemeine," a tightly knit country congregation that ordered the town's land, trades, and worship around its church. Count Zinzendorf, the Moravians' great patron, named it for a Bohemian town that had sheltered persecuted brethren back in 1456—binding this Pennsylvania village to centuries of European religious exile. The result was one of America's distinctive planned Moravian communities.

Shenandoah, PA · est. 2013

Since the late 1800s, the coal fields around Shenandoah drew Lithuanian immigrants in such numbers that Schuylkill County holds the greatest concentration of Lithuanian ancestry in the United States. Lured by work in the anthracite mines, they built churches, societies, and one of the nation's oldest Knights of Lithuania chapters to preserve their language and faith. The Rev. Andrius Stupinskas, who led one of the first Lithuanian American Catholic congregations in 1872, rests in the local St. George cemetery.

Philadelphia, PA · est. 2025

Local 8 of the Industrial Workers of the World organized Philadelphia's waterfront dockworkers from 1913 to 1923, growing into one of the country's largest and most powerful unions. Under the leadership of Ben Fletcher, it stood out as a Black-led, multiracial local that deliberately united workers across ethnic and racial lines. It fought for better wages, safer conditions, and a solidarity that crossed the color line at a time when most unions did not.

Alburtis, PA · est. 2009

Built in 1868, the Lock Ridge Iron Furnace was one of scores of furnaces that made the Lehigh Valley the state's greatest producer of pig iron in the late 19th century. Distinctively, it burned only anthracite — the hard coal that fueled Pennsylvania's iron boom — and was the last furnace in the country to rely on it alone before closing in 1921. Today its partially restored stacks are among the few surviving monuments to that vanished industry.

Shippensburg, PA · est. 2007

Since the early 19th century, Locust Grove Cemetery has been the resting place of enslaved and free Black residents of the Shippensburg area, and the site of the town's first African American church, founded in the 1830s. In 1842 Edward Shippen Burd granted the land to the local Black community, and for well over a century it remained the only public cemetery in the area open to African Americans. Among its graves are twenty-six Civil War soldiers, alongside veterans of every American conflict through Vietnam.

Warminster Township, PA · est. 2008

Around 1735, the Reverend William Tennent built a humble log schoolhouse here and began training Presbyterian ministers — the first academy of its kind in America and the first college in Pennsylvania. Detractors mocked the rustic building as a "Log College," but it became a seedbed of the religious revival known as the Great Awakening. When Tennent died in 1746 the school closed, but its graduates soon helped found what became Princeton University.

Jennerstown, PA · est. 1947

In 1805 a miller named Cronin raised a log grist mill at Roxbury, part of the network of small water-powered mills that ground the grain of frontier Pennsylvania into flour and meal. The mill turned for well over a century, staying in operation until 1918 before its working days ended. Later reconstructed, the sturdy log building found new life as the Mountain Playhouse, preserving a fine example of early American milling.

Altoona, PA · est. 1947

In September 1862, with the Civil War at a grim turning point, the governors of the loyal Northern states gathered at the Logan House, a famous railroad hotel that once stood on this site. Pennsylvania's Governor Andrew Curtin called the conference, and the assembled governors pledged their states' support to President Lincoln at a moment when he was preparing the Emancipation Proclamation. Their united stand helped steady the Union war effort.

Harmony Township, PA · est. 1946

Logstown was one of the great Native towns of the upper Ohio, home between 1727 and 1758 to a mix of Iroquois, Delaware, Shawnee, and other peoples. Its council fires drew British and French agents alike, each competing for Indian alliances as the two empires maneuvered for control of the Ohio Country. The conferences held here helped set the stage for the French and Indian War.

Pittsburgh, PA · est. 2019

Lois Weber was born on this Pittsburgh site and grew up to become the first American woman to direct films—and one of the most prolific and daring directors of the silent era. Between 1908 and 1934 she wrote, directed, and acted in more than two hundred pictures, tackling controversial subjects like drug addiction, abortion, and poverty that most filmmakers avoided. She also helped pioneer cinematic techniques, including the split screen.

Philadelphia, PA · est. 2005

On August 1, 1842, Philadelphia's Black community gathered to celebrate the anniversary of emancipation in the British West Indies—a hopeful marker of freedom in a nation where slavery still reigned. A white mob descended on the peaceful parade, and over three days of violence African Americans were beaten, their homes ransacked, and a church and abolitionist meeting hall burned to the ground. The Lombard Street Riot was one of a wave of anti-Black assaults that convulsed the antebellum city.

Philadelphia, PA · est. 1991

Opened in 1754, the London Coffee House was a hub of colonial Philadelphia's political and mercantile life, where traders, officials, and townsfolk gathered to talk business and news. But its bustling floor carried a darker function: enslaved Africans, newly arrived by ship, were inspected and sold here at public auction. The site captures the uncomfortable truth that even in the cradle of American liberty, commerce and human bondage stood side by side.

Sunbury, PA · est. 1994

Lorenzo Da Ponte had already lived an extraordinary life as Mozart's librettist — writing the words for The Marriage of Figaro, Don Giovanni, and Così fan tutte — before he emigrated to America in 1805. From 1811 to 1818 he made his home in Sunbury, his wife's family's town, working as a teacher, distiller, and merchant, and declaring himself so taken with the place that he resolved to settle there.

Philadelphia, PA · est. 2010

Born on this spot, Lorenzo L. Langstroth transformed beekeeping with his 1852 patented movable-frame hive, whose precise "bee space" let keepers inspect and harvest without destroying the colony. His widely read manual, The Hive and the Honey-Bee, spread the method around the globe. Both the hive design and the book remain in use, earning him the title "father of modern beekeeping."

Cresson Township, PA · est. 1947

The village of Loretto, a few miles from this marker, was founded in 1799 by Prince Demetrius Gallitzin as a Catholic colony on the Allegheny frontier. The priest-missioner who gave his life to the settlement is buried there, and generations later the steel magnate Charles Schwab made his home in Loretto and was laid to rest in the same ground. The place links the earliest days of frontier faith to the towering ambitions of the industrial age.

Allegheny Township, PA · est. 1948

Loretto owes its founding in 1799 to Demetrius Gallitzin, a Russian-born prince who gave up nobility to become a Catholic missionary priest on the Pennsylvania frontier. He opened a school here at the dawn of the new century, planting a seed that grew into Saint Francis College and made this remote settlement an enduring Catholic cultural center. Generations later the steel magnate Charles M. Schwab kept a grand home in the same hills.

Olyphant, PA · est. 1995

On March 21, 1917, just sixteen days before the United States formally entered World War I, Loretto Perfectus Walsh became the first woman to enlist in the U.S. Navy, serving as a Chief Yeoman (F) in Philadelphia. Born in Olyphant in 1896, she was part of a wave of women who stepped into naval clerical and support roles so that men could be sent to the front. Discharged in 1919, she died young in 1925, but her enlistment marked a genuine milestone.

Philadelphia, PA · est. 2004

Louis I. Kahn ranks among the most influential architects of the postwar era, a designer who treated mass, light, and structure as the very substance of his buildings. Trained in the Beaux-Arts tradition at the University of Pennsylvania, he later taught there and ran his practice from this location, producing monumental works admired around the world. His buildings are known for their weighty, almost ancient presence married to a modern sense of purpose.

Philadelphia, PA · est. 1996

Louisa May Alcott, who would write the beloved "Little Women," was born at "Pine Place" on November 29, 1832, to the visionary educator Bronson Alcott and his wife Abigail. Her family lived in this county during her earliest years before moving on to New England. Beyond her enduring children's fiction, Alcott served as a Civil War nurse and threw herself into the great reform causes of abolition and women's suffrage.

Highland Township, PA · est. 1948

This congregation gathered in 1748, when Scots-Irish Presbyterian families were settling the rolling country of what is now Adams County on the colonial frontier. The present meetinghouse rose in 1790, and though later remodeling altered it, the building still carries the plain, sturdy lines of its eighteenth-century origins. Churches like this anchored the social and spiritual life of frontier communities long before towns grew up around them.

Upper Darby, PA · est. 1989

This modest log structure is the last survivor of several cabins that once lined Darby Creek, built by Swedish colonists who settled the lower Delaware Valley after New Sweden was founded in 1638. Its notched-log construction is a direct link to that short-lived Scandinavian colony, whose building style influenced American frontier architecture. Centuries later the cabin found a second life as a film set, used by Philadelphia motion-picture pioneer Siegmund Lubin for several movies before 1910.

Ligonier Township, PA · est. 1946

Along a stream the Delaware (Lenape) named for its "middle" waters, a Native village took root as the nation shifted westward out of the Susquehanna Valley in the late 1720s. Pushed by mounting colonial pressure to the east, these families relocated into the Loyalhanna country of the Pennsylvania uplands, carrying their language and place-names with them. The site marks one link in the long story of Indigenous movement across a landscape being reshaped by European settlement.

Newtown, PA · est. 2001

On February 19, 1778, with the British holding Philadelphia and Washington's army wintering at Valley Forge, roughly 40 armed Loyalists raided the tavern that stood here. The fighting left five American soldiers dead, four wounded, and eleven captured. Tailors working at the site had been sewing uniforms for the troops at Valley Forge, and some 2,000 yards of cloth were carried off.

State College, PA

Lieutenant Michael P. Murphy was a Navy SEAL and 1998 Penn State graduate who died on June 28, 2005, in the mountains of eastern Afghanistan during Operation Red Wings. Pinned down with his four-man reconnaissance team, he moved into open ground under heavy fire to get a clear signal and call for help — a decision that cost him his life but became the stuff of legend. In 2007 he was posthumously awarded the Medal of Honor, the first given for service in the Afghanistan war. The plaza carries a Greek line long attributed to Spartan mothers, 'with your shield or on it,' binding an ancient ideal of sacrifice to a modern one.
