Historic Markers in Pennsylvania

Hamilton Township, PA

This weathered gravestone in Hamilton Township, in Pennsylvania's Monroe County, marks the burial of seventeen-year-old Etna Bittenbender, daughter of Samuel and Margaret, whose epitaph records that she was murdered by an unknown assailant one Sunday evening. Such starkly specific inscriptions were a 19th-century way of memorializing an unsolved crime in stone. The precise phrasing—naming the very hours of the deed—preserves a community's shock at a young life cut short.

Carbondale, PA · est. 1999

Built in 1828–29, this gravity railroad was among the first in the Western Hemisphere, engineered to haul anthracite coal to the Delaware & Hudson Canal for shipment to market. Its line ran from Honesdale and was extended over the years toward Archbald and beyond to Valley Junction near Olyphant. Later carrying passengers as well as coal, it operated until the very start of 1899.

Henry Clay Township, PA · est. 1947

This bend of the Youghiogheny had served as a fording place since Native peoples first traced paths through the mountains. In 1754 young George Washington's Virginia troops camped here on the eve of the frontier clashes that opened the French and Indian War, and the next year Braddock's ill-fated army tramped through on its march west. Decades later, in 1818, the National Road threw a bridge across the water at this very spot, cementing its role as a great gateway through the Alleghenies.

Manor Township, PA · est. 1951

This was the great artery of the mid-17th-century fur trade, the chief trail by which the Minqua—also known as the Susquehannock—carried beaver pelts eastward to the European settlements along the Delaware. The trade was so lucrative that the Swedes, Dutch, and English fought one another to control it. The path traced a route of immense commercial and political importance in the early contest for the region.

West Goshen Township, PA · est. 1951

In the 1600s, before English rule was secure, the Great Minquas Path was one of the most valuable trails in the region — the key artery of the fur trade linking Native towns of the interior with trading posts on the lower Schuylkill. Along it flowed the beaver pelts that made the Delaware Valley a prize, and the Dutch, Swedes, and English each struggled to control it. The path crossed near this spot, a quiet reminder of a contest for commerce and empire.

Salisbury Township, PA · est. 1951

An ancient Indian path once ran through the Gap just south of here, later becoming the original Conestoga Road. In the 17th century the Minquas—the Conestoga—used it to carry great quantities of beaver skins from the Susquehanna Valley to the trading posts near Philadelphia. What began as a Native trail hardened over time into one of the region's foundational overland routes.

Delaware Township, PA · est. 1949

The Great Shamokin Path was once the main Indian highway west, running from Shamokin—now Sunbury—toward the Ohio country. Along it traveled the Delawares (Lenape) as they were pushed out of their eastern Pennsylvania homelands by the pressure of colonial settlement. After the crushing defeat of General Braddock in 1755, Delaware warriors used this very trail to strike back at the frontier settlements during the French and Indian War.

Liberty Township, PA · est. 1950

The Great Shamokin Path was one of the major Native thoroughfares across Pennsylvania, running from Shamokin — now Sunbury — westward to the Delaware town of Kittanning on the Allegheny. Near here it left the Bald Eagle Valley to follow Marsh Creek and Little Marsh Creek, then climbed the Allegheny Front by way of Snow Shoe and Moshannon. The route reveals how Indigenous travelers read the landscape, choosing creek valleys and mountain gaps to cross rugged terrain.

Bald Eagle Township, PA · est. 1950

In 1772, the Moravian missionary Bishop John Ettwein led some 200 Christian Mohican and Delaware converts along the Indian path beside Bald Eagle Creek. They were journeying from the mission town of Friedenshuetten, near Wyalusing, to a new settlement called Friedensstadt on the Beaver River. The trek carried whole families through the Pennsylvania interior in search of a place to live out their faith in peace.

Bell Township, PA · est. 1950

The Great Shamokin Path was a major Indian thoroughfare linking the Susquehanna and Allegheny rivers, running near this spot long before European roads followed the same ground. Delaware and Shawnee people used it for hunting and trade, and warriors traveled it during the French and Indian War. In July 1772 the Moravian missionary Bishop John Ettwein led some 200 Native Americans and their cattle along this stretch as they migrated west to the settlement of Friedensstadt.

Carlisle, PA · est. 1949

In the mid-18th century Carlisle sat at the edge of the Pennsylvania frontier, a gateway where colonial officials met with Native nations to negotiate land and trade. An inn on this site hosted Benjamin Franklin in 1753 while he and fellow commissioners treated with Indians, and four decades later it lodged Alexander Hamilton and Henry Knox as Washington's cabinet passed through during the Whiskey Rebellion. A single roadside tavern thus touched both the colonial diplomacy of the 1750s and the young republic's first test of federal authority.

Chester, PA · est. 1954

"Green-Bank" was the name given to a house built on this site in 1721 by David Lloyd, a leading figure in colonial Pennsylvania. In later years it was home to the distinguished Porter naval family and a place the celebrated Admiral David Farragut is said to have visited, until the house was destroyed in 1882 by the disaster remembered as the "Jackson Explosion."

Philadelphia, PA · est. 2007

Built in 1956 amid the woods of Pennypack Park, Greenbelt Knoll was the first racially integrated housing development in Philadelphia — and a model for the nation at a time when housing discrimination was the norm. Developer Morris Milgram, a committed civil rights advocate, gathered noted architects, among them Louis Kahn, to design Modernist homes that blended into the natural landscape. Its first residents were themselves a statement, including Milgram, U.S. Rep. Robert N.C. Nix, and the Rev. Leon Sullivan.

Carmichaels, PA · est. 1953

Established by act of the Pennsylvania legislature in 1810 and aided by a state grant and local subscriptions, Greene Academy brought advanced schooling to Carmichaels when much of western Pennsylvania was still frontier country. For half a century it stood among the leading academies west of the mountains, educating young people far from the older schools of the East. Its old building still stands nearby.

Waynesburg, PA · est. 1982

Formed from Washington County in 1796, Greene County was named for Revolutionary War general Nathanael Greene, and its seat, Waynesburg, honors the fiery General Anthony Wayne. In the southwestern corner of Pennsylvania, this was hard-won frontier country in the early republic. Waynesburg College was founded here in 1849, and the area near Ten Mile Creek gave rise to Governor Edward Martin.

Pittsburgh, PA · est. 2009

In 1932, Pittsburgh numbers baron Gus Greenlee built something no Black baseball owner had ever possessed: his own ballpark. From 1932 to 1938, Greenlee Field was the first African American–owned stadium in the Negro Leagues and home to his Pittsburgh Crawfords, the 1935 league champions. Its diamond hosted some of the greatest players in the sport's history — Hall of Famers Satchel Paige, Josh Gibson, and Cool Papa Bell among them.

Jackson Township, PA · est. 1947

Built about 1837 to supply iron to Freedom Forge near Lewistown, Greenwood Furnace grew into a self-contained iron-making village typical of central Pennsylvania's charcoal iron era. Its restored stack, church, 'Big House,' and company store survive as reminders of the tight-knit communities that formed around these rural industrial works. When the furnace closed in 1904, it was the last of its kind still operating in the region, marking the end of an industrial age.

Young Township, PA · est. 2004

German immigrants who settled this corner of Jefferson County brought with them an old European folk custom tied to Candlemas, a Christian festival on February 2 that people used to forecast the remaining weeks of winter. By 1886 the tradition had taken root here, and in 1899 locals founded the Punxsutawney Groundhog Club, elevating a hibernating groundhog named Phil into a weather prophet. The ritual—if Phil sees his shadow, six more weeks of winter—grew into one of America's most beloved and quirky annual observances.

Cornwall, PA · est. 1967

Around 1735, Peter Grubb began working iron just north of here, launching an enterprise that would help make Pennsylvania a colonial iron powerhouse. He relied on the Catalan-type forge—a bloomery method with roots in tenth-century Spain—to draw usable iron from ore. Grubb's early efforts seeded the great Cornwall ironworks that followed.

Upper Merion Township, PA · est. 1982

This roughly 1780 house recalls the small crossroads settlement once known as Bird-in-Hand, named for the sign of a nearby tavern in the old English fashion. For years the building served as the Bird-in-Hand General Store, a gathering point for a community that also supported a forge just to the southwest. As the trades that sustained the village faded, both the store and the forge were quietly converted into homes — a common fate for early industrial hamlets swallowed by suburban growth.

Philadelphia, PA · est. 2023

Founded in the 1950s by Dawud Hakim, this Philadelphia shop was the city's first Black-owned bookstore devoted to Black history and authors—a place where readers could find their own story on the shelves. Through the 1960s it became a gathering point for civil rights organizing and Black activism. That prominence also drew the eye of the FBI, which surveilled Hakim's along with other Black bookstores of the era.

Philipsburg, PA

In 1813, when central Pennsylvania was still rugged frontier, the English-born Hardman Philips raised a grand 25-room country seat he called Moshannon Hall—later Halehurst—on land near the town his family helped establish. His brother Henry had founded Philipsburg in 1797, part of a wave of English gentry-industrialists who came to the Moshannon valley to develop its timber and iron. A mansion with thirteen fireplaces was an extravagant statement of permanence and status in a place only recently carved out of the wilderness.

York, PA · est. 1949

On this site stood the first printing press west of the Susquehanna River, operated by the firm of Hall and Sellers. When the Continental Congress fled to York from September 1777 to June 1778, this press turned out government publications and Continental currency for the struggling revolutionary cause. It was during Congress's stay here that the Articles of Confederation were adopted, making York briefly the seat of the young nation.

Crafton, PA · est. 1946

During the Revolutionary War, the frontier post of Fort Pitt guarded the vital forks of the Ohio, and disease was a constant threat to its garrison. In 1777 General Edward Hand ordered an isolation hospital built on this site to treat and quarantine sick and wounded troops, its log structure ringed by protective blockhouses. The precaution reflected the era's hard-won understanding that contagion could cripple an army as surely as any enemy.

Philadelphia, PA · est. 2000

Hannah Callowhill Penn married William Penn in 1696 and shared his life in Pennsylvania, including two years at the Slate Roof House in Philadelphia at the turn of the eighteenth century. When a stroke left her husband incapacitated in 1712, she took up the reins of the colony he had founded, and after his death in 1718 she governed as acting proprietor until her own death in 1726. For roughly fourteen years she managed the affairs of Pennsylvania — no other woman controlled a British proprietary colony for so long.

Hempfield Township, PA · est. 1946

Just east of here stood Hannastown, established in 1773 as the seat of Westmoreland County and the first county seat west of the Allegheny Mountains. Its citizens gathered in 1775 to adopt a bold declaration backing the Revolutionary cause, an early frontier voice for independence. In 1782, near the end of the war, a raiding party burned the town, and it never fully recovered.

East Hanover Township, PA · est. 1947

Two miles north stood one of the region's pioneer Presbyterian congregations, founded in 1736 under its first pastor, Richard Sankey. Its graveyard became the resting place of the valley's earliest settlers alongside men who fought in the frontier wars and the Revolution that followed. A country churchyard like this is a layered record of the community that grew up around it.

North Codorus Township, PA · est. 1953

In November 1863, this rural railroad junction in York County was where Abraham Lincoln's train changed lines on his way to dedicate the national cemetery at Gettysburg. Months earlier the same junction had funneled wounded men from the battlefield onward to distant hospitals, and it served as a key relay on the military telegraph network that carried war news north and east. What looks like an ordinary spot where two rail lines met was, for a season, a nerve center of the war in Pennsylvania.

East Hanover Township, PA · est. 1946

On June 4, 1774, Col. Timothy Green and eight fellow patriots of Hanover Township drew up what the marker calls the earliest resolves for independence in Pennsylvania. Written more than two years before the Declaration, their bold pledge to commit their cause to "Heaven and our Rifles" captured the defiant mood spreading through the colonial countryside. Such local resolves gave voice to ordinary communities determined to resist British authority.

Somerset, PA · est. 1947

Harmon Husband arrived in the Somerset country as its first settler after fleeing North Carolina in 1771, where he had helped lead the Regulator uprising against colonial authority. Living for a time at his Coffee Springs farm, he never abandoned the cause of common people against government overreach, taking up his pen as a pamphleteer. In the 1790s he threw himself into the Whiskey Rebellion, the western Pennsylvania revolt against the federal excise tax, before his death in 1795.

Jackson Township, PA · est. 1947

This walled ground holds the graves of members of the Harmony Society, the German pietist commune that settled here between 1805 and 1815. In keeping with their beliefs the graves were left unmarked, plain and equal in death as the Harmonists sought to be in life. The stone wall came later, in 1869, built after the society had returned from its sojourn in Indiana and settled at "Old Economy" in Beaver County.

Harmony, PA · est. 1947

The town of Harmony was the first American home of the Harmony Society, a communal religious settlement founded in 1804 by George Rapp and his German followers. Seeking to live simply and hold property in common while awaiting the millennium, the Harmonists prospered here before moving west to New Harmony, Indiana, in 1814. A decade later they returned to Pennsylvania, settling at Economy in present-day Ambridge in 1825.

Jackson Township, PA · est. 1947

In the years after the German Harmonist communal society moved on from western Pennsylvania, Abraham Ziegler bought their property and, in 1816, organized a Mennonite congregation here in Butler County. The Rev. John Boyer served as its first pastor, and by 1825 the worshippers had raised the sturdy stone church that still marks their presence. It is a quiet reminder of the layered German religious settlement that shaped this corner of the frontier.

Ambridge, PA · est. 1963

This ground holds the graves of 594 members and workers of the Harmony Society, the German pietist community whose nearby village of Old Economy was one of America's most successful communal experiments. Led by their faith in a coming millennium, the Harmonists lived and labored together, prospering in farming and manufacturing while practicing celibacy. Their unmarked burials reflect the plain, self-effacing devotion at the heart of the society.

Ambridge, PA · est. 1967

Between 1828 and 1831 the Harmony Society—German Pietist immigrants who followed George Rapp in a communal, celibate religious life—raised this brick church at their town of Economy. The members made the bricks themselves, and the building, believed designed by Frederick Rapp, became the spiritual heart of one of America's most successful utopian communities. The Harmonists blended fervent millennial faith with shrewd industry, prospering while awaiting the Second Coming.

Forksville, PA · est. 1999

Harold 'Red' Grange — the 'Galloping Ghost' — was born in Forksville, where his family farmed and worked the nearby lumber camps before moving away when he was five. He became a three-time All-American at the University of Illinois and, from 1925 to 1934, one of professional football's first great draws, chiefly with the Chicago Bears. A member of the College Football Hall of Fame, he did as much as anyone to make the young sport a national spectacle.

Bryn Athyn, PA · est. 1972

In 1924 aviation pioneer Harold F. Pitcairn established his first flying field on this site, launching decades of experimentation in flight. He and his associates developed the American autogiro—an aircraft with a free-spinning rotor that pointed toward the eventual helicopter—and won the prestigious 1930 Collier Trophy for the achievement. This quiet Montgomery County ground was an early laboratory of American aeronautical innovation.

Altoona, PA · est. 1994

Harold L. Ickes grew up in Altoona before rising to become one of the most consequential figures of the New Deal, serving as Franklin Roosevelt's Secretary of the Interior from 1933 to 1946. He oversaw a vast public-works program that built dams, roads, and public buildings across Depression-era America, all while championing conservation of the nation's natural resources. Blunt and combative, he was also an early and forceful advocate for civil rights within the federal government.

Allentown, PA · est. 1990

Around 1900, the African-American evangelist Harriet A. Baker opened a mission on North Penn Street in Allentown and preached there until her death. Her small storefront ministry took root, and in 1914 it became the first home of St. James A.M.E. Zion Church, which built its permanent home on this spot in 1936. Baker was part of a wider tradition of Black women preachers who founded and sustained congregations at a time when the pulpit was rarely open to them.

Harrisburg, PA · est. 1915

On the banks of the Susquehanna here stood the landing of Harris' Ferry, first granted to John Harris in 1733 and for half a century the name by which the future Harrisburg was known. It was among the most important crossings in early Pennsylvania, funneling settlers, traders, and pack trains westward into the interior and on toward the Ohio Valley. From this modest ferry grew the city that would become the state capital.

Harrisburg, PA · est. 1946

Harrisburg grew from Harris' Ferry, a Susquehanna River crossing established by the trader John Harris Sr. in the early 1700s. His son, John Harris Jr., laid out the town in 1785, and in 1812 it became Pennsylvania's capital. Its position on a major river and travel route made it a hub of trade and government for more than two centuries.

Susquehanna Township, PA · est. 1946

Harrisburg began as Harris' Ferry, a Susquehanna crossing run by the trader John Harris Sr. a century before the town took shape. His son John Harris Jr. laid out the town in 1785, and it became Pennsylvania's capital in 1812. Its riverside setting kept it at the center of travel, trade, and political life for generations.

Swatara Township, PA · est. 1946

What became Harrisburg started as Harris' Ferry, a Susquehanna River crossing established by trader John Harris Sr. in the early 1700s. His son John Harris Jr. laid out the town in 1785, and in 1812 it was chosen as Pennsylvania's capital. Astride a major river and trade corridor, it served as a center of travel and commerce for over two centuries.

Harrisburg, PA · est. 1946

Harrisburg traces its origins to Harris' Ferry, a Susquehanna crossing settled by the trader John Harris Sr. His son John Harris Jr. laid out the town in 1785, and it became Pennsylvania's capital in 1812. For more than two centuries the river city has been a crossroads of travel, trade, and historic events.

Wormleysburg, PA · est. 1947

Harrisburg began as Harris' Ferry, settled in the early 1700s by John Harris Sr. at a strategic crossing of the Susquehanna River. His son laid out the town in 1785, and in 1812 it became Pennsylvania's capital, cementing a role as a crossroads of travel and trade it had already held for generations. For over two centuries the site has funneled people and commerce through the heart of the state.

Harrisburg, PA · est. 1990

Chartered by the Commonwealth and opened in 1845, the Harrisburg Cemetery is the oldest and largest burial ground in Pennsylvania's capital, spreading across 35 acres of carefully composed late-Victorian landscape. Its ornate statuary and its caretaker's house — designed by A.J. Downing, the era's foremost American landscape gardener — reflect the rural-cemetery movement's ideal of the graveyard as a serene, park-like place. More than 30,000 people rest here, among them Revolutionary War soldiers, Pennsylvania governors, and figures of local, state, and national note.

Harrisburg, PA · est. 2005

From around 1900 into the 1950s, the Harrisburg Giants gave the city a place in the golden age of Black baseball. Run for decades by Colonel William Strothers until his death in 1933, the club was one of 27 major Negro League teams and finished second in the Eastern Colored League in 1925. Its rosters glittered with talent — Hall-of-Famer Oscar Charleston among them — and the team played its home games at Island Park through 1957.

Susquehanna Township, PA · est. 1987

When it opened in 1851, this was Pennsylvania's first state mental hospital—a direct result of the tireless campaigning of Dorothea Lynde Dix. Traveling the country to expose the cruel neglect of the mentally ill, Dix pressed legislatures to build humane public asylums, and Pennsylvania answered by placing this one on the wooded hills above Harrisburg.

Lower Merion Township, PA · est. 1947

This early Georgian house went up in 1704, when the Welsh Quaker settlements of the Philadelphia countryside were barely a generation old, and later took its name from owner Richard Harrison. Its most consequential resident arrived in 1774: Charles Thomson, who would serve as Secretary of the Continental Congress through the entire Revolution, keeping the young nation's official records. He lived out his long retirement here until 1824, a founding-era figure quietly farming outside Philadelphia.

Erie, PA · est. 2008

Born in Erie in 1849, Harry Kellar rose to become the "Dean of American Magicians" and the first homegrown conjurer to win international fame. For more than four decades he dazzled audiences across five continents with elegant stage illusions, popularizing the Vanishing Birdcage and perfecting the seemingly impossible levitation. A mentor and friend to the young Harry Houdini, he returned often to perform in the city where his boyhood home once stood.

Erie, PA · est. 2019

Born in Erie, Harry T. Burleigh rose to become one of the most influential figures in American music. A gifted baritone and composer, he studied under Antonín Dvořák and set the verse of poets like Paul Laurence Dunbar and Langston Hughes to song. Above all, Burleigh transformed the spirituals of the enslaved into concert art, championing them as America's only truly original music.

Porter Township, PA · est. 1946

Long before roads crossed these ridges, the Frankstown Path carried Native travelers and colonial traders through the region, passing the spot that became Hart's Log. The name came from a hollow log that the trader John Hart used between 1744 and 1755 as a feeding trough for his pack horses. The little settlement grew from that humble waypoint into the town later called Hartslog, and eventually Alexandria.

Philadelphia, PA · est. 2016

Harvey Pollack, a Temple graduate known to fans as "Super Stat," spent nearly seven decades chronicling professional basketball in Philadelphia. Working with the Warriors and later the 76ers from 1946 to 2014, he invented ways of measuring the game that we now take for granted—counting rebounds, assists, and turnovers—and his annual statistical guide was sought after around the world. In 2002 the Naismith Basketball Hall of Fame honored his lifetime of work.

Harveys Lake, PA · est. 1997

First encountered by frontiersman Benjamin Harvey in 1781, this glacial lake in the mountains above Wilkes-Barre became one of Pennsylvania's grand recreational escapes. By the early 1900s, trains and trolleys delivered crowds to grand hotels like the Oneonta, an amusement park, and public beaches, while Lake Transit Company steamboats ferried thousands across the water. The resort era faded over the twentieth century, but its heyday captured a distinctly American appetite for lakeside leisure.

Hastings, PA · est. 2007

From 1924 to 1926, the United Mine Workers of America brought traveling "Labor Chautauquas"—programs of education and entertainment—to the bituminous coal towns of western Pennsylvania, and Hastings drew the largest crowds in 1925. Under District 2 president John Brophy, these gatherings featured nationally known speakers alongside local performers. They won national press attention and admiration from Progressive-era reformers.

Albany Township, PA · est. 2019

The ridge at Hawk Mountain sits astride a major migration corridor, and for years hunters gathered there to shoot passing raptors by the thousands—a slaughter encouraged by a 1929 bounty on goshawks. In 1934 conservationist Rosalie Edge bought the land and turned the killing ground into the world's first refuge for birds of prey. With early supporters like Richard Pough, she transformed it into a center for raptor research, education, and hawk-watching that draws nature lovers from around the globe.

Philadelphia, PA · est. 1997

Haym Salomon arrived in America around 1772, an immigrant who threw himself into the Revolutionary cause and was twice imprisoned by the British. From Philadelphia he worked as a broker and money-lender, extending enormous credit to help keep the struggling war effort and the young government solvent. Active in the city's Jewish community, he was never repaid and died in debt.

Bethlehem, PA · est. 1953

This 1810 house recalls John Heckewelder, the Moravian missionary who spent decades among Native peoples on the frontier as a preacher, interpreter, and keen observer of their lives. His written works on American Indian languages and customs became important early sources, drawn on by scholars and even by novelists shaping the nation's image of the frontier. In an age of mounting conflict and displacement, Heckewelder tried to bridge two worlds through faith and the written word.

Heidelberg, PA · est. 2012

Opened in 1948, Heidelberg Raceway near Pittsburgh became a lively hub of postwar American entertainment. Its track hosted early NASCAR races that set records and launched local and national drivers to fame, while in 1956 its grounds witnessed the final performance of Ringling Bros. and Barnum & Bailey Circus under the legendary Big Top. Rising costs, new technology, labor troubles, and the pull of television spelled the end for both the circus tent and, by 1973, the raceway itself.

Manheim, PA · est. 1962

Samuel P. Heintzelman was born in this Manheim house in 1805 and rose through the U.S. Army across two of the nineteenth century's defining wars. He earned distinction in the Mexican War of the 1840s and went on to command troops as a Union general in the Civil War. He died in Washington in 1880 and was buried in Buffalo.
