Historic Markers in Maryland

Baltimore, MD

In the depths of the long depression that followed the Panic of 1873, railroad companies slashed already-thin wages one time too many, and in July 1877 the anger boiled over. What began among Baltimore and Ohio Railroad workers in Martinsburg, West Virginia, and here in Baltimore quickly leapt from city to city along the rail lines, becoming the first genuinely nationwide strike in American history. For roughly six weeks, freight sat idle, factories fell silent, and clashes between strikers, militia, and federal troops left dozens dead before the movement was suppressed.

Annapolis, MD

Set in Annapolis, Maryland's historic capital, this memorial inscribes the opening words of the First Amendment — the guarantee of religious freedom, free speech, a free press, and the right to peaceably assemble, ratified as part of the Bill of Rights in 1791. The monument honors those who defend those freedoms and stands as a public affirmation of the press's role in American democracy.

Bel Air, MD

This memorial in Bel Air honors the members of Harford County's public safety agencies — police officers, firefighters, and emergency responders — who died in the line of duty while protecting the county's citizens. It stands as the community's collective tribute to those who gave their lives in service to others.

Bel Air, MD

This memorial honors students of Harford County's public schools who entered military service and gave their lives for their country. Behind each name is a young person who left the classrooms of Bel Air and the surrounding county to serve, and did not return. The community placed this tribute so their sacrifice would remain part of the schools' shared memory.

Harford County, MD

This marker recalls the late summer of 1782, when the French army of the Comte de Rochambeau made camp here at Harford Town, then called Bush, on its long march north after the decisive Franco-American victory at Yorktown. Noted as the twenty-second camp of that homeward journey, the site is one link in a chain of encampments that traced the allied army's route across the young nation. The French troops were returning after helping seal the Revolution's outcome the previous autumn.

Baltimore, MD

In mid-twentieth-century Baltimore, tennis was still largely divided along racial lines, and Harvey J. Burns, Jr. (1923–1988) devoted himself to opening the game to Black players in his city. Working as a teacher, promoter, and mentor, he coached young people and helped them find a path into competitive tennis at a time when those doors did not open easily. This memorial marks the legacy of a local pioneer who used sport to widen opportunity.

Carroll County, MD · est. 2016

In 1925, two years after Maryland opened a tuberculosis sanatorium at Henryton, a training school for Black nurses was created to help care for its growing patient population. Revised in 1945 to meet licensing standards, it reopened as the Henryton School of Practical Nursing, gaining a nurses' home in 1952 with labs, lecture rooms, and a library. The school closed in 1963.

Garrett County, MD

In Maryland's mountainous far west, where the Allegheny highlands roll toward West Virginia, this plaque marks the loftiest spot the state's road network reaches — 3,095 feet above sea level in Garrett County. It dates from the era when the Maryland State Roads Commission was knitting the state together with modern paved highways, a decades-long push that turned rutted wagon roads into an engineered system. The named officials and contractor belonged to that generation of road-builders who carried the nationwide 'Good Roads' movement over some of the state's most rugged terrain.

Baltimore County, MD

William Hoffman, a German immigrant who reached Philadelphia in 1768, settled in Maryland in 1775 and became the state's first papermaker, building a clipper paper mill and, in 1781, a gunpowder paper mill. The mills gave rise to a village first called Paper Mills and later Hoffmanville, where Hoffman provided a school, a church, and this family burial ground for his workers. The Hoffman family cemetery preserves the memory of an early American industrialist and the milling community he founded.

Baltimore, MD

Howard A. Kelly helped establish modern gynecologic surgery and was among the first American physicians to use radium to treat cancer. As one of the "Big Four" founding professors of the Johns Hopkins medical faculty, he brought new rigor and inventiveness to the operating room in the era when American medicine was becoming a science.

Baltimore, MD

Judge Hugh Lennox Bond was a Baltimore jurist who stood firmly for the Union and for emancipation during the Civil War era. Later, presiding over federal cases against the Ku Klux Klan, he handed down sentences so severe that he became known as "the curse of the K.K.K."

Dundalk, MD

This memorial honors the infantry — the foot soldiers who bear the hardest, closest burden of war. Standing in Dundalk, Maryland, it gives the community a place to remember those who served in the ranks.

Gaithersburg, MD

On September 11, 2001, coordinated terrorist attacks using four hijacked airliners struck the World Trade Center in New York, the Pentagon just outside Washington, D.C., and a field in Shanksville, Pennsylvania, killing nearly 3,000 people in a single morning. This park in Gaithersburg — in the Maryland suburbs of a capital region that felt the day's shock firsthand — sets aside quiet ground to honor those who were lost. Memorials like it turned countless communities across the country into shared places of mourning and remembrance in the years that followed.

Towson, MD

In 1944, with much of the nation's attention fixed on the Second World War, this ground at Ivy Hill was set aside for a quieter purpose: conservation. The dedication reflects a mid-century American impulse to protect open land, woods, and water from unchecked development — a land ethic that had grown out of the era of national parks and forest reserves and was taking root in private hands and local communities. A simple inscribed stone like this marks the moment a place was promised to the future rather than to the plow or the builder.

Calvert County, MD

On Solomons Island, Joseph C. Lore, Sr. began shipping seafood in 1888 and built this packing house in 1912, launching a business that ran for three generations. Until 1978, the Lore family packed and shipped Patuxent River oysters, crabs, and fish, part of the great Chesapeake seafood economy that fed much of the nation. The weathered building recalls the watermen, tongers, and shuckers whose labor moved the bay's bounty to market.

Baltimore, MD

Jacob Epstein built a great wholesale business supplying merchants across the American South and used his fortune as a collector of Old Master paintings and a generous philanthropist. He was among the early champions of matching charitable grants, a method that multiplied the impact of giving.

Baltimore, MD

Jesse Lazear was a young physician who joined the U.S. effort to understand yellow fever, a disease that had terrorized American cities for generations. To test the theory that mosquitoes carried the illness, he allowed himself to be bitten by infected insects—and died of the fever, confirming how it spread. His sacrifice helped make possible the mosquito-control campaigns that later saved countless lives.

Baltimore, MD

John Jacob Abel was a trailblazing pharmacologist whose research advanced the understanding of adrenalin, insulin, and the artificial kidney. Often called a father of American pharmacology, he pursued the chemistry of the body at Johns Hopkins in the early twentieth century. His work opened paths that later saved countless lives.

Baltimore, MD

This bridge was erected by the City of Baltimore in 1926, its plaque naming the mayor, engineers, and contractors who brought it into being during a decade of rapid municipal growth. Across 1920s America, cities were pouring concrete and steel into new roads and bridges to keep pace with the automobile age, and dedication plaques like this one recorded the public officials and firms responsible.

Prince George's County, MD

This Latin inscription marks the spot in the Maryland countryside where Pierre (Peter) Charles L'Enfant lay for more than eighty years. A French-born military engineer who volunteered for the Continental Army during the Revolution, L'Enfant went on to draw the sweeping grand plan for the new federal capital on the Potomac — the radiating avenues and ceremonial vistas that still shape Washington, D.C. He died in obscurity and near-poverty in 1825 and was buried on a private estate here in Prince George's County. As the inscription records, in 1909 a grateful nation finally reinterred his remains with honor at Arlington National Cemetery, leaving this cenotaph to mark his first resting place.

Harford County, MD

The oldest part of this house went up around 1747, when Henry Scarff settled a Maryland farm and raised a modest four-room dwelling; generations of his descendants enlarged it, adding the tall central block by 1849. In 1929 Harvey S. Ladew, a wealthy sportsman and self-taught gardener, bought the old Scarff place—then called Pleasant Valley Farm—and set about transforming its grounds into one of America's most celebrated topiary gardens, sculpting hedges and yews into fanciful shapes still admired today.

Worcester County, MD

The U.S. Life-Saving Service built the North Beach Station on this stretch of the Maryland coast in 1884, part of a national chain of stations whose surfmen patrolled the shore and rowed open boats into the surf to rescue shipwrecked crews. When the Life-Saving Service merged into the new U.S. Coast Guard, the station carried on its lifesaving work until it was decommissioned in 1952; the building itself was lost to fire in 1962.

Towson, MD

These stone abutments once carried the York Road bridge of the Maryland & Pennsylvania Railroad—affectionately nicknamed the 'Ma & Pa.' The overpass was rebuilt in 1900 by the Baltimore & Lehigh Railroad, an upgrade from an earlier narrow-gauge crossing on this winding line north of Baltimore.

Towson, MD · est. 1999

These stone abutments once carried a plate-girder bridge over York Road for the Maryland & Pennsylvania Railroad—the beloved 'Ma and Pa.' Rebuilt in 1900 from an earlier narrow-gauge line, the railroad wound a circuitous 77-mile course between Baltimore and York, Pennsylvania, before being abandoned in 1958 as traffic dwindled and its bridges decayed. The overpass came down in 1959, leaving only these abutments.

Bethesda, MD

This is one of twelve identical "Madonna of the Trail" monuments the Daughters of the American Revolution placed across the country in 1928 and 1929, each a stern pioneer mother in bonnet and shawl striding westward with a child at her side. The DAR raised them to honor the women of the covered-wagon generation and to mark the National Old Trails Road, a coast-to-coast auto route that stitched together older paths of American expansion. As the inscription notes, this ground carried far older traffic too: in the spring of 1755 General Edward Braddock led his ill-fated British and colonial army along this corridor toward Fort Duquesne, in the opening campaign of the French and Indian War.

Frederick County, MD

On July 9, 1864, the fields along the Monocacy River south of Frederick became the stage for a desperate delaying action in the Civil War's final year. Confederate General Jubal Early, driving north through Maryland toward a lightly defended Washington, D.C., collided with a badly outnumbered Union force under General Lew Wallace. Wallace lost the battle but won the day that mattered: the hours his men bought held Early up just long enough for veteran reinforcements to reach the capital's forts before he did.

Towson, MD

This memorial in Towson honors the troopers of the Maryland State Police who gave their lives in the line of duty. Maryland organized a statewide police force in the early 1920s, part of a nationwide move to professionalize law enforcement for the automobile age. Rather than marking a single loss, the monument holds the collective memory of generations of officers who did not return home.

College Park, MD · est. 2006

In 1914 the University of Maryland donated this College Park land for Maryland's first state tree nursery, where state forester Fred W. Besley — a student of forestry pioneer Gifford Pinchot — and head nurseryman Silas Sines Sr. pioneered large-scale tree propagation. Thousands of seedlings grown here reforested Maryland's woodlands and roadsides, healing land ravaged by decades of heavy logging and farming.

Carroll County, MD · est. 1970

Between 1763 and 1767, English astronomers Charles Mason and Jeremiah Dixon surveyed the disputed boundary between Pennsylvania and Maryland, using precise celestial observations to settle a long-running colonial quarrel. This particular stretch was run in late July and early August of 1765. Their meticulous line became one of the most famous borders in America.

Harford County, MD · est. 1970

From 1763 to 1767, Charles Mason and Jeremiah Dixon carried their astronomical survey across the countryside to fix the boundary between Pennsylvania and Maryland and end the provinces' border disputes. This section of the line was surveyed on June 26, 1765. The exacting work stands as a landmark of eighteenth-century science applied to the shaping of colonial America.

Kent County, MD

This is a crownstone — one of the ornate boundary markers set along the Mason-Dixon Line, the border that surveyors Charles Mason and Jeremiah Dixon painstakingly ran between 1763 and 1767 to settle a bitter, decades-long dispute between two proprietary families. The heraldic crests carved into its faces name those families: the Penns of Pennsylvania looking east, the Calverts of Maryland looking west. Unlike the plainer mileposts, crownstones like this one were imported from England and placed every five miles, each a small monument to a border drawn with astronomical precision through colonial wilderness.

Baltimore, MD

Set within Druid Hill Park—one of America's oldest large municipal parks, laid out in 1860—these stone pillars mark the entrance to a Memorial Grove, a stand of oaks planted as a living tribute to those who served and sacrificed. Memorial groves like this one reflect an early 20th-century American tradition of honoring the fallen not with stone alone but with trees meant to grow and endure across generations. The grove turns a quiet corner of a beloved city park into a place of remembrance.

Charles County, MD

On a small island in the Potomac in December 1900, Reginald Fessenden and his assistant Frank Very did something no one had done before: they sent understandable human speech through the air on radio waves, from one tall mast to another. Until that moment wireless meant only the dots and dashes of Morse code; here, the spoken word itself first traveled without wires. It was the quiet beginning of everything from broadcast radio to the mobile phone.

Garrett County, MD · est. 1947

The National Road was the nation's first federally funded highway, championed by Treasury Secretary Albert Gallatin as a link binding the young country to its western territories. Construction began at Cumberland, Maryland, in 1811 and reached Wheeling on the Ohio by 1818, carrying settlers, freight, and mail deep into the interior. After 1835 the states ran it as a toll road for seventy years, and in the automobile age it was rebuilt as U.S. Route 40.

Chevy Chase, MD

In 1774, on the eve of the Revolution, Thomas Johns—soon to serve as a colonel in the Continental cause—joined Georgetown merchant Thomas Richardson to raise flour mills along the reliable current of Rock Creek. Grinding grain into flour for the growing capital region, mills operated on this site for roughly a century, outlasting the men who built them and falling silent only in the 1870s. In an age before steam, a dependable creek was industrial infrastructure, and Rock Creek's waters turned the stones that fed Georgetown's wharves and tables.

Dundalk, MD

In the late summer of 1814, fresh from burning Washington, a British army pushed toward Baltimore, the young nation's third-largest city and a nest of the privateers that had harried British shipping. On September 12, Maryland militia under General John Stricker met the advancing column here at North Point, and in the opening skirmishing the British commander, General Robert Ross, was mortally wounded. The militia's stubborn delaying action bought precious hours for Baltimore's main defenses to prepare.

Towson, MD

Built in 1759 by Charles Ridgely the Elder and two of his sons, this iron foundry ran for some seventy years along a spring branch near Baltimore, part of the Ridgely family's sprawling Hampton estate. Colonial Maryland's iron industry met a growing demand for tools, implements, and hardware, turning local ore, charcoal, and water power into finished iron. The works spanned the late colonial era into the decades of the early republic.

Harford County, MD

In the young republic's earliest years, the newly organized Methodist Episcopal Church set out to plant education alongside faith, and in 1785 its founding bishops opened Cokesbury College at Abingdon, Maryland — named for the two men who led it. Championed as the first Methodist college in the world, the school rose on the old post road that had carried travelers and mail through Harford County since the 1600s. Its life was brief: a decade after opening, fire consumed the building in December 1795, and the ambitious experiment ended in ashes 175 yards east of where this marker stands.

Baltimore, MD

This walk of flowering redbuds honors Wally Orlinsky, a Baltimore civic leader who channeled his later career into greening Maryland's public spaces. He founded Tree-Mendous Maryland, a state program that rallied ordinary citizens to plant and care for trees across parks, streets, and schoolyards. Dedicated in April 2002, the memorial turns a living stand of native trees into a tribute — a fitting memorial for a man whose signature cause was putting more of them in the ground.

Frederick County, MD · est. 1948

This border marker salutes Pennsylvania, chartered to William Penn in 1681 as a Quaker 'holy experiment' founded on religious tolerance and fair dealing. Penn's colony grew into one of the most prosperous and diverse in British America, its capital of Philadelphia becoming the beating heart of the Revolution. There the Declaration of Independence was adopted in 1776 and the Constitution framed in 1787 — the two documents that gave the United States its birth and its enduring form.

Frederick County, MD

On July 9, 1864, the fields along the Monocacy River in Frederick County became the site of a desperate delaying action as a Union force under General Lew Wallace met Confederate General Jubal Early's army marching north toward Washington. Outnumbered, the defenders — including the Pennsylvania regiments this monument honors — were pushed from the field, but the hours they cost Early proved decisive. That single day's delay let Union reinforcements reach the capital's defenses before the Confederates arrived, earning Monocacy its name as 'the Battle That Saved Washington.'

Baltimore County, MD

Half a mile north of Monkton, Pleasant Valley grew up in the mid-19th century as a railroad settlement built around mining iron ore and soapstone, its ore feeding the nearby Ashland Iron Furnace. Named in Civil War records of 1864 and mapped in the 1877 Hopkins Atlas, it grew into a compact village with a station, houses, a tavern, and a hotel wryly called the 'Rat Trap.' When the ore and soapstone veins gave out in the 1890s, the town was dropped from train schedules and swiftly vanished; only crumbling foundations remain along the NCR Trail today.

Washington County, MD

This granite infantryman—known affectionately as "Old Simon"—stands watch over Antietam National Cemetery near Sharpsburg, Maryland, where thousands of Union dead from the Battle of Antietam are buried. On September 17, 1862, the fighting here became the bloodiest single day in American history, with more than 22,000 men killed, wounded, or missing. Dedicated in 1880, the towering figure of a common private at parade rest was meant to honor not the generals but the ordinary soldiers who filled the ranks. The cemetery grew out of the battle's staggering toll, gathering the fallen from the surrounding fields into ground set aside for their rest.

Columbia, MD

Patapsco Valley State Park is one of Maryland's oldest state parks, tracing its origins to the early 1900s conservation movement that set aside the wooded gorges of the Patapsco River for public use. Protecting such places is quiet, unglamorous work, and it falls to state rangers to safeguard both the land and the historic mills, bridges, and railroad traces scattered through the valley. This memorial marks the death of Maryland ranger Joseph Allen Carr, who was killed in the line of duty on April 13, 1978, while carrying out that charge.

Baltimore, MD

This memorial gathers the recollections of those who endured the Second World War, among them the landings at Omaha Beach on June 6, 1944 — D-Day. On that stretch of Normandy sand, American troops pushed through murderous fire to establish the beachhead that opened the liberation of Western Europe. The inscription speaks in the voice of a veteran returning to honor the men who fell there.

Baltimore, MD

In neighborhoods like Baltimore's Remington and Wyman Park, the Second World War touched nearly every household. As young men and women left their rowhouse blocks for battlefields, ships, and factories across the globe, communities gathered to honor the local sons and daughters who answered the call between 1941 and 1945. This memorial reflects the wave of neighborhood tributes raised across America in the war's aftermath, insisting that the sacrifice of ordinary people from ordinary streets be remembered.

Baltimore, MD

This cannon marks Rodgers Bastion, a key point in the chain of earthworks that ringed Baltimore against British attack in September 1814. Manned in part by sailors under Commodore John Rodgers, the fortifications formed part of a defensive line of some 12,000 men and 100 guns commanded by General Samuel Smith. The marker was placed in 1914 to mark the centennial of the city's defense.

Harford County, MD

In the rolling farmland of Harford County stands a church whose roots reach back to the Jesuit missionaries who kept the Catholic faith alive in Maryland — a colony founded as a rare haven of religious tolerance in early America. Completed in 1792 by Father Sylvester Boarman, a Jesuit tending the nearby mission of St. Joseph at Priest's Ford, Saint Ignatius rose in the first years of the new republic, when Catholics were only beginning to worship freely and openly. It is remembered as the oldest Roman Catholic church in continuous use in the Archdiocese of Baltimore, the founding see of American Catholicism. Its early pastors even ministered to the family of Charles Carroll, the Maryland statesman whose name is woven through the nation's founding.

Glen Burnie, MD

This Maryland Historical marker commemorates 'Shipley's Choice,' a colonial land tract tied to Adam Shipley, who arrived in Anne Arundel County in 1668 and patented 200 acres along the South River in 1681. It was dedicated in 1968 during a tercentenary celebration of the Shipley family in Maryland. The name preserves the practice by which English settlers claimed and named their patented ground in the young Chesapeake colony.

Baltimore, MD

In the years after the Civil War, Sidney Lanier earned a national reputation as a poet and flutist while helping shape the intellectual life of the new Johns Hopkins University, where he became its first writer-in-residence. Known as "the sweet singer of the South," he also taught in Baltimore and retold Arthurian legend for young readers in The Boys' King Arthur. He died young, at 39, but left a lasting mark on American letters.

Harford County, MD

This handsome brick house rose in 1768, in the last decade before the Revolution, on a Harford County tract said to have been a colonial father's gift — a dowry — to his daughter Sophia. The estate passed down through the women it was named for and tied the family to some of early America's notable figures, including Bishop William White of Philadelphia and a daughter who married the Revolutionary financier Robert Morris. It survives as one of Maryland's fine pre-Revolutionary Georgian dwellings.

Prince George's County, MD

This weathered sandstone post is one of the original boundary stones that marked the ten-mile-square District of Columbia, set out beginning in 1791 to define the young nation's new federal capital. Surveyor Andrew Ellicott and free Black astronomer Benjamin Banneker laid out the perfect diamond straddling the Potomac, and every mile a stone like this was planted, its faces carved to name the jurisdiction and the mile count from the starting corner at Jones Point. As the marker on the district's southeast leg, 'Miles 5' recorded the distance walked along the line, a small monument to one of America's earliest great feats of public surveying.

Dundalk, MD

Rising on the tidewater east of Baltimore, the Sparrows Point works grew from an 1880s Pennsylvania Steel venture into the sprawling core of Bethlehem Steel's empire — for a time the largest steel mill on Earth. Its furnaces and shipways turned out the steel and vessels that armed and supplied the nation through both World Wars, and a whole company town grew up around the jobs it created.

Hampstead, MD

Long before Hampstead had a name, a footpath threaded these hills, linking the Patapsco country around Baltimore to Letort's Spring near Carlisle. The frontier scout Christopher Gist charted that Indian trail, and by 1738 it had been widened into a public road carrying settlers and goods across the Maryland backcountry. In 1786, on a tract poetically called Spring Garden, Christopher Vaughn platted the town of Hampstead astride that very route — a young community taking root in the first decade of American independence.

Baltimore County, MD

St. John's Parish was one of the original Anglican parishes carved out of colonial Maryland in 1692, when the colony formally established the Church of England. Its first house of worship stood at Joppa Town, then a bustling tobacco port and county seat on the Gunpowder River; when Baltimore eclipsed Joppa and the town slid into ruin, the congregation needed a new home. Edward Day paid to build the church that stands here, consecrated in 1817 to carry the old parish forward into a new century.

Harford County, MD

This monument gathers up Maryland's outsized place in the nation's founding, when the little capital at Annapolis briefly held the eyes of a new country. There, in December 1783, George Washington laid down his military commission and returned power to civilian hands — one of the young republic's defining acts — and the Confederation Congress, meeting in the same statehouse, closed the books on the Revolution. In the years that followed Maryland ceded the land that became the District of Columbia, and a Maryland lawyer named Francis Scott Key would give the country the words of its national anthem.

Anne Arundel County, MD

This monument marks one hundred years of the United States Navy's submarine service, a force that began at the dawn of the twentieth century when the Navy acquired its first commissioned submarine and grew into one of the most demanding and secretive branches of American sea power. From primitive early boats to the nuclear fleet of the Cold War and after, submariners have carried out their duty largely unseen, enduring cramped quarters, crushing depths, and long silent patrols. Standing in Maryland near the heart of Navy tradition, the memorial deliberately widens its dedication beyond the sailors themselves to the families who wait ashore and the support personnel who keep the boats at sea.

Bethesda, MD

This anchor, taken from a Coast Guard cutter, once stood before the Staten Island Marine Hospital—the very place where, in 1887, the Hygienic Laboratory was founded to study disease among arriving immigrants and sailors. From that single laboratory room grew the National Institutes of Health, today the largest biomedical research enterprise in the world.

Baltimore, MD

In the maritime heart of Baltimore lies the small burial ground of the Fell family, the English settlers who gave their name to Fell's Point. Arriving in the eighteenth century, the Fells laid out a shipbuilding and shipping community along the deep water of the Patapsco River, and their surname still marks one of the city's oldest and most storied neighborhoods. This family plot is a quiet reminder that a bustling seafaring district began with a single household's land and ambitions.

Bel Air, MD

The Hays House was built in 1788, in the first years after American independence, making it one of the oldest buildings in Bel Air, Maryland. Around 1814 it was enlarged by Thomas A. Hays, a local attorney, landowner, and entrepreneur whose family helped shape the young county seat. Moved to its present location in 1960, the house still keeps its original interior woodwork and weatherboard, a rare survival of early federal-era craftsmanship.
