Mason-Dixon Line Crownstone
Kent County, Kent County, Maryland
Marker Inscription
Penn family crest inscribed in east face (slightly weathered), Calvert family crest inscribed in west face (very weathered)
The Story
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.
Why it matters
The Mason-Dixon Line began as a colonial property line but became the most famous boundary in America — the symbolic divide between North and South, and later between free and slave states. A weathered stone in a Maryland field still marks where that idea of a nation split in two was first physically drawn.

Mason-Dixon Crown Marker
Manheim Township, PA
The Mason-Dixon Line began as the peaceful settlement of a long and bitter boundary quarrel between the Penn family of Pennsylvania and the Calverts of Maryland. Between 1763 and 1767 the English surveyors Charles Mason and Jeremiah Dixon ran the line westward with remarkable precision, setting stone markers as they went; at every fifth mile they planted an ornate "crownstone" carved with the coats of arms of the two proprietary families. A crown marker like this one, re-dedicated in 1984, honors that painstaking survey and the famous boundary it fixed across the York County countryside.
Harpers Ferry — John Brown's Raid
Harpers Ferry, WV · est. 1963
Brown and 21 men captured the federal arsenal at the confluence of the Potomac and Shenandoah. Cornered by U.S. Marines under Robert E. Lee, Brown was captured, tried, and hanged — becoming a martyr to abolitionists and a warning to the South.
Grand Army of the Republic Sundial
Baltimore, MD
The Grand Army of the Republic was the great fraternal order of Union veterans who had marched home from the Civil War, and by the 1930s their ranks were thinning fast as the old soldiers passed into memory. This sundial was placed in Baltimore in 1933 not by the veterans themselves but by their descendants — the Daughters of Union Veterans of the Civil War, a heritage society formed to keep faith with the men of 1861–1865. A sundial makes a fitting tribute: a quiet instrument marking the passage of time over a generation that was slipping away.
"To Our Absent Brothers" Memorial
Towson, MD
This monument speaks in the quiet, elegiac language of American memorial tradition, dedicating itself "to our absent brothers" — the comrades who did not return. Such stones were raised across the country in the decades after the nation's wars, when veterans' groups and communities gathered to fix in granite the memory of men lost far from home. Standing in Towson, the Baltimore County seat, the marker turns a public square into a place of remembrance, where a passerby is asked to pause for the missing.
