D.C. Boundary Stone NE No. 1

Silver Spring, Montgomery County, Maryland

Marker Inscription

This plaque marks the site of the District of Columbia north-east boundary stone no. 1 originally placed here 1791-1792

Erected by Daughters of the American Revolution

The Story

This plaque marks the spot where one of the original boundary stones of the District of Columbia was set in 1791–1792. The stones were placed at intervals to mark out the ten-mile-square federal district for the new national capital. Together they form some of the earliest federal monuments in the country.

Why it matters

The boundary stones physically laid out the young republic's capital, a foundational act in creating the seat of the American federal government.

The story behind this marker

AI context

The era

In the early 1790s, the United States was a brand-new nation deciding where its permanent capital should stand. The choice fell on a diamond-shaped tract of land along the Potomac, a fresh federal district carved out to be the seat of government, independent of any single state.

Before any grand buildings could rise, the district itself had to be defined on the ground. That meant surveying and physically marking the borders of a square measuring ten miles on each side, a precise geometric shape laid over farmland, forest, and riverbank.

To do that, surveyors set boundary stones at regular intervals around the perimeter, one for roughly every mile. Placed in 1791 and 1792, these were among the very first monuments the federal government ever established.

People & events

The stone remembered here was the first of the northeast boundary markers, part of that original ring set to define the new District of Columbia. Each stone was a small but deliberate act of nation-building, turning an idea drawn on a map into a fixed line on the earth.

The survey that placed them was a serious feat of early American science and craftsmanship, requiring careful astronomical observation and measurement to get the great square right. The team that carried it out worked through difficult country to plant each marker in its proper place.

Over the centuries, the city grew far beyond these humble stones, and many of the originals were lost, damaged, or forgotten. To keep the memory of this one alive, the Daughters of the American Revolution placed this plaque to mark the site where boundary stone number one was first set.

Its place in the American story

The boundary stones are among the oldest federal monuments in the country, older than most of the famous buildings of the capital they helped define. They represent the literal groundwork of the seat of American government.

They also tell a very American story: that a republic, before it can build its monuments and institutions, must first agree on a place and mark its edges. These modest stones did exactly that, laying out the ground on which the national capital would rise.

Because so many have been damaged or lost over more than two centuries, each surviving stone or marked site has become a small treasure, a direct physical link back to the founding era and the deliberate creation of the federal district.

If you visit

Do not expect a towering monument here; the reward of this site is in what it represents rather than its size. A boundary stone is a humble object, and finding one asks you to slow down and appreciate a quiet piece of history hiding in an everyday landscape.

Stand at the spot and consider that you are at a corner of the original survey that defined the nation's capital, a line drawn in the earliest years of the republic. The plaque is your invitation to picture the surveyors at work here in the early 1790s.

It makes a rewarding stop for anyone tracing the founding history of Washington and its surroundings. Seek it out the way collectors seek the boundary stones as a set, and you will see the edges of the capital in a way most visitors never do.

Alexander Graham Bell

Washington, DC · est. 1947

On June 3, 1880, Alexander Graham Bell transmitted speech through the air on a beam of light—not a wire—using his newly invented 'photophone,' sending a wireless voice message from the top of this building to a receiver blocks away. Bell considered the photophone among his most important inventions, though the world was not yet ready to use light for communication. The plaque was placed in 1947 to mark the centennial of his birth.

Newport Mills

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.

Maryland's First State Tree Nursery

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.

The Mayflower Hotel

Washington, DC

The Mayflower Hotel opened in 1925 on Connecticut Avenue and immediately became a hub of Washington's political and social life, hosting Calvin Coolidge's inaugural ball as its first major event. Over the decades it entertained every president who followed and served as an in-town residence for vice presidents, cabinet members, Supreme Court justices, and members of Congress. Its Beaux-Arts grandeur earned it a place on the National Register of Historic Places.
