Northwest No. 3 Boundary Marker of the Original District of Columbia

In 1791, a vision began to materialize along the banks of the Potomac. A new capital city, a beacon of democracy, was taking shape. We stand now before the Northwest No. 3 Boundary Marker of the Original District of Columbia, a silent witness to this ambitious undertaking. The Northwest No. 3 Boundary Marker, one of the original 40 stones, was placed by Andrew Ellicott’s surveying team. This team, which included Benjamin Banneker, meticulously charted the borders of the newly designated “Territory of Columbia.” The Northwest No. 3 Boundary Marker stands as a testament to their efforts, marking not just a physical boundary, but a symbolic one as well. Each stone, spaced approximately one mile apart, was crafted from Aquia Creek sandstone. The side facing the federal territory proudly declares “Jurisdiction of the United States,” while the opposite side denotes “Virginia” or “Maryland.” The Northwest No. 3 Boundary Marker also bears the year of its placement, 1792, and a curious detail: the compass variation at its specific location. This granular level of detail emphasizes the precision and care taken by Ellicott’s team. Sadly, not all the markers have survived the passage of time. Some have been lost to development or damaged by the elements. However, the Northwest No. 3 Boundary Marker persists. It serves as a tangible link to the very beginnings of Washington D.C., a quiet reminder of the dreams and aspirations that shaped this city. The original diamond-shaped district encompassed land from both Maryland and Virginia. The return of Virginia’s portion in 1846 rendered some markers, like this one, reminders of a boundary that no longer exists. Yet, their significance remains. They whisper stories of a nation’s birth and the careful planning that went into creating its capital. They are the quiet sentinels of our history.
