DC Boundary Stones

This boundary stone is unique as it marks one of the original four cornerstones of the District of Columbia. It is located in what is now the neighborhood of Silver Spring, Maryland, near the intersection of East-West Highway and 16th Street. Traditionally enclosed in a protective case or fence, this stone holds a special significance as one of the initial markers from which all other boundary stones were laid out. Its location in a residential and commercial mixed area makes it an easily overlooked but nonetheless significant piece of American history. The stone serves as a historical reminder of the original geometric precision employed in the creation of the nation's capital, anchoring the northern point of the diamond-shaped District.
