Our namesake

history of the boundary stones

In 1791, Secretary of State Thomas Jefferson instructed Major Andrew Ellicott to survey the ten-square miles that would become Washington, DC. Ellicott and his team placed a series of boundary stones to demarcate the border of the nation’s capital. The boundary stones marked where Washington intersected with the rest of the world and were essential for those attempting to navigate early Washington.
