Did you know

  • The marker was placed in 1791 as part of the initial survey of the District of Columbia.
  • The survey team was led by Andrew Ellicott and included the noted mathematician and astronomer Benjamin Banneker.
  • There were originally forty such markers placed at one-mile intervals along the perimeter of the District.

History

In 1790, the Residence Act authorized the creation of a federal district along the Potomac River. To define the borders, President George Washington commissioned a survey to mark a ten-mile-square area. Andrew Ellicott was appointed to lead the survey, assisted by Benjamin Banneker. The Southwest Number 1 Boundary Marker, placed in 1791, represents the starting point of this monumental task. These markers were intended to permanently establish the legal boundaries of the District of Columbia, serving as physical evidence of the federal government's territorial claims at the time of the nation's founding.

Cultural significance

The marker serves as a testament to the early scientific and political collaboration in the United States. Its placement acknowledges the contributions of Benjamin Banneker, a free African American scientist, whose involvement in the survey remains a point of historical pride and study. Beyond its function as a border demarcation, the site functions as a cultural touchstone for understanding the administrative origins of Washington, D.C. It represents the intersection of 18th-century surveying technology, federal governance, and the foundational history of the American capital.

Geography and landscape

The marker is situated in a location that was part of the original 1791 survey line. Historically, this area was characterized by the rural terrain of the Potomac region, though it has since been integrated into the modern urban landscape of the District of Columbia. The monument itself is typically found protected by a metal enclosure, standing as a solitary point of historical interest amidst the surrounding local infrastructure. Its specific placement on the boundary line reflects the precise geometric intent of the original survey.
