Benjamin Banneker: SW 9 Intermediate Boundary Stone, also known as an Intermediate Stone of the District of Columbia, is a surveyors' boundary marker stone. It is a one foot square sandstone block, extending about 18 inches above ground and probably about 2 feet below ground.[3]

The stone is one of 40 boundary markers of the original District of Columbia. It presently marks the boundary between the City of Falls Church and Arlington County, Virginia. It is within Arlington County's Benjamin Banneker Park.[4]

It was named and was declared a National Historic Landmark in 1976 at the instigation of the Afro-American Bicentennial Corporation.[2][3][5] The stone was the first of the District of Columbia boundary markers to be listed on the National Register of Historic Places.

Perhaps only by its naming in 1976, it is associated with the life of Benjamin Banneker, (1731-1806), an African American surveyor, mathematician and astronomer who assisted Andrew Ellicott during the first two months of Ellicott's 1791-1792 survey of the boundaries of the original District of Columbia.[6][7]
