It marks the sixth mile on the southwest side of the original District of Columbia boundary.","why_significant":"The marker shows where the sixth mile of the original District of Columbia boundary fell, six miles from the South Cornerstone at Jones Point. It was the second Virginia stone set at an uneven distance, marked 5 miles 304 poles, because the end of the mile lay in a stream. It also reflects the long stewardship of the Daughters of the American Revolution. It is treated as an exception to the usual relocation rule because it belongs to a rare group of surviving resources.","narrative":"Set in a landscaped median on South Jefferson Street in Bailey's Crossroads, this sandstone marker is one of the stones that outlined the original District of Columbia. It stands at the sixth mile on the southwest side, measured from the South Cornerstone at Jones Point. Because the end of the mile fell in a stream, the stone was placed at 5 miles 304 poles, making it the second Virginia stone set at an uneven distance. Road and apartment construction threatened it, and Arlington County stored it for three years before it was moved to the nearest public land and rededicated in 1965 with a new iron fence. A car struck it in December 1989, and county crews repaired the stone and fence. The marker is valued for its link to the planning of the federal city and for the preservation work of the Daughters of the American Revolution, who dedicated it in 1916.","period_of_significance":"1791-1940","architect_builder":"Unknown","architectural_style":null,"criteria":["A"],"status_note":"Restored to its median location after an automobile accident in December 1989; the white-painted iron fence has some rusting and flaking, and the stone is badly chipped and has been cemented back together more than once.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:01.208366-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/58/6785/41678558/content/electronic-records/rg-079/NPS_VA/91000011.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41678558","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/arlington-county/southwest-no-6-boundary-marker-of-the-original-district-of-columbia-91000011/"}
