It is the second mile marker on the northwest leg of the original District of Columbia boundary, set within a small wrought iron fence.","why_significant":"The marker is significant because it marked the second mile on the northwest side of the District of Columbia, two miles from the West Cornerstone. It is part of the group of boundary markers tied to the development of the federal city. The nomination also notes that the words \"of the\" appear in italics here for the first time and continue in italics on later stones.","narrative":"Set in the rear yard of a private property in Arlington, Virginia, this Aquia sandstone marker is the second mile stone along the northwest leg of the original District of Columbia boundary. It sits about 165 feet northwest of the house, near the crest of a hill overlooking Old Dominion Drive, and is only slightly visible from the road. The stone is chipped and worn, its top is gone, and pieces were once carried off for use as whetstones, as noted in an 1894-97 survey. Only part of the original inscription remains on the southeast face. A wrought iron fence about three feet square surrounds it, along with a bronze plaque placed in 1969 by patriotic societies. The marker is significant because it fixed the second mile on the northwest side, two miles from the West Cornerstone, tying it to the layout of the federal city. It is also the first stone where the words \"of the\" appear in italics.","period_of_significance":"1791-1940","architect_builder":null,"architectural_style":null,"criteria":["A"],"status_note":"The stone is chipped and in poor condition with its top worn away, and the original inscription is only partly visible on the southeast side. The wrought iron fence is painted blue, with some flaking paint and rust at the base of the rails.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:00.931176-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/52/6785/41678552/content/electronic-records/rg-079/NPS_VA/91000004.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41678552","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/arlington-county/northwest-no-2-boundary-marker-of-the-original-district-of-columbia-91000004/"}
