The boundary was set by Miles Standish and others as a committee from the Plymouth Colony.

The stone stands about 28 inches high, 12 inches wide and 7 inches thick, in a residential setting. Its face carries a B on the east side of a horizontal line and an S on the west side. Both towns were established in 1639 and have kept a relatively stable boundary, although several adjustments have been made over time. The boundary was established by Miles Standish and others serving as a committee from the Plymouth Colony. The date the post itself was erected is unknown, and no maker is recorded. It was listed for its association with the history of how Barnstable's boundary was set, and it is considered to retain its location, design, materials, workmanship, setting and feeling. Vehicles and vandalism were noted as threats to the marker.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":["A"],"status_note":"Described as unaltered and in a residential setting; endangered by vehicles and vandalism.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:01.748638-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/85/7891/63789185/content/electronic-records/rg-079/NPS_MA/87000269.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63789185","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/barnstable-county/town-boundary-marker-87000269/"}
