The house dates to the early nineteenth century and is surrounded by log and frame outbuildings on about 82 acres.","why_significant":"The nomination argues the farm is a noteworthy example of the material folk culture of southwestern Virginia's mountains. It combines Pennsylvania and Tidewater elements with archaic English building practices. The saddlebag house grew in stages from a square cabin, and the springhouse and barn are typical Appalachian forms.","narrative":"Set along a one-lane dirt road in a valley between Chestnut Ridge and Hall Knob, this farm near Blackwell, Virginia, preserves a group of Appalachian log buildings. The main house is a saddlebag type, with two story-and-a-half pens joined by a central limestone rubble chimney. Its western pen, with half-dovetailed corners, was the earliest part, built in the early nineteenth century as a square cabin; a V-notched eastern pen and upper half-story were added later. A country-Federal mantel with fluted Doric pilasters decorates the parlor. Nearby are a round-log springhouse built over a stream and a double-crib hay barn with lean-tos. The Crabtree family probably built the original cabin after buying the land in 1818, and the Blackwell family owned the farm from 1849 to 1923. The complex is valued as clear evidence of mountain folk culture shaped by English, Pennsylvania German and Scotch-Irish building traditions.","period_of_significance":null,"architect_builder":null,"architectural_style":"Vernacular (Appalachian log construction, saddlebag house type)","criteria":[],"status_note":"Listed in excellent condition, unaltered and on its original site; used as a private residence.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:57.337742-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/63/6840/41684063/content/electronic-records/rg-079/NPS_VA/75002041.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/75002041/4586b835a0-800.webp","url_1600":"https://nationalhistoricalregister.com/media/75002041/4586b835a0-1600.webp","licence":"CC BY-SA 3.0","author":"Rutke421 (talk) 00:32, 25 April 2011 (UTC)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Crabtree-Blackwell_farm.JPG\" rel=\"noopener\">Rutke421 (talk) 00:32, 25 April 2011 (UTC)</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Crabtree-Blackwell_farm.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41684063","wikipedia":"https://en.wikipedia.org/wiki/Crabtree%E2%80%93Blackwell_Farm","wikidata":"https://www.wikidata.org/wiki/Q15211914"},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/washington-county/crabtree-blackwell-farm-75002041/"}
