It centers on a stucco-covered stone Federal-style house built in 1797, with outbuildings, fieldstone fences, a cemetery and a garden.","why_significant":"The nomination argues the property is significant under Criterion C for architecture. The 1797 Quaker-plan house retains nearly all of its original woodwork and hardware, showing a transition from Georgian to Federal styles. Later additions and outbuildings document the farm's evolution through about 1950.","narrative":"Rock Hill Farm is a 68.8-acre farm in the rolling northern Virginia piedmont, near Bluemont in Loudoun County. Its main building is a two-story, stucco-covered fieldstone house built in 1797 on a Quaker plan, with a wide hall and two smaller rooms. Additions were made around 1873, 1902, 1947 and 1990, yet the interior keeps nearly all of its original woodwork and door hardware. The hall's paneling and chimneypiece blend Georgian and Federal details. Around the house stand a bank barn, smokehouse, garage, corncrib, dairy and run-in shed from the 1797 and 1873 building phases, along with dry-laid fieldstone fences and the remains of a boxwood garden. A small cemetery from about 1820 holds a marble marker for a fifteen-year-old girl and three fieldstone-marked graves. The farm was listed for its architecture, with a period of significance running from 1797 to about 1950.","period_of_significance":"1797-ca.1950","architect_builder":null,"architectural_style":"Early Republic: Federal","criteria":["C"],"status_note":"Still used as a single dwelling with agricultural outbuildings and a cemetery; the formal garden survives only as remains, and the fieldstone fences are in slight to moderate disrepair.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:03.490952-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/53/6815/41681553/content/electronic-records/rg-079/NPS_VA/09000664.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/09000664/f1ac3edc7a-800.webp","url_1600":"https://nationalhistoricalregister.com/media/09000664/f1ac3edc7a-1600.webp","licence":"CC BY-SA 3.0","author":"Jerrye &amp; Roy Klotz, MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:ROCK_HILL_FARM,_LOUDOUN_COUNTY,_VA.jpg\" rel=\"noopener\">Jerrye &amp;amp; Roy Klotz, MD</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:ROCK_HILL_FARM,_LOUDOUN_COUNTY,_VA.jpg"},"district":{"nrhp_refnum":"11000835","name":"Unison Battlefield Historic District","url":"https://nationalhistoricalregister.com/districts/virginia/unison-battlefield-historic-district-11000835/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41681553","wikipedia":"https://en.wikipedia.org/wiki/Rock_Hill_Farm_(Bluemont,_Virginia)","wikidata":"https://www.wikidata.org/wiki/Q14713149"},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/loudoun-county/rock-hill-farm-09000664/"}
