The original two-story stone house dates to 1769, with an eastern addition built circa 1820.","why_significant":"The house is argued to illustrate the shift from simple Colonial hall-and-parlor dwellings to more elaborate Federal-period homes. Its first-floor mantels and presses show refined Federal woodwork with reeding and gougework that is unusual in rural vernacular houses. The property is also tied to early settlement and agriculture in Loudoun County.","narrative":"Sleepy Hollow Farm is a stone and frame farmhouse southwest of Leesburg in Loudoun County, Virginia. Its core is a two-story, three-bay stone dwelling built in 1769, dated by an inscribed stone in the south wall, with a hall-and-parlor plan. Around 1820 a one-story stone addition was built to the east, and the interior was updated in the Federal manner. Mantels and built-in presses on the first floor display fluted pilasters, reeding and decorative gougework of a refinement uncommon in rural houses. A frame addition from about 1980 extends to the rear. A stone springhouse that supplies water to the house also contributes to the property, while a guest house and two barns from the late twentieth century do not. The property was listed for its architecture and for its connection to settlement and agriculture, reflecting how a modest early house grew more formal as its owners prospered between 1769 and 1913.","period_of_significance":"1769 - 1913","architect_builder":null,"architectural_style":"Colonial; Early Republic: Federal","criteria":["A","C"],"status_note":"Still used as a single dwelling with a secondary structure; the form states the house retains integrity of materials, workmanship, design, setting and location.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:03.397536-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/13/6816/41681613/content/electronic-records/rg-079/NPS_VA/07000048.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/07000048/b70f3db821-800.webp","url_1600":"https://nationalhistoricalregister.com/media/07000048/b70f3db821-1600.webp","licence":"CC BY-SA 3.0","author":"Jerrye &amp; Roy Klotz, MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:SLEEPY_HOLLOW_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:SLEEPY_HOLLOW_FARM,_LOUDOUN_COUNTY,_VA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41681613","wikipedia":"https://en.wikipedia.org/wiki/Sleepy_Hollow_Farm","wikidata":"https://www.wikidata.org/wiki/Q14713213"},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/loudoun-county/sleepy-hollow-farm-07000048/"}
