It sits on twelve remaining acres with a family cemetery and a small outbuilding.","why_significant":"The house is a good example of a vernacular interpretation of the Greek Revival style, with unusual multi-course American bond brickwork. It is also tied to the Civil War: the farm supplied Confederate troops, and Union soldiers who later occupied it, including as a hospital, wrote names, units, drawings and poems on the attic walls. It also survives as a remnant of Fairfax County's agricultural landscape.","narrative":"Blenheim, also known as Willcoxon Place, is a brick farmhouse built around 1860 on the north side of Old Lee Highway in the City of Fairfax. Once part of more than a thousand acres held by the Willcoxon family, it now occupies twelve acres with a family cemetery and a small shed and pump house. The two-and-a-half-story house follows a Greek Revival, central-passage plan, and its walls use an irregular mix of five- to nine-course American bond that was uncommon for the period. The property is also tied to the Civil War. The Willcoxon farm supplied Confederate troops early in the war, and after the family left, Union soldiers occupied the house and used it as a hospital. Attic plaster walls carry over ninety names, regiment designations, drawings and poems, representing at least fifteen regiments, with the earliest dated writing from March 1862. Most of the surrounding land was sold for housing in the late 1950s.","period_of_significance":"ca. 1860-1865","architect_builder":"Unknown","architectural_style":"Greek Revival","criteria":["A","C"],"status_note":"Historic and current function is single dwelling; the attic wall writings are partly failing from water damage.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:59.484734-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/63/6805/41680563/content/electronic-records/rg-079/NPS_VA/01000152.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/01000152/666c6fa3a4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/01000152/666c6fa3a4-1600.webp","licence":"CC BY 3.0","author":"Aurbanski","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Blenheim_003.jpg\" rel=\"noopener\">Aurbanski</a>, <a href=\"https://creativecommons.org/licenses/by/3.0\" rel=\"license noopener\">CC BY 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Blenheim_003.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41680563","wikipedia":"https://en.wikipedia.org/wiki/Historic_Blenheim","wikidata":"https://www.wikidata.org/wiki/Q5773402"},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/fairfax/blenheim-01000152/"}
