It was built between 1820 and 1823 as the home of President James Monroe.","why_significant":"Monroe lived at Oak Hill for 22 years, and it was his only home from 1827 to 1830. The mansion was built at the height of his prominence, and the Monroe Doctrine was issued during his last term while he kept his home here. The mansion is also described as the highest development of classical Southern architecture.","narrative":"Oak Hill, near Aldie in Loudoun County, Virginia, is a red brick mansion surrounded by a farm and a group of outbuildings. James Monroe inherited the land from his uncle in 1808 and first lived in a small frame cottage. He built the two-story mansion between 1820 and 1823, after becoming president. Thomas Jefferson may have drawn the plans, and James Hoban, builder of the White House, supervised construction. A main block with a gabled roof is flanked by flat-roofed wings, and a large Roman Doric portico faces south toward the Bull Run Mountains. Other buildings include the cottage, a spring well, a meat house, a horse barn and a blacksmith shop. Monroe made Oak Hill his only home from 1827 until 1830, when he moved to New York. The Monroe Doctrine was announced while he kept his home here, which is the main reason for the property's national importance. The land, about 1,200 acres, is still farmed.","period_of_significance":"1808-1830","architect_builder":"Possibly designed by Thomas Jefferson; construction supervised by James Hoban","architectural_style":"Classical Southern architecture, with a Roman Doric portico","criteria":[],"status_note":"Condition listed as good and altered; a private residence and working farm, with the mansion enlarged in 1923 and restoration efforts made by the owners.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:57.045345-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/83/6790/41679083/content/electronic-records/rg-079/NPS_VA/66000842_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/66000842/c6ac504f98-800.webp","url_1600":"https://nationalhistoricalregister.com/media/66000842/c6ac504f98-1600.webp","licence":"Public domain","author":"Unknown authorUnknown author","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:James_Monroe_Oak_Hill.jpg\" rel=\"noopener\">Unknown authorUnknown author</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:James_Monroe_Oak_Hill.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41679083","wikipedia":"https://en.wikipedia.org/wiki/Oak_Hill_(James_Monroe_house)","wikidata":"https://www.wikidata.org/wiki/Q7073558"},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/loudoun-county/oak-hill-66000842/"}
