The period of significance runs from circa 1810 to 1956.","narrative":"Temple Hall is a 286-acre farm in the rolling foothills of the Catoctin Mountains in northeastern Loudoun County, Virginia. Its centerpiece is a five-bay, 2½-story Federal-style brick house built around 1810 by William Temple Thomson Mason, set on a small bluff at the end of a tree-lined drive. The house has Flemish bond brickwork, a hipped metal roof, a paneled double door with pilasters and a fanlight, and a 1½-story brick wing to the east. A 1940s renovation by the Symington family added the pedimented portico and steel tie rods to stabilize the building. Nearby stand a brick smokehouse, a converted icehouse, a 19th-century barn and other farm buildings, with open fields around them. The property is significant for architecture and for agriculture. The farm kept working until 1985 and was a leader in crop trends, and the district boundary reflects the farm as it existed from about 1810 through 1956. The property is now a regional park.","period_of_significance":"circa 1810-1956","architect_builder":"William Temple Thompson Mason","architectural_style":"Federal","criteria":["A","C"],"status_note":"Now Temple Hall Farm Regional Park, owned by the Northern Virginia Regional Park Authority; the house and agricultural buildings remain in use, with outdoor recreation added.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:02.778931-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/22/6815/41681522/content/electronic-records/rg-079/NPS_VA/07000053.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/07000053/a4667ebe25-800.webp","url_1600":"https://nationalhistoricalregister.com/media/07000053/a4667ebe25-1600.webp","licence":"CC BY-SA 3.0","author":"Strawser","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Temple_Hall_Mansion.JPG\" rel=\"noopener\">Strawser</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:Temple_Hall_Mansion.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41681522","wikipedia":"https://en.wikipedia.org/wiki/Temple_Hall","wikidata":"https://www.wikidata.org/wiki/Q7698550"},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/loudoun-county/temple-hall-07000053/"}
