Johnston's Confederate headquarters from July to November 1861 and as a hospital after the First and Second Battles of Manassas. It is also one of the few surviving antebellum residences in the Manassas area, representing a local dwelling type. In the 20th century it belonged to the Conner family, who ran one of the county's largest dairy farms.","narrative":"Near Manassas Park, Virginia, this two-story red sandstone house sits on a hill above the Southern Railway tracks. The older section dates to about 1800-1820 and was probably built as an overseer's house; a stone wing added in 1855 changed its plan from side-hall to central-hall. In 1861 the building served as headquarters for General Joseph E. Johnston, commander of the Confederate Army, from July to November, and later as a hospital for the wounded of both Battles of Manassas. A Timothy O'Sullivan photograph of 1862 labeled \"the Yellow Hospital\" has been identified as showing the house. From 1914 to 1973 the Conner family owned it, building a 400-acre dairy farm that shipped milk to Washington. The city of Manassas Park bought the house in 1973. Vacancy and vandalism have badly damaged the interior, but the stone shell survives, and the Manassas Park Woman's Club and other citizens have worked to restore it as a reminder of the area's early history.","period_of_significance":null,"architect_builder":"unknown","architectural_style":null,"criteria":["A","B"],"status_note":"Deteriorated and unoccupied, with interior damaged by vandalism; the roof was repaired in 1978 and local citizens and the city are working on restoration.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:57.465315-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/0/6827/41682700/content/electronic-records/rg-079/NPS_VA/81000645.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/81000645/e488d45940-800.webp","url_1600":"https://nationalhistoricalregister.com/media/81000645/e488d45940-1600.webp","licence":"CC BY-SA 3.0","author":"jweaver28","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Conner_House_2012-09-22_13-13-46.jpg\" rel=\"noopener\">jweaver28</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:Conner_House_2012-09-22_13-13-46.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41682700","wikipedia":"https://en.wikipedia.org/wiki/Conner_House","wikidata":"https://www.wikidata.org/wiki/Q15211515"},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/prince-william-county/conner-house-81000645/"}
