Martha Washington joined him there on February 10 and stayed until June 8, 1778, just before the Continental Army left Valley Forge on June 19. The house has a plain Early Georgian exterior of cut graystone, with two chimneys, a three-bay west facade, and a Dutch door sheltered by a small domed hood. Its interior has a central side hall, two rooms on each floor, and Georgian paneling of advanced design, wide fireplaces, and wrought iron hardware. About 90 percent of the house is original. It is regarded as an excellent example of a small colonial farmhouse, and it is now restored, furnished with Washington mementos, and open to visitors.","period_of_significance":"December 1777-June 1778","architect_builder":null,"architectural_style":"Early Georgian exterior with Late Georgian interiors","criteria":["B","C"],"status_note":"Carefully restored, furnished with Washington mementos, and open to visitors as a historic house exhibit","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.68969-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/73001655_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/73001655/c08dd64ce5-800.webp","url_1600":"https://nationalhistoricalregister.com/media/73001655/c08dd64ce5-1600.webp","licence":"CC BY-SA 3.0","author":"JC1008 Credit Photo to: RevolutionaryPA.com","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Washington%27s_Headquarters_Valley_Forge.jpg\" rel=\"noopener\">JC1008 Credit Photo to: RevolutionaryPA.com</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:Washington%27s_Headquarters_Valley_Forge.jpg"},"district":{"nrhp_refnum":"66000657","name":"Valley Forge National Historical Park","url":"https://nationalhistoricalregister.com/districts/pennsylvania/valley-forge-national-historical-park-66000657/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994425","wikipedia":"https://en.wikipedia.org/wiki/Washington%27s_Headquarters_(Valley_Forge)","wikidata":"https://www.wikidata.org/wiki/Q12072536"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/montgomery-county/washingtons-headquarters-73001655/"}
