The original portion dates to the mid-eighteenth century.","why_significant":"The house is associated with the Revolutionary War, when General Henry Knox and Captain Alexander Hamilton are said to have been quartered there during the ten days before the Battle of Trenton in December 1776. It is also tied to the Chapman family, early settlers of the Wrightstown area, and its architecture is regarded as highly rated among neighboring Revolutionary-period houses.","narrative":"Built of coursed fieldstone in southeastern Pennsylvania, this farmhouse in Upper Makefield Township was constructed in three sections, with the earliest portion dating to the mid-eighteenth century. An addition before the end of the eighteenth century doubled the size of the larger section. Its shingle gable roof, box cornice and two brick chimneys remain, along with original interior features such as wide planked floors, a chair rail, a batten door and a fireplace with bake oven in the east end. During the ten days before the Battle of Trenton in December 1776, the house served as headquarters for General Henry Knox and Captain Alexander Hamilton, who are said to have stayed in the east section. Dr. John Chapman, who owned the house during the Revolution, descended from one of the first white settlers north of Newtown. Its eighteenth-century setting has changed little, and it is regarded as one of the more notable Revolutionary-period houses in the area.","period_of_significance":"1745","architect_builder":null,"architectural_style":null,"criteria":["A","B"],"status_note":"The document states the house is still standing with some additions and structural changes.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.16967-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/74001757.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/74001757/1d0336528b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/74001757/1d0336528b-1600.webp","licence":"CC BY-SA 3.0","author":"Shuvaev","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:London_Purchase_Farmhouse_PA_01.JPG\" rel=\"noopener\">Shuvaev</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:London_Purchase_Farmhouse_PA_01.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996722","wikipedia":"https://en.wikipedia.org/wiki/London_Purchase_Farm","wikidata":"https://www.wikidata.org/wiki/Q6670682"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bucks-county/chapman-john-house-74001757/"}
