The document describes the building as a corner house with a 3rd Street facade.","why_significant":"The house is noted mainly for its historic associations: General Thaddeus Kosciuszko and his companion Julian Niemcewicz lived there from November 1797 to May 1798, and Thomas Jefferson visited the General there. The document also cites the cornice, fret moulding and brickwork as fine examples of their type.","narrative":"The corner house at 301 Pine Street in Philadelphia was built in 1775 by Joseph Few, a member of the Carpenter Company and a mason. It was renovated in 1782 under later owner Captain William Alison and was occupied by Joseph Snowden. By 1797 it was operated by Mrs. Anna Relf as a boarding house. General Thaddeus Kosciuszko, who had served as a military engineer during the American Revolution, lived here with his companion Julian Niemcewicz, a notable Polish writer, from November 1797 to May 1798. Thomas Jefferson visited the General here frequently, and the two exchanged political views. Jefferson also helped Kosciuszko draft a will providing for the freedom and education of a group of enslaved Americans. The building's brick Flemish bond, cornice and fret moulding are described as fine examples of their type, and an 1835 insurance survey noted a bake oven in the cellar.","period_of_significance":"1775","architect_builder":"Joseph Few (builder)","architectural_style":null,"criteria":[],"status_note":"Present appearance is described, with stucco removed from three sides except for a one-story addition, and later one-over-one replacement sashes.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.610862-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/70000068.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/70000068/00728fc253-800.webp","url_1600":"https://nationalhistoricalregister.com/media/70000068/00728fc253-1600.webp","licence":"CC BY-SA 4.0","author":"Beyond My Ken","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Thaddeus_Koscuiszko_National_Memorial_301_Pine_Street.jpg\" rel=\"noopener\">Beyond My Ken</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Thaddeus_Koscuiszko_National_Memorial_301_Pine_Street.jpg"},"district":{"nrhp_refnum":"71000065","name":"Society Hill Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/society-hill-historic-district-71000065/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996920","wikipedia":"https://en.wikipedia.org/wiki/Thaddeus_Kosciuszko_National_Memorial","wikidata":"https://www.wikidata.org/wiki/Q2408350"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/philadelphia/thaddeus-kosciuszko-national-memorial-70000068/"}
