It also cites the building as one of the earliest and most attractive mansard-roofed buildings in Pennsylvania, and its use as a meeting place for numerous Presidents and, on two occasions, their full cabinets.","narrative":"Built on Broad Street between Chestnut and Walnut Streets, the Union League of Philadelphia was designed by John Fraser and completed in 1865 with John Crump as master builder. The three-story brick and brownstone building in the French Renaissance style has a mansard roof, a granite base, and a portico reached by two curving staircases. Founded in 1862 as a semipolitical Republican club, the League pledged loyalty to the federal government and supported the Union during the Civil War, supplying more than $500,000 and 10,000 troops. In 1908 Horace Trumbauer extended the club to Fifteenth Street, with Indiana limestone walls and a marble hall linking the units. The club hosted numerous Presidents, and on two occasions their full cabinets met there. The building is also noted as one of the earliest and most attractive mansard-roofed buildings in Pennsylvania.","period_of_significance":"1864-1865","architect_builder":"John Fraser (architect, 1864-5); Horace Trumbauer (architect, 1908); John Crump (master builder)","architectural_style":"French Renaissance","criteria":["A","B","C"],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:28.951513-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002331.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002331/4da052cbc4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002331/4da052cbc4-1600.webp","licence":"CC BY 2.5","author":null,"credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:UnionLeauge.JPG\" rel=\"noopener\">Unknown author</a>, <a href=\"https://creativecommons.org/licenses/by/2.5\" rel=\"license noopener\">CC BY 2.5</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:UnionLeauge.JPG"},"district":{"nrhp_refnum":"84003529","name":"Broad Street Historic District (Additional Documentation)","url":"https://nationalhistoricalregister.com/districts/pennsylvania/broad-street-historic-district-additional-documentation-84003529/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997352","wikipedia":"https://en.wikipedia.org/wiki/Union_League_of_Philadelphia","wikidata":"https://www.wikidata.org/wiki/Q16238498"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/philadelphia/union-league-of-philadelphia-79002331/"}
