The excerpt shows its role in chapter social, scholastic and athletic life from the 1920s through the 1930s. It is the only active Greek chapter house in its immediate area.","narrative":"Alpha Phi's Beta Alpha chapter house stands in the middle of the 500 block of East Armory Avenue in Champaign, just west of the University of Illinois campus. The chapter purchased the property in 1923. The L-shaped building rises two-and-one-half stories and follows the Georgian Revival style, with red brick walls, brick quoins, six-over-six-light double-hung windows, a steeply pitched hip roof and pedimented dormers. A formal south entrance features a round-arched fan transom and molded wood surround. A compatible brick addition was built at the northeast corner in 1950. Inside, the vestibule has stained-glass panels in the sorority's blue and maroon, and the living room has a federal neo-classical mantel. It is the only active Greek chapter house in its immediate area and belongs to a group of fraternity and sorority houses at the Urbana-Champaign campus. Records of the chapter from the 1920s and 1930s describe its members' campus honors, athletics and social events.","period_of_significance":null,"architect_builder":null,"architectural_style":"Georgian Revival","criteria":[],"status_note":"Still an active chapter house, described as the only active Greek chapter house in the immediate area; used for education-related housing.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.307761-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/69/8907/28890769/content/electronic-records/rg-079/NPS_IL/05001250.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/05001250/c83c00c75c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/05001250/c83c00c75c-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Alpha_Phi_uiuc.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Alpha_Phi_uiuc.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28890769","wikipedia":"https://en.wikipedia.org/wiki/Alpha_Phi_Fraternity_House-Beta_Alpha_Chapter_(Champaign,_Illinois)","wikidata":"https://www.wikidata.org/wiki/Q20710393"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/champaign-county/alpha-phi-fraternity-house-beta-alpha-chapter-05001250/"}
