The document does not give a clear argument for significance in the readable text.","narrative":"Knoxville Junior High School is a school building in Pittsburgh, Allegheny County, Pennsylvania. It was listed in the National Register of Historic Places in 1987 in the building category. The readable portion of the nomination consists mainly of form headings and blank entries, so the physical description, construction dates, architect or builder, and specific reasons for significance cannot be confirmed from the text. The surviving material indicates the nomination was made under architecture and notes that the building's growth over time is discussed. Further details on its design, alterations, and historical role would require the complete nomination text, which is not legible in this copy.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"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 17:11:33.297783-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/86002673.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/86002673/8825abbb5e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/86002673/8825abbb5e-1600.webp","licence":"CC BY-SA 4.0","author":"Lee Paxton","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:KnoxvilleJuniorHighSchool.jpg\" rel=\"noopener\">Lee Paxton</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:KnoxvilleJuniorHighSchool.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992154","wikipedia":"https://en.wikipedia.org/wiki/Knoxville_Junior_High_School","wikidata":"https://www.wikidata.org/wiki/Q6423675"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/allegheny-county/knoxville-junior-high-school-86002673/"}
