It consists of an original 1897 east building and a larger 1923-1924 west addition designed by Edward Stotz.","why_significant":"The nomination argues the school was the first Pittsburgh high school south of the Monongahela River and one of the city's first few high schools before the 1907 annexation of Allegheny. Its 1897 portion is presented as an example of transitional Classicism in Stotz's work, and the building is linked to education and architecture as areas of significance.","narrative":"Brick high school on an entire city block in Pittsburgh's South Side, made up of an 1897 east building and a larger 1923-1924 west addition, both designed by architect Edward Stotz. The 1897 section is two and a half stories with a hipped slate roof pierced by rounded arch dormers, two-over-two sash windows, and pilasters ornamented with anthemions. The 1924 addition is three stories with a flat roof and an auditorium seating 820. The school was the first Pittsburgh high school south of the Monongahela River and one of the city's earliest high schools. The building is significant for its architecture, showing a transitional Classical style at the turn of the century, and for its role in local education. The school was reorganized several times, including a junior and senior high arrangement from 1924 and a return to four-year status in 1978.","period_of_significance":"1881-1900; 1921-1940","architect_builder":"Edward Stotz (architect); John Siebert (builder)","architectural_style":"Classical Revival","criteria":[],"status_note":"In school use; the document describes it as specializing in vocational training.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.09068-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/86002709.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/86002709/d4b06e03d4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/86002709/d4b06e03d4-1600.webp","licence":"CC BY-SA 4.0","author":"Lee Paxton","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:SouthSideHighSchool.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:SouthSideHighSchool.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992160","wikipedia":"https://en.wikipedia.org/wiki/South_Side_High_School_(Pittsburgh,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q7568479"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/allegheny-county/south-side-high-school-86002709/"}
