It is also associated with the Quaker Philadelphia Association of Friends, which founded it to educate poor children, and later with the Pennsylvania Society for Promoting the Abolition of Slavery, whose Spring Street Settlement ran social programs there.","narrative":"Built in 1831-34 on Spring Street in Philadelphia, this two and one-half story brick and wood building was constructed by the Philadelphia Association of Friends, a Quaker group that founded the Adelphi School to educate poor children. Classes began in February 1832. The building has a gable roof, a symmetrical facade with a round-headed central door, and 12 over 12 double-hung windows. Its interior is simple, with a center-beam structural system supported by Tuscan wood columns on the first floor. The nomination regards it as an example of vernacular Federal construction that survived well into the 19th century. Its hand-shaped balusters and planed beams combined with milled work show the shift from hand-crafted to machine-made building. It is also probably the last surviving free school building in Philadelphia. From 1908 to 1945 it housed the Spring Street Settlement, which ran classes, clubs and family counseling for Black residents of the city.","period_of_significance":"1831-1834","architect_builder":null,"architectural_style":"Federal (vernacular)","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 17:11:28.989986-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/78002441.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78002441/9ce2655c66-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78002441/9ce2655c66-1600.webp","licence":"CC BY-SA 4.0","author":"Difference engine","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Adelphi_School.jpg\" rel=\"noopener\">Difference engine</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:Adelphi_School.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997274","wikipedia":"https://en.wikipedia.org/wiki/Adelphi_School","wikidata":"https://www.wikidata.org/wiki/Q4682069"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/philadelphia/adelphi-school-78002441/"}
