It is described as the oldest extant public school in the city.","why_significant":"The nomination argues the building is the earliest surviving example of school construction from the first period of Philadelphia public school development, 1818 to 1850. It is said to still show the simple plan and design typical of early city public schools, although its architectural integrity has been compromised by later uses. Areas of significance are given as architecture and education.","narrative":"Built in 1825, the Mifflin School in Philadelphia is recognized as the oldest surviving public school in the city. It dates from the first phase of Philadelphia's public school system, which ran from 1818 to 1850. During that period seven local school boards built forty-nine schools across Philadelphia County. Each of these early schools was small and simple in plan and design, with exteriors that were plain and utilitarian with little architectural decoration. The Mifflin School is regarded as the earliest surviving example of this school construction. Later uses have altered the building, but it still shows the simple plan and design of those early public schools. Its significance is tied to both architecture and education, since it documents how the city first provided public schooling.","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 17:11:34.140177-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/86003308.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/86003308/8922aabc60-800.webp","url_1600":"https://nationalhistoricalregister.com/media/86003308/8922aabc60-1600.webp","licence":"CC BY-SA 2.0","author":"Eli Pousson","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Mifflin_Public_School,_Northern_Liberties.jpg\" rel=\"noopener\">Eli Pousson</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Mifflin_Public_School,_Northern_Liberties.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993751","wikipedia":"https://en.wikipedia.org/wiki/Mifflin_School","wikidata":"https://www.wikidata.org/wiki/Q6844002"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/philadelphia/mifflin-school-86003308/"}
