Locally nicknamed \"Mud College,\" it served the township's children in grades 1-8 until it closed in 1949. The interior keeps its oak floor, raised teacher's platform, slate blackboard, pot-bellied stove and four rows of ten original wooden desks. A replica belfry was installed in 2001 after the original blew off in a storm. In 1951 a local family bought the building to preserve it, held annual reunions there, and gave it to the township in 2000. It now operates as a living history museum with a program for area students. The school was listed for its role in local education, with a significance period of 1869 to 1962. It is described as the only municipally run original one-room school museum in Adams County.","period_of_significance":"1869-1962","architect_builder":"Unknown","architectural_style":"No style","criteria":["A"],"status_note":"Owned by Mount Joy Township and operated as a living history museum; hosts a program for area students called A Day in the One-Room Schoolhouse.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:59:08.339151-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/12000603.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/12000603/02b9454299-800.webp","url_1600":"https://nationalhistoricalregister.com/media/12000603/02b9454299-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Pleasant_Grove_School_AdamsCo_PA_2.JPG\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Pleasant_Grove_School_AdamsCo_PA_2.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992096","wikipedia":"https://en.wikipedia.org/wiki/Pleasant_Grove_School_(Mt._Joy_Township,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q138006392"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/adams-county/pleasant-grove-school-12000603/"}
