It was built by the County in 1818 and includes an 1880 cell block within its original yard.","why_significant":"The nomination argues the jail is one of the oldest penal institutions in the country to have been used continually. It has undergone few modernizations, and the document says it would make a well-suited museum of penal history. The building also represents the persistence of Georgian plan traditions in Central Pennsylvania rather than the Greek Revival style seen farther north.","narrative":"Built by Franklin County in 1818 on King Street in Chambersburg, the jail is a two-story building with a hipped roof and central cupola, with walls over three feet thick. Its front contains a central doorway flanked by cut marble quoins, and the jailor's residence occupies the left side. Interior features include a large open stairway with reeded newel post and bannisters, and heavy iron-bound wooden doors of about four inches thickness between sections. Basement cells were lit by small windows opening into wells, and the basement is largely vaulted. An 1880 cell block was built within the original yard, which retains its 20-foot limestone wall. The nomination regards the jail as one of the oldest continuously used penal institutions in the country and as an example of Central Pennsylvania building traditions of its time. It also notes that the building has changed little, making it a useful record of penal history.","period_of_significance":"1817 to present","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Cell block still occupied; the 1880 cell block has three floors of cells still being occupied.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.903758-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/70000549.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/70000549/e41cf54471-800.webp","url_1600":"https://nationalhistoricalregister.com/media/70000549/e41cf54471-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Old_Jail_Cburg.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Old_Jail_Cburg.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994969","wikipedia":"https://en.wikipedia.org/wiki/Old_Franklin_County_Jail_(Chambersburg,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q5491413"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/franklin-county/franklin-county-jail-70000549/"}
