Its administrative section fronts the road, a 60 by 90 foot drill hall with a wood floor and riveted steel Fink-type trusses sits at the center, and a former stable wing with a second-floor hay loft extends to the rear. The building covers about 14,028 square feet and retains very good integrity, with much of its original woodwork, doors and casement windows intact. It was built as a federal public works project, most likely for the 104th Machine Gun Troop of the Pennsylvania National Guard. It is one of nine I-plan armories built in Pennsylvania between 1912 and 1938, and the plan type was used for cavalry units, whose stables and grazing needs led most such buildings to be placed on the edges of towns.","period_of_significance":"1938-1939","architect_builder":"Lawrie and Green (architect)","architectural_style":"Colonial Revival","criteria":["A","C"],"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 17:11:36.175689-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/91000513.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/91000513/c1f5a8f253-800.webp","url_1600":"https://nationalhistoricalregister.com/media/91000513/c1f5a8f253-1600.webp","licence":"Public domain","author":"Pubdog (talk)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Lewistown_Armory_Apr_10.JPG\" rel=\"noopener\">Pubdog (talk)</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Lewistown_Armory_Apr_10.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993374","wikipedia":"https://en.wikipedia.org/wiki/Lewistown_Armory","wikidata":"https://www.wikidata.org/wiki/Q6537430"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/mifflin-county/lewistown-armory-91000513/"}
