A noncontributing metal storage shed and a brick vehicle maintenance building stand on the grounds.","why_significant":"The armory is significant under criteria A and C as one of nine armories built in Pennsylvania between 1912 and 1938 that follow the I-plan type. It was built as a federal public works project for Troop K, 103rd Cavalry of the Pennsylvania National Guard. Its design by the Thayer Company of New Castle and its very good integrity, including original windows, support its significance.","narrative":"Built in 1938 on a spacious lot in Shenango Township, just outside New Castle, the armory is an Art Deco complex of ashlar stone designed by the Thayer Company of New Castle. It was constructed as a federal public works project for Troop K, 103rd Cavalry of the Pennsylvania National Guard. The building follows an I plan: a one-story riding hall with a bowstring roof, joined to a front administrative section and a two-story rear former stable. The riding hall measures 66 by 145 feet and is supported by riveted steel Warren bowstring trusses. Its layout reflects the cavalry use, with stables at the rear and grazing needs and odors leading to an outskirts location common to such armories. It is one of nine Pennsylvania armories of this type built between 1912 and 1938. The main building retains very good integrity, including its original windows, and the stable was renovated to provide administrative rooms.","period_of_significance":"1938-1939","architect_builder":"Thayer Company (architect)","architectural_style":"Art Deco","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 17:11:36.354663-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/91000516.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/91000516/52a02b874a-800.webp","url_1600":"https://nationalhistoricalregister.com/media/91000516/52a02b874a-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:New_Castle_Armory.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:New_Castle_Armory.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993312","wikipedia":"https://en.wikipedia.org/wiki/New_Castle_Armory","wikidata":"https://www.wikidata.org/wiki/Q7006403"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lawrence-county/new-castle-armory-91000516/"}
