The main building's drill hall was added in 1937, and the auxiliary building was constructed in 1927.","why_significant":"The armory has been an integral part of the Pennsylvania National Guard and is representative of the T-plan armories built in Pennsylvania, of which the nomination counts thirty-seven. It was constructed for Company D, 107th Field Artillery, in three phases between 1927 and 1937, and it is regarded as a member of the State Armory Building property type. Its architecture and military role both contribute to its significance at the state level.","narrative":"Built in three phases between 1927 and 1937, the Williamsport Armory occupies a sizable lot in the city and is laid out in a T-shaped plan. The two-story brick administrative block, completed in 1930, carries stone panels, brick buttresses and eight-light and sixteen-light casement windows, while the drill hall added in 1937 has a steel Pratt truss roof spanning about 5,400 square feet. A brick stable and gun shed dating from 1927 sit directly east of the main building. The complex served as a home for Company D, 107th Field Artillery, of the Pennsylvania National Guard. It is regarded as a representative example of the T-plan armories built across Pennsylvania, and its surviving interior spaces, including the drill hall, rifle range and offices, reflect how these facilities functioned for the state's guard units.","period_of_significance":"1927-1940","architect_builder":null,"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 17:13:34.420439-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/91001704.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/91001704/5b66744002-800.webp","url_1600":"https://nationalhistoricalregister.com/media/91001704/5b66744002-1600.webp","licence":"CC0","author":"Pubdog","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Williamsport_Armory_Apr_11.JPG\" rel=\"noopener\">Pubdog</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:Williamsport_Armory_Apr_11.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993356","wikipedia":"https://en.wikipedia.org/wiki/Williamsport_Armory","wikidata":"https://www.wikidata.org/wiki/Q8021264"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lycoming-county/williamsport-armory-91001704/"}
