It was built in 1938 and occupies about 25,726 square feet.","why_significant":"The nomination argues the armory is significant under criteria A and C as one of nine armories built in Pennsylvania between 1912 and 1938. It was built for a Pennsylvania National Guard cavalry unit and follows the I-plan layout typical of such armories, with a riding hall, stable wing, rifle range, locker rooms and offices.","narrative":"Built in 1938 on a ten-acre lot in Logan Township, just outside Altoona, the armory is a one-story brick building in the Moderne style, designed by Frank Austin Hersh of Altoona. Its I-shaped plan places a riding hall between an administrative wing at the front and a former stable wing at the rear, and the riding hall is covered by a round arched roof. The main elevation has a centrally placed entrance under a brick segmental arch, with multi-light casement windows and brick belt courses on the sides. The building was constructed for a Pennsylvania National Guard cavalry unit, and it is one of nine armories built in the state between 1912 and 1938. It is important for its military use and for its architecture, and the interior retains a riding hall measuring 90 by 140 feet. The property retains very good integrity, though the stable was converted to storage and work space and the riding hall floor was concreted.","period_of_significance":"1938-1939","architect_builder":"Frank Austin Hersh (architect)","architectural_style":"Moderne","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 17:11:36.626219-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/91000507.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/91000507/e2fc35eebe-800.webp","url_1600":"https://nationalhistoricalregister.com/media/91000507/e2fc35eebe-1600.webp","licence":"Public domain","author":"Pubdog","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Altoona_Armory_Apr_12.JPG\" rel=\"noopener\">Pubdog</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Altoona_Armory_Apr_12.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992428","wikipedia":"https://en.wikipedia.org/wiki/Altoona_Armory","wikidata":"https://www.wikidata.org/wiki/Q4736947"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/blair-county/altoona-armory-91000507/"}
