The core buildings were designed by Cass Gilbert and built in 1918-1919, with additions made in 1942-1944.","why_significant":"The nomination argues the terminal is a monumental early example of modern industrial design and advanced reinforced-concrete engineering by a nationally prominent architect. Its warehouses were the largest reinforced concrete structures in the world when built. It also served as a major debarkation point for troops and supplies in both World Wars, linking rail and maritime transport.","narrative":"Along the Brooklyn waterfront between 58th and 65th Streets, this former Army port complex occupies 97 acres beside Upper New York Bay. Eleven structures contribute to its significance, including two giant reinforced concrete warehouses, an administration building, a boiler house, and piers, built in 1918-1919 to designs by Cass Gilbert. Warehouse B holds a skylit atrium 740 feet long, and bridges and tunnels join the main buildings. Rail lines run through the site and along the piers. The warehouses were the largest reinforced concrete structures in the world when built, using a column-and-slab system with flared column heads. The terminal handled returning troops and materiel after World War I and was a main departure point in World War II, when more than 3,000,000 troops and 38,000,000 tons of supplies passed through. A gate house, laundry, and a pre-existing officers' house are also counted. The government vacated the site in 1975, and New York City acquired it in 1981.","period_of_significance":"1918 - 1944","architect_builder":"Cass Gilbert; Post and McCord (engineers, Pier I); U.S. Army Corps of Engineers (1942-44 buildings)","architectural_style":null,"criteria":[],"status_note":"Vacated by the U.S. government in 1975 and acquired by the City of New York in 1981 for conversion to manufacturing, warehousing, office and maritime uses; classified as unoccupied and vacant, with condition checked as good and altered.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:43.528411-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/83001702.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/83001702/2a20c0bd0d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/83001702/2a20c0bd0d-1600.webp","licence":"CC BY-SA 2.0","author":"Dennis from Нью-Йорк, Россия","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Brooklyn_Army_Terminal_samsebeskazal.livejournal.com-05895_(11061174314).jpg\" rel=\"noopener\">Dennis from Нью-Йорк, Россия</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Brooklyn_Army_Terminal_samsebeskazal.livejournal.com-05895_(11061174314).jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75318546","wikipedia":"https://en.wikipedia.org/wiki/Brooklyn_Army_Terminal","wikidata":"https://www.wikidata.org/wiki/Q929358"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/brooklyn/u-s-army-military-ocean-terminal-83001702/"}
