Built in 1901 by Joseph Asch to designs by John Woosley, it was originally the Asch Building and is now the Brown Building.","why_significant":"The Triangle Shirtwaist Factory occupied the eighth, ninth and tenth floors, and the fire there on March 25, 1911 killed 146 workers, mostly young women. The tragedy galvanized the labor movement and led to the New York Factory Investigation Commission and dozens of new state labor and safety laws. The building is also tied to the 1909 strike known as the Uprising of the Twenty Thousand and to labor figures Rose Schneiderman, Mary Breier and Clara Lemlich.","narrative":"Built in 1901 as an industrial loft at 23-29 Washington Place in Greenwich Village, this ten-story building was designed by John Woosley for developer Joseph Asch. It has a stone base, brick upper walls, terra-cotta trim and a round-arched arcade below a projecting cornice. In 1902 the Triangle Shirtwaist Factory took the eighth, ninth and tenth floors. On March 25, 1911, a fire swept the factory and killed 146 workers, mostly young women. Many were trapped by locked doors, and the fire department's ladders reached only the sixth floor. The disaster followed the 1909 garment workers' strike and drew public outrage. Speeches by organizers such as Rose Schneiderman helped build support for reform. The resulting state commission led to thirty-six new New York labor laws by 1914, and the fire is cited as a turning point in American labor history. The exterior remains largely intact above the altered ground floor, while the interior has been remodeled for New York University classrooms and offices. Union members still gather outside each year to commemorate the victims.","period_of_significance":"1901-1911","architect_builder":"John Woosley","architectural_style":"Late 19th and 20th Century Revivals: Neo-Renaissance","criteria":["A","B"],"status_note":"Owned by New York University and used for classrooms and offices; the interior has been extensively remodeled and retains no signs of the factory.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:39.46816-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/91002050_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/91002050/f1a9b1e6d7-800.webp","url_1600":"https://nationalhistoricalregister.com/media/91002050/f1a9b1e6d7-1600.webp","licence":"CC BY-SA 4.0","author":"Epicgenius","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Greenwich_Village_Manhattan_Oct_2025_51.jpg\" rel=\"noopener\">Epicgenius</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Greenwich_Village_Manhattan_Oct_2025_51.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75315920","wikipedia":"https://en.wikipedia.org/wiki/Brown_Building_(Manhattan)","wikidata":"https://www.wikidata.org/wiki/Q4976083"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/manhattan/triangle-shirtwaist-factory-91002050/"}
