Its sawtooth roof with skylights is noted in the development of industrial architecture and resembles the Cone Mills White Oak Plant in Greensboro. The architect is unknown.","narrative":"Built in 1911 at Marshall and Second streets in Winston-Salem, this one-story brick mill with a daylight basement and sawtooth roof was the first plant of what became the Hanes Hosiery Company. It began as Shamrock Knitting Mills, founded by John Wesley Hanes, and took the name Hanes Hosiery Mills Company in 1914. The building held about 200 knitting machines and 200 employees. Its roof, with six-foot skylights over seven sections, followed a design popular in textile mills of the early twentieth century and closely resembles the 1902-1903 White Oak Plant of Cone Cotton Mills in Greensboro. The architect is unknown. Knitting took place at street level, while dyeing and boarding of stockings were done in the basement. Hanes moved to a larger West 14th Street plant by 1926, and Carolina Cadillac Company then used the building as a dealership, adding a store-front facade. It was listed as a reminder of the company's beginnings and for its roof design.","period_of_significance":"1911","architect_builder":null,"architectural_style":"Sawtooth-roof industrial mill; 1925 office addition suggestive of the Bauhaus school","criteria":[],"status_note":"Listed as unoccupied/vacant at the time of nomination; later used as a Carolina Cadillac dealership after Hanes moved in 1926, with a store-front facade added.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:58:56.875458-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/26/7202/47720226/content/electronic-records/rg-079/NPS_NC/78001951.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78001951/b67c436040-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78001951/b67c436040-1600.webp","licence":"CC BY-SA 3.0","author":"Jerrye &amp; Roy Klotz, MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:SHAMROCK_MILLS,_FORSYTH_COUNTY,_NC.jpg\" rel=\"noopener\">Jerrye &amp;amp; Roy Klotz, MD</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:SHAMROCK_MILLS,_FORSYTH_COUNTY,_NC.jpg"},"district":{"nrhp_refnum":"100008467","name":"Downtown Winston-Salem Historic District","url":"https://nationalhistoricalregister.com/districts/north-carolina/downtown-winston-salem-historic-district-100008467/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/47720226","wikipedia":"https://en.wikipedia.org/wiki/Shamrock_Mills","wikidata":"https://www.wikidata.org/wiki/Q21016176"},"indexable":true,"url":"https://nationalhistoricalregister.com/north-carolina/forsyth-county/shamrock-mills-78001951/"}
