Louisiana, just east of the central business district in McKinney, Collin County, Texas. The main mill was built in 1914, with concrete grain elevators added about 1927.","why_significant":"The complex traces to the Burrus family's milling operations, which began in the 1870s and consolidated in 1892 into the Collin County Mill and Elevator Co. The Burrus family became leaders in the milling industry in the southwestern U.S. It is described as the city's best example of industrial architecture.","narrative":"This industrial complex at 407 E. Louisiana in McKinney, Texas, sits just east of the downtown business district on about 3.1 acres. Its two- and four-story load-bearing brick mill dates to 1914 and has a flat roof, steel-sash casement windows and large multi-paned industrial windows, with stepped brick detailing at the cornice. A brick office building and warehouse, also from about 1914, share its detailing. Concrete grain elevators were added about 1927, while newer silos do not contribute to the historic character. The business began in the 1870s, when W.C. Burrus and his son J. Perry Burrus ran a flour mill outside town. In 1892 they bought the Merchants Roller Mill, established in 1885, and merged the operations as the Collin County Mill and Elevator Co. The mill became a feed mill in the 1930s, and the Burruses became leaders in southwestern milling. The plant closed in the 1970s, and the site is now listed as vacant or used for storage. It is regarded as McKinney's best example of industrial architecture.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Present use is listed as vacant/storage, condition good; the plant closed in the 1970s.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:21.726554-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/21/9686/40968621/content/electronic-records/rg-079/NPS_TX/87001685.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40968621","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q110000105"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/collin-county/collin-county-mill-and-elevator-company-87001685/"}
