Under Criterion A it was one of the first permanent structures in Garrote (Groveland) and has been central to the town's commercial and social life, first as a mercantile store and since 1896 as a saloon.","narrative":"Built around 1851 in the Gold Rush settlement of Garrote, now Groveland, this single-story stone building on Highway 120 was first the Watts and Tannahill Company Store, commonly called the Granite Store. Its front and rear walls are carefully cut granite blocks, with slate used for the side walls and basement. The nomination describes it as the only Gold Rush era stone building left in Groveland and notes that the use of cut granite appears unique to this store. It served as a mercantile from about 1850 until the late 1880s, and James Tannahill was postmaster from 1863 to 1880. Giacomo De Ferrari opened a saloon here in 1896, and the building has operated as a saloon or bar ever since, known as the Iron Door Saloon for its iron fire doors. Later buildings were added on both sides and a large gable roof now covers it, yet the granite front remains distinct. The property was listed for its architecture and its role in the town's early settlement.","period_of_significance":"1851","architect_builder":"unknown","architectural_style":"Mid-19th Century/other: stone commercial","criteria":["C","A"],"status_note":"Still in use as the Iron Door Saloon, a bar and restaurant, and undergoing slow restoration by its owners.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.651362-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/95000265.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/95000265/039ccbc63c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/95000265/039ccbc63c-1600.webp","licence":"CC BY-SA 3.0","author":"Almonroth","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Watts_and_Tannehill_Country_Store-2.jpg\" rel=\"noopener\">Almonroth</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:Watts_and_Tannehill_Country_Store-2.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123862311","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q130337419"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/tuolumne-county/watts-and-tannahill-company-store-95000265/"}
