It holds 17 resources, mostly buildings from the second half of the 19th century.","why_significant":"The district is argued to be a very good example of a typical northern California mining town of the late 19th century. It is one of the earliest settlements in Trinity County and was a center for mining, commerce and transportation. Its simple, utilitarian buildings are linked to figures such as Olney Phillips.","narrative":"Lewiston Historic District covers the old center of a gold mining town in northwestern Trinity County, California. A one-lane bridge over the Trinity River leads into the Deadwood and Turnpike Roads intersection, where the store, butcher shop and houses cluster. The district runs about half a mile and holds 16 contributing buildings and structures, plus a bridge. Gabled roofs, wood construction, board and batten siding and front verandas are common, with a few Greek Revival details. Lewiston was founded in 1853 on mining and ranching and became a supply, transport and news center for miners. Olney Phillips, who ran a toll bridge and ferry and built a house in 1875, is among the figures tied to its buildings. The period of significance ends around 1925, when the town declined. It revived only in the 1950s with Trinity Dam, and development shifted to a new town to the east, leaving the old center largely unchanged.","period_of_significance":"1860-1925","architect_builder":"Multiple; examples include Olney Phillips (architect and builder of his 1875 house) and John Koll (builder of the 1899 Lewiston Hotel).","architectural_style":"No style; Greek Revival details; vernacular","criteria":["A","B","C"],"status_note":"Most contributors are described as in good condition with moderately high integrity. Several buildings are still in commercial, residential, school and community use, such as the hotel restaurant.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:26.991997-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/88000550.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/88000550/4c182942e7-800.webp","url_1600":"https://nationalhistoricalregister.com/media/88000550/4c182942e7-1600.webp","licence":"CC BY-SA 3.0","author":"Adrian Reed Smith (VivaLaPandaz)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Lewiston_Schoolhouse_Library.JPG\" rel=\"noopener\">Adrian Reed Smith (VivaLaPandaz)</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:Lewiston_Schoolhouse_Library.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123862201","wikipedia":"https://en.wikipedia.org/wiki/Lewiston_Historic_District_(Lewiston,_California)","wikidata":"https://www.wikidata.org/wiki/Q49516329"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/trinity-county/lewiston-historic-district-88000550/"}
