It is a representative example of adobe construction practiced by the Spanish before 1850 and by some of the first Californians. The slightly raised slate foundation is also typical of the period, and the building apparently served as an early post office, possibly adapted during the gold rush years.","narrative":"This rectangular adobe building at Yosemite Boulevard and La Grange Road in La Grange is described as the oldest structure in the community. Its walls are made of adobe bricks roughly 16 to 18 inches long and 3 to 4 inches thick, set on a slightly raised slate foundation. Both the brick construction and the foundation reflect building practices used by the Spanish before 1850 and by some of the first Californians. The building is believed to have served as a post office early in the town's history. It may have been built for that purpose in the early 1850s, or adapted for it during the gold rush years, and it may first have been a residence or ranch outbuilding. Later changes include redwood siding on the front, a wood shed attached to one side, a protective tin roof, and large wooden boards bolted to the side and rear walls to slow deterioration. Many of the wood additions appear to date from its use as a barn.","period_of_significance":null,"architect_builder":null,"architectural_style":"Adobe construction with slate foundation (pre-1850 Spanish/early Californian building practice)","criteria":[],"status_note":"Condition rated fair; present use is barn and storage, and the property is publicly owned by the county.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.15287-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/79003462.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79003462/f03c85533d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79003462/f03c85533d-1600.webp","licence":"CC BY-SA 3.0","author":"Mirokuofnite","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Old_Adobe_Barn.JPG\" rel=\"noopener\">Mirokuofnite</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:Old_Adobe_Barn.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123857832","wikipedia":"https://en.wikipedia.org/wiki/Old_Adobe_Barn","wikidata":"https://www.wikidata.org/wiki/Q7083363"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/stanislaus-county/old-adobe-barn-79003462/"}
