It is bounded by N. Washington St., W. Yaney Ave., N. Green St. and W. Jackson St.","why_significant":"The nomination extends the courthouse's boundary to include the square, which adds significance in social history and landscape architecture. It was designed by County Supervisor Frank J. Ralph and has served continuously as a public gathering place and a link between the courthouse and Veterans Memorial Hall. It keeps nearly all of its original design, materials and plantings.","narrative":"Courthouse Square is a single city block in the Gold Rush commercial district of Sonora, laid out in 1936 across from the 1898 Tuolumne County Courthouse. County Supervisor Frank J. Ralph designed it after the old brick Armory building on the site was demolished. Four diagonal pathways of local Columbia marble run from the corners to a central circle, dividing the block into four lawn sections. Trees chosen by Ralph, including London plane, cedar, redwood and pine, are all original, as are the privet hedges, green metal benches, cast iron light poles and wooden flagpole. A 1943 monument honors Ralph. Later changes are small: a brick fountain from the 1970s, a bus shelter and some signs. The square has served as a place to rest, gather and cross between the courthouse, Veterans Memorial Hall and nearby offices. Its inclusion adds social history and landscape architecture as areas of local significance to the courthouse listing.","period_of_significance":"1936-1956 and 1936","architect_builder":"Ralph, Frank J.","architectural_style":"No Style","criteria":["A","C"],"status_note":"Used continuously by the public since 1936 and maintained by the County; retains nearly all original features apart from small additions such as a monument, bus shelter and replacement brick fountain.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.712999-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/07000695.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123862303","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/california/tuolumne-county/tuolumne-county-courthouse-boundary-increase-07000695/"}
