It is described as unique in the area and as suggestive of the work of Philadelphia architect Frank Furness. It is also an important visual component of downtown Stockton and a remnant of the city's early fabric.","narrative":"Built in 1892 for wealthy farmer John Tretheway, this brick commercial building at 229 East Weber Street in downtown Stockton originally held a hardware store on the ground floor with offices and lodging rooms above. Around 1925 it became the Hotel Argonaut, which operated until the mid-1970s. Its facade is the main reason for its recognition. Two three-story arched bays with ribbed, iron-sheathed partial domes flank three narrower arched bays, and three-dimensional zinc floral reliefs fill the spandrels and lunettes. A cornice of small corbelled arches adds Romanesque character, while the domes and banding suggest Moorish themes, all within a Queen Anne framework. The original stone parapet fell in the 1906 earthquake. The nomination calls the design unique in a region of more conservative architecture and notes its value to the downtown streetscape. Planned work included restoring wood windows, cast iron columns, transoms, and a decorative oval skylight.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":"Queen Anne with Romanesque and Moorish influences","criteria":[],"status_note":"The hotel closed in the mid-1970s; the form describes planned rehabilitation and restoration work, including the facade, ground floor, and interior.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.59573-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/82000987.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82000987/16e4daf2f3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82000987/16e4daf2f3-1600.webp","licence":"CC BY-SA 3.0","author":"Michael Aivaliotis","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Tretheway_Block_-_Stockton,_CA.jpg\" rel=\"noopener\">Michael Aivaliotis</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:Tretheway_Block_-_Stockton,_CA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123861427","wikipedia":"https://en.wikipedia.org/wiki/Tretheway_Block","wikidata":"https://www.wikidata.org/wiki/Q14684160"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/san-joaquin-county/tretheway-block-82000987/"}
