Leland Stanford, Collis Huntington, Mark Hopkins and Charles Crocker, the \"Big Four,\" planned, financed and built the western end of the first transcontinental railway here. They also took control of the Southern Pacific Railroad here. Significance rests on these events, not on architectural distinction.","narrative":"Originally three adjacent brick stores at 220-226 K Street in Sacramento, this building was put up in 1852 by Leland Stanford, Collis Huntington and Mark Hopkins. As their railroad venture grew, the structures were joined into one, with walls cut through to enlarge the office space. From 1862 to 1873 it served as the general offices of the Central Pacific Railroad, before the company moved to San Francisco. Here the four men known as the Big Four, with Charles Crocker, organized the western section of the first transcontinental railway, and they later founded the Southern Pacific Railroad. Its importance comes from those events rather than from its architecture. When urban renewal threatened the K Street neighborhood, the State of California carefully disassembled the building in 1966-67 and re-erected it on the north side of I Street in Old Sacramento. The exterior was renovated to its 1862-73 appearance, and it was being prepared as a museum.","period_of_significance":"1800-1899","architect_builder":"Built by Leland Stanford, Collis Huntington, and Mark Hopkins (1852)","architectural_style":"Commercial-style brick building","criteria":[],"status_note":"Disassembled by the State of California in 1966-67, reassembled on I Street and exterior restored to its 1862-73 appearance; owned by the State and described as work in progress, to open as a museum.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.490682-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/14000782_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/14000782/4d435a2887-800.webp","url_1600":"https://nationalhistoricalregister.com/media/14000782/4d435a2887-1600.webp","licence":"CC BY-SA 4.0","author":"Frank Schulenburg","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Big_Four_Building,_Old_Sacramento-4064.jpg\" rel=\"noopener\">Frank Schulenburg</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Big_Four_Building,_Old_Sacramento-4064.jpg"},"district":{"nrhp_refnum":"66000219","name":"Old Sacramento Historic District","url":"https://nationalhistoricalregister.com/districts/california/old-sacramento-historic-district-66000219/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123857994","wikipedia":"https://en.wikipedia.org/wiki/Big_Four_House","wikidata":"https://www.wikidata.org/wiki/Q4905730"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/sacramento-county/big-four-house-14000782/"}
