Built in 1852, the Big Four House was named after the "big four"--Collis Huntington, Mark Hopkins, Leland Stanford, and Charles Crocker--who planned, financed, and built the Western end of America's first transcontinental railway. It was in this structure that the four made their offices while organizing the Central Pacific (California to Utah) section of the railway, and where subsequently they founded the Southern Pacific Railroad (to Southern California) in 1873.
