It has 15 significant structures built between 1888 and 1923, centered on 4th Street and a 1904 railroad depot.","why_significant":"The district preserves Santa Rosa's railroad-era commercial and industrial core, including rare brick commercial buildings that survived earthquakes and urban renewal. Four locally quarried stone buildings around a central park were built by Italian immigrant stonemasons, forming the most concentrated grouping of early stone buildings in Sonoma County. Freeway construction separated the area from downtown and left its character largely intact.","narrative":"Railroad Square is a compact commercial and industrial district at the western end of 4th Street in Santa Rosa, California. Its fifteen significant structures date from 1888 to 1923 and include brick warehouses along the tracks, one-story brick and stucco storefronts, two hotels and a 1904 depot. Four buildings around a central park, the Northwestern Pacific Depot, the Western Hotel, the La Rose Hotel and the Railway Express Agency building, were built of locally quarried stone by Italian immigrant stonemasons, forming the largest early stone cluster in Sonoma County. The area grew after the railroad arrived in 1871, serving travelers, workers and local industries such as mills, a tannery and wine cellars. Most buildings were rebuilt after the 1906 earthquake. The brick commercial buildings are especially valued because earthquakes and urban renewal destroyed most others in the city. Freeway construction in the 1960s cut the district off from downtown, which helped preserve its early twentieth-century appearance.","period_of_significance":"1888-1923","architect_builder":"Various; stone buildings by Italian stonemasons including Peter Maroni, Natale Forni, Massimo Galeazzi and Angelo Sodini","architectural_style":"Mixed commercial styles, including Mission Revival and Spanish Colonial Revival false-front storefronts, brick warehouses and stone buildings","criteria":[],"status_note":"Described as relatively unaltered, with remodeling and restoration only recently beginning; some buildings undergoing structural rehabilitation and some lots vacant.
