The Village of Cordelia Historic District was added to the National Register of Historic Places in 1988 with a period of significance from 1870 to 1939. The district extends along Cordelia Road from Interstate 680 to Pittman Road and includes Bridgeport Avenue south of the railroad tracks, where several classic Victorian-era homes still stand. It originally contained 39 properties, including 23 single-family residences, 6 commercial or civic structures, 3 farmsteads, and 7 other buildings, though many no longer exist. Cordelia was regarded as one of the best-preserved villages in California, illustrating in its plan and structures the basic character of village life in California in the late nineteenth and early twentieth centuries. Cordelia was once the largest wine producer in the United States, and the Cordelia Wine Company, established in 1867 as the first winery in Solano County, shipped wine on its own railroad spur and by ships that could sail to the end of Cordelia Slough. Soil eroding from agricultural land in Suisun Valley and Green Valley eventually caused Cordelia's embarcadero to silt up and become unusable, though some original dock piles remain in the Suisun Marsh. The Cordelia Wine Company closed in the 1920s because of prohibition; its wooden structures later burned, but the stone wine cellar survives. Cordelia's town center stood close to the railroad and included a train depot, Cordelia Meat Market with Glashoffs Dance Hall on the second floor, a post office building that also housed the library and barber shop, and Siebe's General Store. About a mile east stands Solano County's only railroad tunnel, built in 1868 as part of the transcontinental railroad and still in use, hand dug by Chinese rail workers with picks and shovels rather than explosives.
