I copied this from Wikipedia because I think it’s interesting.
“While the architecture from this period (mid-1800s) is commonly attributed to Victorian gold miners, characteristics of West End, such as multi-storied buildings, large arched doorways, full-height balcony windows and the use of decorative wrought-iron balconies, were most ubiquitous in parts of Spain and the Spanish colonies. This influence may be attributed to the fact that the period of Spanish rule in California enjoyed immigration from all over the Atlantic, including Spain and the Canary Islands, and the Spanish colonies.
The architecture of Old Town Sacramento (formerly known as West End) exhibits observable characteristics similar to that of San Juan (Puerto Rico), Havana (Cuba), Tampico (Mexico), Seville (Spain), Santa Cruz de Teneriffe (Canary Islands), Madrid (Spain).
While the architectural style of Old Sacramento, with its wrought iron balconies and evenly-spaced full height windows may remind one of Paris, it should be noted that Sacramento’s oldest buildings predate the Haussmann Projects that renovated large areas of Paris in that style.”
