and Beaux-Arts styles, with large formal buildings around large symmetric spaces. Even San Francisco's simultaneous Panama–Pacific International Exposition was largely, though not exclusively, in Beaux-Arts style. Goodhue had already experimented with Spanish Baroque in Havana, at the 1905 La Santisima Trinidad pro-cathedral, and the Hotel Colon in Panama. Some of his specific stylistic sources for San Diego are the Giralda Tower at the Seville Cathedral, the Mexico City Metropolitan Cathedral, and the Cathedral of Our Lady of the Assumption, Oaxaca. Goodhue personally designed the largest and most ornate building on the site, the California Building, with its historical iconography; he sketched two other buildings, provided Winslow and Allen with his photographs and drawings from examples in Spain and Mexico, and reviewed their developed designs. The original ensemble of buildings featured various stylistic and period references. Taken together, they constituted something like a recapitulated history of Spanish colonial in North America, from Renaissance Europe sources, to Spanish colonial, to Mexican Baroque, to the vernacular styles adopted by the Franciscan missions up the California coast. The Botanical Building was designed by Winslow with help from Allen and Thomas B. Hunter in the style of a Spanish Renaissance greenhouse. This mix of influences at San Diego proved popular enough to earn its own name: Spanish Colonial Revival. The Exposition brought Spanish Colonial Revival into becoming California's "indigenous historical vernacular style", very popular in poured concrete through the 1920s, still used and reinterpreted in the present day. To some extent it was even adopted as a southwestern regional style, as seen at the Pima County Courthouse in Tucson, Arizona, with a few minor examples in Phoenix. Prior to the exposition, San Diego had predominately featured Victorian architecture with some elements of classical styles. The popularity of the expo led to more emphasis on mission architecture within the city. Goodhue moved on to other national projects, while Winslow stayed on in southern California, continued to produce his own variations of the style, at the Bishop's School in La Jolla and the 1926 Carthay Circle Theatre in Los Angeles. Winslow was also instrumental in persuading the city of Santa Barbara to adopt Spanish Colonial Revival as the officially mandated civic style after its 1925 earthquake. The major example from the rebuilding is the Santa Barbara County Courthouse. The temporary installations, decoration, and landscapes of Balboa Park were created with some large spaces and numerous paths, small
