Origin
In 1911, Goodhue was hired as consulting architect for the exposition marking the opening of the Panama Canal, and proposed the Spanish colonial style — which he had been researching since a trip to Mexico in 1899 — as the central theme, breaking from the tradition of using classical Greco-Roman references at world's fairs. This was the first time an American exposition adopted this language as a unifying concept, which helped cement it as a residential and institutional style in the following decades.
