Spanish by way of colonial Mexico, the Spanish Colonial Revival style in architecture and design has been part of the aesthetic fabric of Southern California for over 100 years. While contributions and landmarks in many parts of the region are well known, those aspects of the Inland Empire have largely been forgotten. As one of the wealthiest cities in America in the late nineteenth century, Riverside had capital and prestige that its civic leaders and entrepreneurs were willing to invest to create a built environment that would recognize the citrus industry and lure tourists and settlers to the area. Landmarks in its downtown core include First Congregational Church, designed by Myron Hunt with Churrigueresque flourishes (1912?1914) and the historic Mission Inn, which evolved architecturally from A.B. Benson's original plan of 1903, with additions by Hunt and Elmer Grey, as well as G. Stanley Wilson, one of the main practitioners of the Spanish Colonial Revival in Riverside. The volume will be the first comprehensive documentation and analysis of the substantial contributions to the origins and later iterations of the Spanish Colonial Revival style in California's Inland Empire region.
