The turn-of-the-century house style known as Mission – (or Spanish Mission, California Mission, or Mission Revival) – was inspired by the historic mission churches built by Spanish priests and colonists in the late 18th century. The earliest Mission style homes were built in California. Though the style spread eastward, most Mission style homes are found in the southwestern states, where they reflect the architecture of their Hispanic settlers. The Mission style movement enjoyed its greatest popularity between 1890 and 1915. By the 1920’s, architects were combining features from other movements including: Prairie, Pueblo, Arts & Crafts. Mission style architecture evolved into the Spanish Colonial Revival style, which has historical, nostalgic, cultural, and environmental associations. The homes’ climate-appropriateness makes this architectural style predominant in the Southwest, especially in California. Spanish Revival homes became popular in California during the 1920’s following the Panama-California Exposition, which took place in San Diego from 1915-1917.
