The Pueblo Revival style or Santa Fe style is a regional architectural style of the Southwestern United States, which draws its inspiration from Santa Fe de Nuevo México's traditional Pueblo architecture, the Spanish missions, and Territorial Style. The style developed at the beginning of the 20th century and reached its greatest popularity in the 1920s and 1930s, though it is still commonly used for new buildings. Pueblo style architecture is most prevalent in the state of New Mexico; it is often blended with Territorial Revival architecture.
