- U.S. Custom House - Naco AZ"The Custom House at Naco was constructed in 1936 with funds from the Public Works Administration. Louis Simon, architect for the Public Buildings Branch of the Treasury Department, designed the Custom House in the Pueblo Revival style. The two-story building is an outstanding example of this style and includes southwestern features of battered (sloped) and rounded walls, parapets, rough-hewn rafters and vigas, waterspouts, window lintels, and a decorative ladder. In addition to its fine artistry and historic integrity, the building is the only Custom House on the Arizona border designed in the Pueblo Revival style."
