Recently designated a National Historic Landmark, the 1925 Spanish Colonial named Casa del Herrero, or House of the Blacksmith, in Montecito, Calif., is a breathtaking example of the American Country Place era. Munitions manufacturer George Fox Steedman built this Moorish-inspired house, long regarded as one of the Santa Barbara area's most impressive design landmarks. But the truth is, historians consider the surrounding gardens just as sublime.
