The Historic and Decorative Arts Collections were the first focuses of the museum. This varied collection includes historic costumes, military uniforms and textiles, furniture, dolls and toys, tools, and house wares, many of which were collected from the founding families of Orange County. The Orange County history collection contains historic newspapers, magazines and other publications, as well as photographs, art, and objects relating to the early days of Orange County. Highlights of this collection include objects relating to Madame Helena Modjeska and memorabilia and objects from the first police and fire departments of Santa Ana. The large photographic collection includes books, maps, posters, stereographs, and slides but is most notable for photographs.
