The Mission of Rancho Los Cerritos Historic Site

Collections Before and AfterThe mission of Rancho Los Cerritos Historic Site is to restore and preserve the structure and grounds; collect appropriate resources; and interpret the relationship of the Rancho’s diverse peoples, from Native American times through the 1940s, to the development of the Long Beach area.

This will be accomplished through a broad spectrum of educational programs, exhibits and publications designed to provide local residents, students and other visitors with an understanding of the forces that shaped this region.

To support the Mission Statement, the following objectives have been established:

  • to conduct, encourage, produce and share scholarly research on the history of Rancho Los Cerritos
  • to advocate, preserve and manage the site’s historical, architectural, botanical and archaeological resources
  • to collect, preserve and manage appropriate and authentic artifacts
  • to develop innovative and effective interpretive programs on Rancho Los Cerritos history
  • to supplement the teaching of local and Southern California history in the classroom
  • to encourage local history instruction in the schools and colleges
  • to expand resources and increase accessibility of the archives, research files and research library

Focus of Rancho Collections

Image of foreman's roomThe adobe ranch house, built in 1844, is the most important “artifact” at Rancho Los Cerritos, and the museum collections are aimed toward researching and sharing information about the house. For this reason, the most important collections include objects and archival materials that are directly associated with the Rancho and its owners, occupants and workers from prehistoric times through 1955.

The museum also collects artifacts, primary documents and photographs needed for research, exhibition and educational purposes in keeping with the mission statement. These items may be originals or items representative of those once found at the Rancho.

Furnishings in the exhibit rooms depict the work and leisure of both the owners and workers on a 19th century ranch. Handcrafted and mass produced objects demonstrate the changes occurring in America’s Victorian years, as well as the transition from a rural landscape to populated cities. Using various Bixby family reminiscences, many of the rooms are furnished with furniture, glass, ceramics, metals and tools from the 1870s.

The museum’s collections include more than 1,000 items of clothing and textiles from the 1830s-1930s. There are also over 1,100 historic photographic views of the rancho and its occupants, and various maps, letters, deeds and other documents relating to the site.

Archaeological Collections

Rancho Los Cerritos is designated as site number “LAn 696,” which refers to its registry in Los Angeles County as part of a statewide archaeological survey. The grounds under and surrounding the adobe are rich in archaeological materials. The site includes known trash pits from the 1840s-50s and from the 1870s-80s. The cache of “cogged stones” discovered in 1930 suggests that people have called this site home for at least 5,000 to 7,000 years.
