One of the most tangible connections to that period still stands along Mission Road.
The Frink Adobe, constructed in 1874 by Horace Monroe Frink, is recognized as one of Loma Linda's most significant historic structures. More than 150 years after its construction, preservation advocates are working to ensure that the building remains part of the city's future.
The project gained renewed attention this fall when the San Gorgonio Pass Historical Society hosted a presentation titled "Bringing the Frink Adobe Back to Life" on October 8.
Jim Shipp, representing Two Canyons Conservancy, discussed the property's history and the effort to preserve it as a cultural and educational resource.
Horace Frink arrived in California during the nineteenth century and became involved in ranching, transportation and agricultural development. His family's activities were connected to San Timoteo Canyon and the early growth of the San Bernardino Valley.
The Frink family was also associated with early citrus cultivation in the Mission District, an industry that would eventually transform much of Southern California's landscape.
According to the Redlands Area Historical Society, the Frink Adobe is the only Loma Linda structure listed on the California Register of Historical Resources.
For generations, members of the Frink family lived in the house, creating a direct connection between the city's early settlement period and later development.
Preserving such a structure is not as simple as repainting a modern home.
Adobe buildings were constructed using earthen materials that require specialized attention. Water intrusion, structural movement and deterioration can threaten walls and foundations.
Restoration work must therefore balance structural safety with the need to preserve historic materials and construction methods.
During Loma Linda's May 4 Historical Commission meeting, the proposed rehabilitation was considered under Precise Plan of Design Permit No. 2025-0008.
The project involves the Frink Adobe property within The Groves at Loma Linda Specific Plan.
Shipp explained that Lennar Homes had transferred ownership of the historic property to Two Canyons Conservancy because of its historical significance.
The conservancy intends to develop the property as an educational and cultural resource, with interpretive displays addressing the area's history.
Potential subjects include Mission Road, the Zanja Trail, the historic Kaawchama village, citrus cultivation and traditional adobe construction.
The project team has also described collaboration with representatives of the San Manuel Band of Mission Indians to incorporate Indigenous history and perspectives into the educational experience.
Indigenous communities lived in and shaped the area long before California's American settlement period.
A meaningful historical resource should help visitors understand those earlier experiences alongside the agricultural and transportation history represented by the Frink family.
The rehabilitation proposal includes attention to deteriorated walls, foundation conditions, grading and drainage.
Those technical details may seem less interesting than the stories associated with the building, but they are essential to ensuring that the adobe survives.
The project remains a preservation effort rather than a completed public museum. Its final opening date, public access arrangements and full restoration costs have not been confirmed in the sources reviewed.
Nevertheless, preservation advocates are continuing to introduce the project to the public.
On November 5, the San Bernardino Historical Society is scheduled to host another presentation by Shipp concerning the Frink Adobe Historic Park and plans for its future.
The society's announcement indicates that Shipp expects to discuss an upcoming public event connected to the site's development.
For Loma Linda residents, the project presents an opportunity to protect something that cannot be replaced once lost.
Modern buildings can be constructed using new materials and designs. A nineteenth-century adobe containing generations of local history cannot simply be recreated with the same authenticity.
The Frink Adobe also offers potential educational value for students, families and visitors interested in understanding how Loma Linda developed.
Its preservation could provide a place where the city's agricultural past, Indigenous history and changing landscape are explored together.
As new homes and businesses continue to shape Loma Linda, the adobe serves as a reminder that growth and preservation need not be opposing goals.
A community can prepare for the future while protecting the places that explain where it began.
And if the restoration succeeds, one of Loma Linda's oldest buildings may become a place where new generations discover stories that might otherwise disappear.
