Castro Adobe Project

California's Newest State Historic Park

About the Castro Adobe

Friends led a 20-year restoration effort to preserve and interpret the Castro Adobe as the newest State Historic Park in California in partnership with California State Parks. When plans are completed, the park will be Santa Cruz County’s second State Historic Park and the first non-beach State Park in the Pajaro Valley. The Castro Adobe is open on a limited basis for special events, such as Open House Days.

The Castro Adobe is one of the finest examples of a rancho hacienda in the Monterey Bay area. It is an excellent representation of a Monterey-Colonial style adobe. It is only one of four historic adobe buildings remaining in Santa Cruz County. One is a private home in Santa Cruz, the Craig Lorenzana Adobe, and the other two are the Bolcoff Adobe at Wilder Ranch State Park and the adobe at the Santa Cruz Mission State Historic Park. The Castro adobe is included in the National Register of Historic Places and is a California Historic Landmark.

Friends undertook the restoration of the Castro Adobe, the only remaining building of the Rancho era in the Pajaro Valley, to increase equity and access to an otherwise untold story in the region. The Castro Adobe symbolizes the deep roots of Mexican culture in the Pajaro Valley, as well as California.

Castro Adobe State Historic Park serves visitors interested in adobe architecture and preservation, as well as fourth graders studying the Mexican Rancho period and third graders studying local history. In the cocina (kitchen), the link between Latino traditions of today and Californio heritage are tangible as students experience cooking and feeding the people at the rancho including making tortillas, beans and nopales (cactus).

Future Plans

Friends is launching the final phase of creating the Castro Adobe house museum, which will include: installing educational exhibits and furnishings in the adobe. The end result of this effort will be a carefully restored historic adobe building with innovative interactive exhibits and loads of community support.

After completion of the musuem, Friends will complete California’s newest State Historic Park, which will include: establishing the Kimbro House Visitor Center & Archive; restoring the habitat lands leading to the nearby stream; creating accessible paths; installing parking and restrooms; and making the park a leader in sustainability.

The Rancho San Andrés Castro Adobe is one of the grandest of all adobe buildings representing the Mexican Rancho Period of California history (1821-1848). The Rancho period began as Mexico first gained its independence from Spain and ended when California became part of the United States. Mission lands were secularized during this period and families such as the Castros were granted large swaths of land to build on and use for ranching.

Located near Watsonville, this two-story adobe hacienda features a spacious fandango room on the second floor and an original cocina, one of the very few remaining original rancho cocinas in California. The original carreta (cart or wagon) road to the adobe is still in use, providing a tangible link to the history of the site. Below is a timeline of the Castro Adobe. Click here for a printable Castro Adobe timeline.

Aptos Tribe

Santa Cruz County is the ancestral home for many tribes of independent Awaswas-speaking Ohlone people. Rancho San Andrés is situated in the homelands of one of these tribes – the Aptos.

The Aptos people are one of the tribes who lived in the Monterey Bay region, known to them as Calendaruc [Ka-linta Ruk]. Calendaruc means “ocean houses,” which describes their location in the Monterey Bay.

Centuries of colonial violence led to the destruction of the Aptos, and today there are no known Aptos people. Today, neighboring tribes like the Amah Mutsun Tribal Band continue their stewardship and presence in these lands to honor the Aptos and ensure they are never forgotten.

Anza Expedition


Anza Expedition brings soldiers and settlers to San Francisco from Sinaloa, Mexico. In this group are Joaquin Isidro Castro and his wife Martina Boutillier and their large family, including seven-year-old Jose Joaquin Castro.


Mission Santa Cruz is established and later Jose Joaquin Castro and his family are connected to the mission having various administrative duties. California is under Spanish rule.


After 1821, the missions are secularized (closed) and land grants are awarded to well-connected persons. California is under Mexican rule.


Governor Arguello grants conditional possession of Rancho San Andrés to Jose Joaquin Castro (more than 8,800 acres) which reaches from the Monterey Bay to Corralitos and from the Pajaro River to Aptos with full ownership to come years later in 1857. Jose Joaquin constructs early rancho buildings near the ocean on present day San Andreas Road.


The Castro Adobe was constructed by native servants for Juan Jose Castro and Rita Pinto Castro. His brother, Guadalupe Castro, is partial owner of the rancho at this time.


The large Castro family lives in the adobe and continues work on the rancho. Exemplifying their role in the community, Juan Jose and his brother, Guadalupe Castro are elected Justices of the Peace in 1851. Soon afterwards Juan Jose becomes a County Supervisor. In 1857, the U. S. Land Commission formally confirms Rancho San Andrés to the heirs of Jose Joaquin Castro. California is under American rule.


The U.S. Land Commission brings legal dispute against Juan José and Guadalupe Castro. They ultimately lose the land due to court costs a year later. The Castro Adobe is sold at state auction for $2,000. The Castro family continues to live on the land as renters until the sale to Hans Hansen and his wife, Margaretta, in 1873.


End of Hansen family ownership and a succession of people own the adobe building but by the 1930s, the building is described as ‘decaying in dignity’.


Resurgence in interest in the historic adobe building and it undergoes a series of attempts to rehabilitate the structure including projects by owners Holtzclaw (1940s), Nelson (1950s), and Paizis (1960s).


Elizabeth and David Potter purchase the property. Landscape architect Thomas Church sketches the concept for the garden at the rear of property, now known as the Potter-Church garden.


Edna and Joe Kimbro purchase the property. Castro Adobe damaged by 1989 Loma Prieta Earthquake.


After years of community advocacy, the one-acre parcel, including the Castro Adobe, is acquired by California State Parks.


Friends of Santa Cruz State Parks (Friends) partners with California State Parks on the Castro Adobe project. Friends manages the building of 2,500 adobe bricks for use in reconstruction.


During this period, the building was restored including the Potter Church garden, the cocina
(historic kitchen), seismic stabilization and lighting. An exposed steel beam was engineered to support the second floor and a lift installed to provide access for all. Other work included electrical upgrades, installation of historic furnishings, new fire suppression system and interpretive planning for the eventual opening of the park.

The Castro Adobe was built between 1849-1850 by native servants for Juan Jose Castro and Rita Pinto Castro. Juan Jose was son of Jose Joaquin Castro, who was an original Juan Bautista de Anza Expedition member. The Castro Adobe on the family’s land grant, Rancho San Andrés. The rancho spread over two square leagues (8,800 square acres) stretching from the Monterey Bay to Corralitos and from the Pajaro River to Aptos. Eventually the extended Castro family owned over 250,000 acres from Pajaro to Aptos to Soquel and north almost to Davenport. Native servants did much of the work at the Castro Adobe including constructing the buildings, tending the crops, managing the cattle and cooking and serving the food at the rancho.

The Castro family raised cattle for trading hides and producing tallow at the two-story adobe and on the surrounding land. They enjoyed fandangos on the second floor, as food was prepared on the long brasero (masonry range) in the cocina. The fandangos featured dancing, music and food to entertain the Castro family and friends. The family fished at nearby beaches, caught frogs in the sloughs, and ate meat from the cattle, sheep and goats they raised. Prickly pear hedges provided nopales to eat and formed fences to keep the livestock out of the fields.

To lighten their work, the Castros had oxen and mules to plow the fields, barns for storage and livestock shelter, and fields of wheat, corn, beans and potatoes.

The house, with sweeping eastward views, offered plenty of room for fiestas and overnight guests. The adobe overlooked the road from Jose Amesti’s redwoods to the Castro embarcadero (wharf or landing), where lumber was shipped out. The adobe was built one room deep, so the sunshine could penetrate the rooms from two sides brightening the otherwise somewhat dark, cool rooms.


Brick Making

In 1989, the Castro Adobe was seriously damaged by the Loma Prieta Earthquake, ending its use as a private residence. The north cocina wall was severely damaged in the earthquake and careful evaluation concluded that the wall must be reconstructed. Many adobe bricks were needed to complete the reconstruction of the wall.

In the summer of 2007, under the leadership of Friends board members and Project Manager Jessica Kusz, Friends partnered with adobe brick-making expert Tim Aquilar and began the process of making 2,500 bricks, each measuring 14 inches x 28 inches and weighing approximately 85 lbs.

Because it was critical to ensure that the new adobe bricks were compatible with the existing adobe bricks, testing of existing adobe bricks was done to reveal the sand, silt and clay content. After significant research by the project team to identify the right local dirt choice to match the existing adobe bricks, Rick Santee, owner of Santa Cruz County-based Central Home Supply, was selected as the supplier. The first 40 yards of dirt was delivered July 27, 2007.

The brick-making project relied on a force of more than 150 volunteers, aided by California Conservation Corps workers. After being formed, the bricks had to be lightly watered daily to ensure a slow drying process. Neighbors assisted with this task. After about 20 days, when the bricks were stable, the curing process required the bricks to be turned on their sides, an arduous task due to the weight and fragility of each brick. Despite this, among the 2,500 bricks that were produced only 14 percent suffered breakage. The finished bricks were used to restore the adobe.


Located to the west of the adobe, the Potter-Church Garden was constructed from 1968-1972, when the property was owned by David and Elizabeth Potter. The Potters were close friends with landscape architect Thomas Church, who consulted on the design of the garden and provided on-site sketches. Church is significant as the founder of the modern movement in landscape architecture known as the “California Style.” He completed master planning for UC Berkeley, UC Santa Cruz and Parkmerced in San Francisco, as well as countless residential designs. The garden provides a central gathering place for group tours and special events.

Friends restored the garden, following Thomas Church’s original design. The garden was thoroughly researched and analyzed in the report, “Garden Restoration Report for the Potter Garden,” prepared in 2011 by Pam-Anela Messenger, landscape architect and Thomas Church expert. In the report, Messenger detailed the evolution of the garden and identifies significant plant and tree species. She also developed a template and landscape plan to enable restoration of the garden.

The Potter-Church garden is a unique outdoor space created by a landscape architect of national significance. The garden helps tell the story of later owners of the adobe and their stewardship of the site through 1988. Landscape contractor Laura Livingston and landscape designer Kathleen Schaeffer were hired by Friends to restore the Potter-Church Garden. Restoration work included landscaping, paths, drainage and irrigation, lighting, fence and gate repairs. Work was completed in 2015.

Seismic Stability

The second floor is significant for its use during fandangos. For Californios, the fandango was a major social event, at which family and friends danced, played music and enjoyed lavish feasts during the Rancho era. To accommodate visitors, the second floor required stabilization and access improvements.

Restoration architect Tony Crosby and structural engineer Fred Webster worked to increase the load capacity through the installation of a single steel beam in the first-floor rooms that extends the length of each room to support second-story floor joists. The purchase and installation were completed in 2016. To increase access to the second floor, a lift was installed in Summer 2016. The Castro Adobe lift project is considered to be a model for other two-story adobe buildings because the design allows access for all while maintaining the interpretive qualities of the site.


The Castro Adobe cocina (historic kitchen) is significant as one of the few remaining original Rancho cocinas in California. Restoration of the cocina allows visitors to experience daily life at a Mexican rancho, including food preparation in the cocina and women’s roles in Californio culture, as well as overall life at the Castro Adobe including how the family used the building and site.

With expert assistance renowned adobe conservation architect Anthony Crosby and noted structural engineer Fred Webster, restoration work on the cocina included:

  • Archeological investigation of the interior of the cocina, including position and placement of original brasero, as well as investigation of the floor to determine original earthen floor composition and location.
  • Installation of a new roof and historically accurate earthen floor.
  • Painstaking removal of all non-historic latex paint on adobe walls.
  • Fabrication and installation of historically accurate cocina 
  • Construction of a reproduction brasero.
  • Restoration of wall finishes, using mud plaster.
  • Concealment of steel material utilized in seismic upgrade.
  • Final structural stabilization of the north cocina wall and roof system.
  • Installation of electrical service to provide ambient lighting and interpretive exhibits.
  • Development of an Interpretive Plan and installation of interpretive panels.
  • Development of a historically accurate Furnishing Plan and furnishing of the cocina with historically accurate cooking implements, reproduction food items and furniture.
  • Development and implementation of an accessibility plan, including implementation of life safety standards including fire egress.

Restoration work 2020-22

  • A fire suppression equipment system, including a water tank and fire monitoring system, was installed and will make the interior of the building fire-safe. Upstairs, the fire suppression was concealed within a new ceiling.
  • Cracks were repaired, and both the interior and exterior of the building were whitewashed in 2020-22. The floors also were refurbished, and the paint colors around the windows and doors were analyzed and this information was used to restore the interior and exterior finishes.
  • Experts spent much of fall 2021 restoring two unique elements in the interior of the Castro Adobe: the painted baseboard and chair rail, both of which are original elements of the adobe and are considered fairly rare for this era.
  • New electrical was installed and period-appropriate lighting was put in place.
  • The fandango room wood partition walls were reconstructed. One portion of the original wall remained and this was used as a template to reconstruct the remaining sections of the partition walls.
  • The cocina walls were analyzed and then whitewashed to restore the original finishes to the room.
  • Funded by Proposition 68 funding, A new roof was installed in 2022.
