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). It was built between 1848-1850 by Juan Jose Castro, son of Jose Joaquin Castro, who was an original Juan Bautista de Anza expedition member. Later, Danish-born Hans Hansen purchased the Castro Adobe. Hansen completed many alterations to the building. Subsequent owners made changes as well, each acting as stewards of the historic adobe, including noted adobe conservationist Edna Kimbro and her husband Joe, who purchased the adobe in 1988.

In 1989, the Loma Prieta Earthquake severely damaged the building, rendering it uninhabitable. The cocina north wall and the south wall of the main house were damaged and in need of reconstruction. The Kimbro’s advocacy for restoration of the building resulted in the sale of the property to California State Parks in 2002. In 2007, in partnership with State Parks, Friends of Santa Cruz State Parks managed and funded the construction of 2,500 adobe bricks used for reconstruction and subsequent seismic stabilization.

Friends undertook the restoration of the Castro Adobe in order to preserve and interpret for the public the only remaining building of the Rancho era in the Pajaro Valley.
