José Castro House  Jose Castro House, now known as the Castro-Breen Adobe, in San Juan Bautista, California, USA, is a historic Monterey Colonial adobe home built by José Antonio Castro in 1840. Castro was Commandant General of Alta California. In 1848 Castro sold the house to Patrick Breen, survivor of the ill-fated Donner party of 1846, and the Breen family lived in the house until 1935. They sold it to the State of California who adapted it as a museum and incorporated it into the San Juan Bautista Plaza Historic District. José Antonio's father José Tiburcio Castro was a soldier, member of the "diputacion" (Alta California legislature), administrator of Mission San Juan Bautista after it was secularized, and grantee of Rancho Sausal. The elder Castro used his position to obtain land grants for relatives and friends. His son was granted land on the San Juan Bautista plaza, where he built an adobe house in 1841. Jose Antonio Castro used the house as an administrative base for his military operations (soldiers' barracks were next door) and let his secretary use it as a residence. The house, also known as the Castro-Breen Adobe, is a two-story Monterey Colonial-style adobe, and includes the characteristic 2nd-story full-length covered porches on both long sides. The style of architecture originated in California, blending Spanish colonial architecture with New England style. Massachusetts native Thomas O. Larkin built the first known Monterey-style house in 1835 in Monterey, California. Adding a wood frame in the adobe walls allows for more windows than traditional adobe construction, and can support a second floor. In the Monterey style, the porches and extended roof eaves protect the adobe bricks and outer shell from water damage. The pane glass windows beside the front door of the José Castro House are not typical of Monterey architecture and reflect the influence of Greek Revival architecture, which was also popular in the mid-19th century. Today, the José Castro House property includes a half-acre orchard and garden. San Juan Bautista State Historic Park uses the José Castro House as a fully furnished museum, where visitors are welcome to explore and see what the inside of the house looked like in the mid-19th century. Several other historic buildings in the plaza that are part of the San Juan Bautista Historic District are also open to the public.
