CA-179-180 Castro Breen Adobe and Plaza Hotel

Marker text: CASTRO/BREEN ADOBE AND PLAZA HOTEL

The Castro/Breen adobe is associated with the early development and settlement of Mexican California. The adobe is an excellent example of blended eastern and western building methods first produced in Monterey to form the Monterey Colonial architectural style. The adobe served as headquarters and residence to Jose Antonio Castro, Commandant General of Alta California, and later to Donner Party survivors Patrick Breen and family.

The Plaza Hotel originated as a one-story adobe barracks and two-story guardhouse for soldiers protecting Mission San Juan Bautista across the street. After secularization in 1835, the building became a home and general store for the Anzar family. The building was rented and later sold to Italian immigrant Angelo Zanetta who added a wooden second story and opened the Plaza Hotel in January 1859. The hotel became noted for its fine cuisine and liquors. In the 1860s San Juan Bautista became a stop for seven stagecoach lines. The hotel welcomed travelers, business men, and traveling salesmen. When the New Idria quicksilver mine opened just to the southeast, even more patrons frequented the hotel.
