Sanchez Adobe is a living history site that was occupied from prehistoric Indian times until it became a historic landmark in 1953. Don Francisco Sanchez, owner of Rancho San Pedro, built the Sanchez Adobe between 1842-1846. Constructed from timbers salvaged from a wrecked Spanish ship found on Point San Pedro, Sanchez Adobe’s authentic Monterey architecture is heavily influenced by Spanish design coupled with relics of the Ohlone Indians and Spanish artifacts. During the first century of its origin, the Adobe served as a bordello, hunting lodge, artichoke packing shed, farm laborers’ quarters and a speakeasy during the prohibition era. It is the second-oldest structure still standing in San Mateo County.

Every third Saturday in September, Rancho Day Fiesta celebrates Mexican California during the Rancho Day Fiesta. Enjoy early Californian music and dancers, real rancho food and make it yourself crafts and demonstrations.
