The Camarillo Ranch was originally a 10,000 acre Spanish land grant created in 1837, patented to Gabriel Ruiz in 1866, then purchased by Juan Camarillo in 1875. His son Adolfo built the Queen Anne Victorian home in 1892. Later the barn and stables were added to support the agricultural work and house the renowned Camarillo White Horses. Today the ranch is owned by the City of Camarillo and operated by the non profit Camarillo Ranch Foundation.
