The Ygancio Palomares Adobe, built between 1850 and 1855, was once the center of the sprawling 22,000-acre (89 km2) Rancho San Jose. The Rancho San Jose consisted of land taken from the Mission San Gabriel in 1834 as part of the Mexican government’s secularization decree. In 1837, Mexican Governor Juan Bautista Alvarado granted the land to Ygnacio Palomares and Ricardo Vejar, both sons of native Spaniards. The Rancho San Jose operated by Dons Palomares and Vejar covered land that now forms the communities of Pomona, LaVerne, San Dimas, Diamond Bar, Azusa, Covina, Walnut, Glendora, and Claremont. Palomares initially lived in the “Casa Primera”, an earlier adobe which is also operated by the Historical Society of Pomona Valley.
