Near this site, Isaac Williams built a large adobe home in 1841 on the 22,000-acre Rancho Chino, which he acquired from his father-in-law Antonio Lugo. The Battle of Chino took place at the adobe on September 26-27, 1846, when 24 Americans were captured by a group of about 50 Californios. Located on the Southern Immigrant Trail to California, the adobe later became an inn and stage stop famous for its hospitality.
