Rancho Los Alamitos in present-day Long Beach preserves a layered history that begins with Povuu’nga, a Tongva village and major ceremonial and trade center inhabited from at least 500 CE into the late 18th century. Part of the original Rancho Los Nietos grant of 1784, it became a separate property in 1834, then passed to Abel Stearns in 1844 and served by the early 1850s as headquarters for a vast cattle operation supplying the Gold Rush. Later developed by the Bixby family for agriculture and oil-era wealth, the surviving adobe house, barns, and gardens now form a museum interpreting Indigenous, Spanish, Mexican, and American eras.
