The first land grant in what is now Riverside County was given to Juan Bandini in 1838. His area was called El Rancho Jurupa. His daughter married a man named Abel Stearns . Her father gave him a great portion of the rancho. Located at 270 E. Agua Mansa Rd.
Collection includes farm implements, photographs, and memorabilia of local families.
Another portion of the land not owned by Stearns was later sold to another man, Louis Robidoux. The spelling is now accepted as Rubidoux. Louis and all the other ranchers were successful with their businesses and ruled the area. In 1846, Louis Robidoux built the first grist mill in the region. The mill provided flour, a popular but scarce commodity, for settlers and American troops.
