The Cooper Regional History Museum is dedicated to preserving and interpreting the history and culture of the communities of Upland, Ontario, Montclair, Mt. Baldy, and Rancho Cucamonga from 1880 to the present day. Once housed at the Cultural Center, it moved to Upland's historic Town Center in April 1998.
Its new home is the Ontario-Cucamonga Fruit Exchange, an Art Modern office built in 1937. The O.K. Fruit Exchange, however, dates back to 1897 when it was formed to coordinate the sales of oranges, lemons, and grapefruit from a dozen local packing houses. When the Exchange closed in the 1960s, the building was used as offices by the West End Board of Realtors and several local attorneys and accountants. Sixty years later it was entirely rehabilitated to become the Cooper Regional History Museum
