The Mission Inn Foundation was incorporated in 1976 to assist in the preservation and restoration of the Mission Inn, and originally, to assist in managing the hotel during ownership by the City of Riverside. The Mission Inn hotel is now privately owned by Mr. Duane Roberts, and the Foundation has a unique role of operating a non-profit museum within an operating for-profit hotel. The Mission Inn Museum was opened in 1993, simultaneous with the reopening of the Mission Inn hotel after extensive renovations. The Mission Inn Foundation operates the Mission Inn Museum. The museum’s collection is significant in demonstrating the epic periods of Mission Inn development. Frank Miller, the original owner and developer of the Inn, was an early proponent of the Mission Revival movement, an avid collector of art from around the world, an original thinker, a marketing genius, and a strong community booster. Miller’s central role in the development of Riverside and the forging of a community identity gives the museum a broad range of suitable interpretive topics.
