Located at the corner of Main Street and Mission Inn Avenue, the Mission Inn Museum features exhibitions examining the hotel’s history and lasting impacts on the Riverside community and beyond. The museum’s collection is significant in demonstrating the periods of Mission Inn development from its beginning as an adobe boarding house in 1876 to the present. 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 aviation enthusiast, an original thinker, a marketing genius, and a strong community booster. Miller and his family’s vital role in the development of Riverside as well as the Mission Inn’s place as a center of Riverside civic life for over a century gives the museum a broad range of topics to explore in their revolving exhibitions. The Mission Inn Museum is also the starting point for all docent-led Mission Inn tours and features an extensive museum store with one of a kind products from local artists, unique Mission Inn souvenirs, in addition to a wide selection of books on Mission Inn and local history.
