Through its museum services, educational programs, and outreach initiatives, Mission Inn Hotel maintains, interprets, and promotes the cultural history of the Mission Inn, Riverside, and the other southern California communities. Exhibitions at the Mission Inn Museum explore the hotel's past and long-lasting effects on the Riverside neighborhood and beyond. From the time when the Mission Inn Hotel first opened as an adobe boarding house in 1876 to the present, the museum's collection is important in illustrating the stages of its evolution. The original owner and developer of the Inn, Frank Miller, was an early supporter of the Mission Revival movement, an enthusiastic collector of art from all over the world, a fan of aviation, an inventive thinker, a master of marketing, and a fervent supporter of the local neighborhood. The museum has a wide range of topics to examine in its rotating exhibitions thanks to Miller and his family's significant contribution to Riverside's development and the Mission Inn's position as a focal point of Riverside civic life for more than a century.
