National Historic Landmark · Spanish Mission Revival Architecture · Frank Miller Legacy · Riverside Civic History
The Mission Inn began in 1874 as Glenwood Cottage, a twelve-room adobe-and-wood boardinghouse built on the site by civil engineer Christopher Columbus Miller as a secondary income for his family. In 1880 his son Frank Augustus Miller (1858-1935) bought the property and began the gradual expansion that would consume the rest of his life.
By 1902, with Riverside flush with citrus money, Frank Miller had secured financing from Pacific Electric magnate Henry E. Huntington and retained architect Arthur Burnett Benton. Benton's first major addition — the Mission Wing in Spanish Colonial Revival style — opened in 1903. The Cloister Wing, with its music room and Carmel Dome, followed in 1911. Subsequent wings, towers, and the underground catacombs filled out the block over the next two decades, with Frank Miller traveling the world to bring back art, artifacts, and architectural fragments to embed in the building.
Frank Miller died on June 17, 1935; the city of Riverside paused for fifteen minutes to mark the moment. The hotel passed to family hands and then through several twentieth-century ownership arrangements before its current operation. It was designated a National Historic Landmark in 1977.
The catacombs — a network of tunnels and chambers running beneath the property — were a signature element of Miller's construction program. They are not part of general guest access; the only public entry is via the Daily Historic Tour, which departs twice daily from the lobby.
Sources
The story that has followed the Mission Inn for decades involves sound rather than sight. A former employee recalled an older gentleman who had been placed in an upper floor room — the only guest on the floor due to construction elsewhere in the hotel. When asked the next morning whether his accommodations were adequate, the man said everything was fine, especially the woman singing beautifully in the adjacent room.
Alice Miller Richardson — Frank Miller's sister, who managed the hotel alongside Frank and continued after his 1935 death until her own in 1938 — is the name attached to that account. Her fourth-floor room in the southeast corner of the building is the most consistently cited paranormal location. Guests and staff have reported cold spots, cold physical contact, and apparitions of a woman in period clothing. The singing is the account that recurs most distinctly.
Frank Miller's room in the northeast corner of the same floor has its own pattern of reports — cold zones, unexplained sounds, flickering lights — though less centered on a specific manifestation.
The catacombs present a different category of experience. The tunnel network, accessible only via the guided tour, has produced reports of disembodied voices and footsteps, along with sightings of a figure in what witnesses describe as monastic robes. Paranormal investigation teams using EMF meters and EVP equipment have visited the tunnels; the specific results of those sessions are described in general terms in available sources rather than with precise data.
Guests across the building have also described being physically touched or pushed, cell phone failure in specific corridor sections, and floating blue lights in the courtyard areas.

The Mission Inn's 238 one-of-a-kind guest rooms include the fourth-floor rooms associated with Frank and Alice Miller, both of whom are reputedly still in residence. Guests in upper-floor rooms have reported hearing a woman singing beautifully in an adjacent room — and later learning the floor was otherwise unoccupied. The hotel features ornate fireplaces, reading nooks, and stained-glass windows throughout.
A 55-minute guided tour with exclusive access to the catacombs — the tunnel network beneath the hotel running toward Mt. Rubidoux — along with hidden passageways and rare historical artifacts. The catacombs are closed to general access; this tour is the only way in. Visitors have reported disembodied voices and the apparition of a monk in the tunnel sections.

Long Beach, CA
The RMS Queen Mary was constructed at John Brown & Company's Clydebank shipyard beginning in 1930, launched September 26, 1934, and sailed her maiden voyage on May 27, 1936. Requisitioned as a troopship in 1939, she carried 810,000 soldiers under the nickname 'The Grey Ghost.' The ship has been permanently moored in Long Beach, California since December 1967.
Galveston, TX
Grand Galvez, originally Hotel Galvez, opened in 1911 as part of Galveston's recovery from the catastrophic 1900 hurricane. The Spanish Colonial Revival landmark on Seawall Boulevard is the only historic beachfront hotel on the Texas Gulf Coast and now operates as part of Marriott's Autograph Collection.
Eureka Springs, AR
The 1886 Crescent Hotel was built as a luxury Victorian resort atop the Ozark mountains of Eureka Springs, Arkansas, then briefly operated as a women's college before its most notorious chapter: Norman Baker's fraudulent cancer clinic from 1937 to 1940. Baker charged dying patients for treatments that offered no medical benefit, and the hotel retains his intact basement morgue.
