Celebrity HistoryGreat Story

A Riverside hotel that grew from an 1876 boarding-house lineage into a block-scale Mission Revival landmark, restored and reopened in 1992.

The Mission Inn Hotel & Spa traces its history to an adobe boarding house begun by the Miller family in 1876. Frank Augustus Miller purchased the property in 1880 and developed the celebrated Mission Revival complex in phases, beginning with the Mission Wing in 1903 and continuing through 1931. The hotel is a National Historic Landmark and remains a working downtown Riverside hotel, though its ownership status is in transition under a 2026 agreement for sale.

The House Standard

The Truth-O-Meter

Every claim gets rated. A business's own website can never earn "documented."

The Mission Inn has hosted numerous U.S. presidents.
InventedUnverifiablePlausibleDocumented
Plausible

Historical accounts, including a Los Angeles Times feature, report that ten U.S. presidents visited the Mission Inn. This audit did not review guest ledgers or verify a complete presidential roster, and published secondary accounts differ over exactly which presidents should be counted.

The Mission Inn was built as an eighteenth-century Spanish mission or monastery.
InventedUnverifiablePlausibleDocumented
Invented

The Mission Inn began as an adobe boarding house in 1876 and developed as a commercial hotel complex beginning in 1903. Its Mission Revival architecture and historical-art collection do not make it an original Spanish mission or a former monastery.

The hotel contains artifacts directly salvaged from California's Spanish missions during secularization.
InventedUnverifiablePlausibleDocumented
Unverifiable

Frank Miller assembled a broad collection of art, architectural elements, and mission-themed objects, but this audit did not verify item-level provenance establishing that particular artifacts were salvaged directly from individual missions during secularization. Such claims should not be made without collection records.

Documented

Historical reporting identifies the Mission Inn as the site of Richard Nixon and Patricia Ryan's June 21, 1940 wedding. The event should not be dated to 1952 or described as merely a reception without primary supporting evidence.

The House Angle

Why It Survives

The Mission Inn remained in use because Riverside preservation advocates, public intervention, and later private restoration treated it as a civic asset rather than a disposable old hotel. After a period of decline, Duane Roberts bought it in December 1992 and reopened it following a $55 million restoration described by the hotel. The preservation story is still evolving: the inn's current site reports a 2026 agreement for sale to San Manuel Investment Authority, but the audit did not establish whether the transfer has closed.

Frequently Asked

Questions & Answers

Was the Mission Inn originally a Spanish mission?

No. The Mission Inn was never an eighteenth-century Catholic mission or monastery. Its lineage began with an adobe boarding house in 1876, and Frank Miller developed the landmark hotel complex in Mission Revival style beginning in 1903.

When did the Mission Inn in Riverside become a hotel?

The property began as a Miller-family adobe boarding house in 1876. Frank Augustus Miller bought it in 1880, and the first wing of the current Mission Inn complex opened in 1903; later expansions continued through 1931.

Were Richard and Pat Nixon married at the Mission Inn?

Yes. Richard Nixon and Patricia Ryan married at the Mission Inn in Riverside on June 21, 1940. Claims that place their wedding or wedding reception there in 1952 are incorrect.
