Casa Blanca Inn: The Onion-Domed Resort Where Marilyn Monroe Wintered

A 1920s desert mansion turned Moroccan-fantasy resort: George Borg crowned it with an onion dome in the 1940s, hotel operators opened it as the Casa Blanca Inn in 1953, and for three decades Marilyn Monroe, Clark Gable and Eisenhower-era society dined at the Sultan's Table — until the 1980s converted it all to a gated community that kept the dome as a clubhouse.

The 30-second version

  • The core house was designed and built in the 1920s by R.T. 'Bob' Evans — of the Jokake adobe dynasty — as a home for the Donald Kellogg family.
  • Borg-Warner industrialist George Borg bought it in 1944, renamed it Casa Blanca, added the iconic onion dome, cottages, gardens, stables and even an airstrip.
  • Hotel management converted it to a resort in 1953; a 1958 sale expanded the resort and platted surrounding residential lots.
  • Its celebrity ledger ran deep — Marilyn Monroe, Clark Gable, Charlie Chaplin, Betty Grable and President Eisenhower all passed through — with the domed Sultan's Table restaurant as the showpiece.
  • The resort wound down in the early 1980s and was converted to today's gated Casa Blanca community; the dome survives as a private landmark.

What was the Casa Blanca Inn?

Of all the corridor’s lost resorts, the Casa Blanca Inn had the strangest silhouette and the best guest book. Its bones were pure Scottsdale aristocracy: a 1920s desert mansion built by R.T. “Bob” Evans — the master adobe builder of the Jokake dynasty — for the Donald Kellogg family, out on McDonald Drive when McDonald Drive was a dirt promise.

The fantasy arrived in 1944 with George Borg, the Borg-Warner industrialist, who bought the estate, renamed it Casa Blanca, and did the thing everyone remembers: crowned the living room with a gleaming onion dome — by most tellings, partly so his wife, an avid pilot, could spot home from the air. He added guest cottages, gardens, stables, a pool and an airstrip, entertaining at a scale that made conversion almost inevitable: in 1953 hotel management took over, and the Casa Blanca Inn opened for business.

Three decades of high glamour followed. The domed room became the Sultan’s Table, the Valley’s most exotic dining room, and the register filled with the era’s brightest names — Marilyn Monroe, Clark Gable, Charlie Chaplin, Betty Grable, President Eisenhower — stars who wanted Camelback-corridor discretion with a little theater attached.

The ending was the corridor’s gentlest: no wrecking ball, but a slow 1980s conversion into today’s gated Casa Blanca community — which, almost uniquely in this archive, kept the landmark. The dome still floats above the hedges on McDonald Drive.

Why Casa Blanca mattered

It was the corridor’s fantasy pioneer. Decades before the Montelucia built its Andalusian village a mile east, Casa Blanca proved the Valley would pay for transportive theater — that a Moroccan dome in the Sonoran wasn’t kitsch but magnetism. Every themed dining room and fantasy resort in the market descends from the Sultan’s Table’s insight.

It ran the mansion-to-resort pipeline. The Valley’s early luxury stock was private estates; Casa Blanca showed how they became hospitality — the same path as Lon Megargee’s Casa Hermosa (now the Hermosa Inn) and, at grander scale, the pattern by which Paradise Valley’s playgrounds opened to paying guests. Its 1958 expansion-plus-subdivision also previewed the resort-real-estate hybrid that master-planned Scottsdale later industrialized.

Its celebrity era defined PV discretion. Monroe and Gable didn’t come for the dome; they came because Paradise Valley’s estates-and-inns geography let famous people be unphotographed. Casa Blanca institutionalized that promise a generation before Sanctuary turned it into a brand.

It’s the rare lost resort you can still glimpse. The dome survives inside the gated community that succeeded the inn — the corridor’s best drive-by history moment. The full pilgrimage: dome sighting on McDonald, then dinner at El Chorro, the one neighbor from Casa Blanca’s world still pouring.

Dome economics: how the fantasy paid, then stopped paying

Casa Blanca’s arc maps the corridor’s midcentury economics with unusual clarity. Act one — Evans-built mansion, 1920s — represents the pre-resort accumulation phase, when the corridor’s best sites were claimed by private wealth (Kelloggs here, Megargee’s patrons nearby) attracted by the same light and mountains the inns would later retail. Act two — Borg’s 1944–53 estate era — is the war-fortune influx: industrial money (Borg-Warner’s aviation and automotive profits) buying Arizona fantasy at a scale that blurred home and hotel. The dome itself is the era’s perfect artifact: engineering wealth expressed as Arabian Nights whimsy, with an aviation-age justification attached.

Act three, the 1953–82 resort era, ran on a formula the market has since forgotten: small, strange and social. Casa Blanca never had the room count of the Safari or the golf of Mountain Shadows; it competed on atmosphere density — the Sultan’s Table’s costumed exotica, the gardens, the sense of dining inside an eccentric millionaire’s imagination (because you were). The 1958 restructuring — management and contractors buying Borg out, expanding the inn while platting home lots around it — monetized the glamour twice, using the resort’s cachet to sell the neighborhood, Ingleside’s old play in a fez.

The ending followed the subdivision logic to its conclusion. By the late 1970s, the corridor’s economics had inverted: Paradise Valley land under a small seasonal resort was worth vastly more as estate lots, and the town’s residential-first politics (the same forces that would later grind through the Mountain Shadows redevelopment wars) favored conversion. Through the 1980s, architect George Christensen guided the transformation into the gated Casa Blanca community — additions and new residences around the preserved dome, the Sultan’s Table’s room repurposed as communal centerpiece.

That preservation deserves the final note. The corridor’s other fantasies died totally (La Posada’s grotto bar exists nowhere but memory); Casa Blanca’s conversion kept the icon, privately but physically. It suggests the counterfactual gentler ending the whole lost-resort archive could have had — and it means that on McDonald Drive, uniquely, the fantasy era still has a rooftop: one onion dome, catching the sunset above the hedges, sixty years after Monroe checked out.

The Casa Blanca Inn timeline

    George Borg of Borg-Warner buys the estate, renames it Casa Blanca, and crowns the living room with the onion dome — a beacon for his aviator wife.

  3. 1953

    Borg hands the property to hotel management; the Casa Blanca Inn opens its resort era.

  4. 1958

    The management company and partners buy the resort, expanding it and platting the surrounding land as a residential community.

  5. 1950s–60s

    Peak glamour: Monroe, Gable, Chaplin, Grable and Eisenhower among the guests; the Sultan's Table becomes the Valley's most exotic dining room.

  6. early 1980s

    The resort era ends; conversion to a gated residential community proceeds through the decade with architect George Christensen's additions.

  7. Today

    The Casa Blanca community holds the site; the dome survives as its centerpiece — a private monument to the corridor's fantasy era.

Questions people actually ask

Was Casa Blanca Inn a real resort or just a mansion?

Both, in sequence: a 1920s private mansion (built by R.T. Evans for the Kellogg family), then George Borg's estate from 1944, then a genuine resort from 1953 — cottages, pool, stables, gardens and the Sultan's Table restaurant — through the early 1980s.

Did Marilyn Monroe really stay at the Casa Blanca Inn?

She's among the guests consistently cited in accounts of the resort's 1950s–60s heyday, alongside Clark Gable, Charlie Chaplin, Betty Grable and President Eisenhower. The inn was precisely the kind of discreet, glamorous hideout that era's stars favored in the Valley.

Why does a Paradise Valley resort have a Moroccan dome?

George Borg added the onion dome above the living room after buying the estate in 1944 — by most tellings partly as a landmark his wife, an avid pilot, could spot from the air. It gave the later resort its exotic identity and its Sultan's Table restaurant.

Does the Casa Blanca dome still exist?

Yes — when the resort was converted to a gated community in the 1980s, the domed building was preserved and remains the community's centerpiece, glimpsable from McDonald Drive. It's one of the few physical survivors of the corridor's lost-resort era.

Where exactly was the Casa Blanca Inn?

On McDonald Drive near Invergordon Road, on the Scottsdale–Paradise Valley border — today's Casa Blanca gated community, a few minutes from El Chorro and Camelback Inn.
