Chateau Scientology.

Franklin Avenue, skimming past the mouths of Hollywood's eastern canyons, at the disappearing far-north edge of city maps, forms a halfhearted high street for the apartment dwellers clustered on its banks. Public life happens in the Mayfair grocery store, and in a block-long stretch of sidewalk cafes and used-book stores. The apartment buildings are old, and in some cases beautiful, like the Villa Carlotta, a late-nineteen-twenties Mediterranean-style structure designed by Arthur Harvey, where the architect Wallace Neff lived for many years.

Across from the Villa Carlotta is the avenue's defining anomaly: a monumental turreted castle, also designed by Harvey, on a three-acre site, with formal gardens, a bubbling stream, a tennis court, and a pair of rubber trees that are more than a hundred years old. Seven stories tall, the castle is an overgrown folly the color of farm cream, with swaying long-necked palms that seem to graze its roofs. "You want to circle the block and look at it," Richardson Robertson III, a local architect, says. "It's unusual in the modern-box world we live in to see so many nooks and crannies and little windows and interesting roof lines." Built as the Chateau Elysee, a long-term residential hotel for movie stars, it is considered by preservationists to be one of the city's grandest Norman-revival buildings. (The Chateau Marmont is smaller and sits on considerably less land.) Since 1973, the Chateau Elysee has been owned by the Church of Scientology, which calls it Celebrity Centre.

Scientology, the religion that grew out of L. Ron Hubbard's popular self-help manual "Dianetics: The Modern Science of Mental Health," incorporates aspects of Eastern philosophy, management theory, and science fiction--a genre in which Hubbard was prolific. The first Scientology church was established in downtown Los Angeles, in 1954. Although the Church's spiritual headquarters are in Clearwater, Florida, and it has facilities around the world, Scientology is most deeply associated with Los Angeles and its entertainment industry. The dozens of local buildings owned by the Church, many of them historically significant and now prominently marked with posters advertising "Dianetics" or with the eight-pointed cross that serves as one of Scientology's symbols, have entered the landscape of iconic L.A. architecture as a visually stimulating mash of old Hollywood and seventies-style art direction and signage. At Celebrity Centre, where a large yellow sign affixed to a south-facing roof overlooking the 101 Freeway announces the building and its owner, this juxtaposition is especially acute. Diane Kanner, an architectural historian who specializes in twentieth-century Los Angeles, calls the building Chateau Scientology.

From the outset, the conversion of celebrities was important to Scientology. An internal newsletter produced by the Hubbard Communications Office, probably in the mid-fifties, asserts, "There are many to whom America and the world listens. On the backs of these are carried most of the enthusiasms on which the society runs." It goes on, "It is obvious what would happen to America if we helped its leaders to help others. Project Celebrity is part of that program. It is obvious what would happen to Scientology if prime communicators benefitting from it would mention it now and then." The piece concludes with a list of the day's stars--Orson Welles, Howard Hughes, Walt Disney, and Greta Garbo among them--referring to them as "game" and "quarry" for Scientologists to "hunt." Though Scientology is not known to have had success with this early group, the movement now counts Tom Cruise, John Travolta, Kirstie Alley, and many other celebrities as members.

Celebrity Centre is used for Scientology courses and for "auditing," a mainstay of the religion, in which a person undergoes a guided talk-therapy session, usually while holding a device known as an E-Meter, which is supposed to measure one's spiritual state. The goal is to eliminate "mental image pictures" associated with traumatic events; when a person is "Clear"--freed of all such associations--he can advance to the mystical and esoteric levels of Scientology. The path to becoming an "Operating Thetan," or pure spiritual being ("thetan" being Hubbard's word for the soul), is laid out in a table called "The Bridge to Total Freedom: Scientology Classification Gradation and Awareness Chart of Levels and Certificates." Scientology is a technological religion and claims to have developed "exact, precise methods to increase man's spiritual awareness and capability." Completion of the Bridge takes years, and each stage requires a cash investment. An initial twelve-and-a-half-hour auditing session costs between six and seven hundred dollars, Greg LaClaire, a vice-president of Celebrity Centre, says. (Aspiring Scientologists can mitigate the expense by choosing to be audited by a fellow initiate rather than by a staff member.) In the Holiday 2007 Dianetics and Scientology catalogue, a deluxe Planetary Dissemination Edition E-Meter--billed as a "tool for Golden Age of Tech certainty," to assist in "faster progress up The Bridge"--was offered, in "Diamond Blue," for five thousand five hundred dollars.

On Celebrity Centre's upper floors, there are thirty-nine hotel rooms to accommodate visiting Scientologists. An undated leaflet advertising "a safe environment for Celebrities and Scientologists" contains a plug from Travolta: "Good rest, good food, good service but most of all I felt very safe in this space"; Celebrity, a magazine produced by Celebrity Centre, which features a Scientology celebrity on the cover of every issue, urges readers to stay at the hotel for five to six weeks "to complete your Basics books & lectures courses faster!" In the basement, there's a drug detox facility. The castle also fosters a feeling of community. "Hollywood's not a very easy industry to bust into," Hilary Royce, a former dancer who went to Sarah Lawrence and is now the director of community affairs for the Church of Scientology International, told me. "Any artist at Celebrity Centre would tell you it's a safe place to study scripts, to network. It's really a hub."

The promise of connectedness attracts many Hollywood hopefuls. Celebrity Centre offers a range of Success in the Industry Seminars--Breaking Into Commercials, How to Get Cast in the Pilot Season, Hollywood Acting Class--which it promotes with flyers posted at auditions around town. A former actor I spoke with told me that when he first got to Hollywood, a decade ago, he went to Celebrity Centre for what "seemed like a legitimate industry workshop," only to find that "it was more or less an opportunity for them to solicit people."
