A lowly house near Camelback Mountain in Phoenix, Arizona, once the home of L. Ron Hubbard, the founder of the Scientology religion, has been restored by the Church of Scientology to exactly how it was in 1952, when Hubbard made his breakthrough discoveries into the spiritual nature of man. Here's an article about the L. Ron Hubbard House in the East Valley-Scottsdale Tribune, with photos.
The Church of Scientology has also recently renovated homes Mr. Hubbard occupied in South Africa in the early 1960's, and in Washington, DC in the mid 1950's. These basically serve as museums of the history of Dianetics and Scientology around the world.
I've toured Hubbard's mansion in East Grinstead, Sussex, England, which is within walking distance of the Scientology college he established there in East Grinstead. From that tour, I recall a basement room which had been made into a recording studio and lecture hall that might hold 50 people. It was here that Hubbard recorded some lectures that I found particularly inspiring. It wouldn't mean much to most people, but it was significant to me.
