Gold Base, which is sometimes just called Gold, refers to the international headquarters for the Church of Scientology. What gets confusing is that there is another org called "Flag," which is called the "worldwide spiritual headquarters" of Scientology. More on that later.

Gold houses the Religious Technology Center, the non-profit established by current church leader David Miscavige to protect L. Ron Hubbard's assets and oversees all trademarks and copyrights for Dianetics and other Scientology course materials.

The building is in a very secluded area of unincorporated Riverside County near Gilman Springs. It's nearly equidistant from San Diego and Los Angeles, California in the desert area just west of the San Bernardino National Forest and Coachella. 

Some people also refer to Gold as "Int" short for International HQ. The church acquired the Gold property in 1978. The one-time vacation resort went bankrupt and sold for an undisclosed sum.

The heavily guarded complex is where Miscavige and other senior members of the organization live and work, and it's also the site of their media production studio, Golden Era Studios. They produce video materials including training films, promotional spots, and lectures.

The land-based leadership for Sea Org is also based at Gold. This is where Leah, as a member of Sea Org's Commodore's Messenger Org, came to know Shelly Miscavige.

Gold is the alleged location of "The Hole," as well. Leah and Mike have referred several times on the show to this place, a complex of double-wide trailers where David Miscavige allegedly sends misbehaving higher-ups for punishment and reprogramming.
