Gold Base is the confidential de facto international headquarters of the Church of Scientology. It is located at 19712 Gilman Springs Rd,
San Jacinto in Riverside County, California and about 100 miles from Los Angeles. The heavily guarded compound comprises about 50 buildings surrounded by high fences topped with blades and watched around the clock by patrols, cameras and motion detectors. The property is bisected by a public road, which is closely monitored by the Church with cameras recording passing traffic.
The Church of Scientology acquired the property, which had formerly been a resort called Gilman Hot Springs, in 1978. It had previously been a popular Inland Empire vacation spot and spa established in the 1890s but went bankrupt in the late 1970s due to changes in American vacation habits.
