"The Hole" is the name of a detention building—also known as the SP Hole, the A to E Room, or the CMO Int trailers—operated by the Church of Scientology on Gold Base, a private compound near the town of Hemet in Riverside County, California. Dozens of its senior executives have been confined within the building for months or years. It consists of a set of double-wide trailers within a Scientology compound, joined together to form a suite of offices which were formerly used by the Church's international management team. According to former members of Scientology and media reports, from 2004, the Church's leader David Miscavige sent dozens of senior Scientology executives to the Hole. The Tampa Bay Times described it in a January 2013 article as:a place of confinement and humiliation where Scientology's management culture—always demanding—grew extreme. Inside, a who's who of Scientology leadership went at each other with brutal tongue lashings, and even hands and fists. They intimidated each other into crawling on their knees and standing in trash cans and confessing to things they hadn't done. They lived in degrading conditions, eating and sleeping in cramped spaces designed for office use.

Gold Base is the de facto international headquarters of the Church of Scientology, located north of San Jacinto, California, United States, about 85 miles (137 km) from Los Angeles. The heavily guarded compound comprises about fifty buildings surrounded by high fences topped with blades and watched around the clock by security personnel, cameras and motion detectors. The property is bisected by a public road, which is closely monitored by Scientology with cameras recording passing traffic.
