A pair of double-wide trailers adjacent to the highway were installed to house Scientology's Central Marketing Unit (CMU) and various Golden Era technical facilities, and were later used as the offices of the Commodore's Messenger Org International (CMO Int) and the International Executive Strata (Exec Strata). They have since become known as "The Hole", where up to 100 senior Scientology executives have reportedly been confined in "degrading conditions" since 2004. A building known as "The Spa", which used to be the center of the old spa resort that existed on the property before Scientology acquired it, is now used by the base's Qualifications Division.
