ADX FlorenceSupermax
The highest level of prison security. These prisons were designed to house the most dangerous of inmates. These include serial killers, inmates who have committed murders in less secure prisons, and high-profile inmates such as
Theodore Kaczynski, Terry Nichols, and (formerly) Timothy McVeigh.The United States Federal Bureau of Prisons operates two such facilities: USP (United States Penitentiary) Marion, formerly a Level 5 facility, and ADX Florence, which was built specifically as a supermax facility. Utilizing a penal construction and operation theory known as the "control unit" prison, the conditions of these facilities are extremely harsh — excessively so to some human rights watchdog organizations. Inmates generally spend 23 or more hours per day in their cells, with the additional hour spent either in a supervised one-man shower, or in an "outdoor" recreation area, generally a solid-walled pen twice the size of a cell and also used in solitary.
The cells themselves in ADX Florence are also designed to minimize social contact and increase isolation from the outside world. The cells, usually 7x12 feet are constructed with solid "boxcar" doors, i.e., with no windows and a locked food "wicket", and are nearly completely soundproofed. Drains and drainpipes leading to the cells, which in USP Marion were used as a method of communication, are routed to a central location and damped. Telephone privliges are virtually non-existent, as is any access to radios and television, and all mail save pre-announced legal communications is opened, read, and censored. There are no visitations of any kind, excepting legal visits. To complete the isolation, the windows of the cells (if existent) are very small and designed to only show the sky.
