Supermax prison

A super-maximum security (supermax) or administrative maximum (ADX) prison is a "control-unit" prison, or a unit within prisons, which represents the most secure level of custody in the prison systems of certain countries.

"Supermax" redirects here. For other uses, see Supermax (disambiguation).

The objective is to provide long-term, segregated housing for inmates classified as the highest security risks in the prison system and those who pose an extremely serious threat to both national and global security.[1]

History[edit]

Australia[edit]

An early form of supermax-style prison unit appeared in Australia in 1975, when "Katingal" was built inside the Long Bay Correctional Centre in Sydney. Dubbed the "electronic zoo" by inmates, Katingal was a super-maximum security prison block with 40 prison cells having electronically operated doors, surveillance cameras, and no windows. It was closed down two years later over human rights concerns.[7] Since then, some maximum-security prisons have gone to full lockdown as well, while others have been built and dedicated to the supermax standard. In September 2001, the Australian state of New South Wales opened a facility in the Goulburn Correctional Centre to the supermax standard. While its condition is an improvement over that of Katingal of the 1970s, this new facility is nonetheless designed on the same principle of sensory deprivation.[8][9] It has been set up for 'AA' prisoners who have been deemed a risk to public safety and the instruments of government and civil order or are believed to be beyond rehabilitation. Corrections Victoria in the state of Victoria also operates the Acacia and Melaleuca units at Barwon Prison which serve to hold the prisoners requiring the highest security in that state including Melbourne Gangland figures such as Tony Mokbel, and Carl Williams, who was murdered in the Acacia unit in 2010.

Brazil[edit]

In 1985, the state government of São Paulo created an annex to a psychiatric penitentiary hospital meant to house the most violent inmates of the region and established the Penitentiary of Rehabilitation Center of Taubaté, also known as Piranhão. Previously, high-risk inmates were housed at a prison on Anchieta Island; however, that closed down after a bloody massacre. At Taubaté, inmates spent 23 hours of a day in solitary confinement and spent 30 minutes a day with a small group of seven to ten inmates. Ill-treatment of inmates occurred on a daily basis, causing major psychological impairment.[10]


Throughout the 1990s, and the early-2000s, Brazil faced major challenges with gang structures within its prisons. The gang Primeiro Comando da Capital (PCC) gained notoriety in the prison system and had new members joining within the prisons. Riots were a common occurrence and the gang culture became uncontrollable, leading authorities to pass the controversial Regime Disciplinar Diferenciado (RDD), a culture founded from disciplinary punishment.[11]

Germany[edit]

Stammheim Prison, in Stuttgart, Germany, opened as a supermax-style prison in 1964, with an additional wing built in 1975 to house members of the far-left militant Red Army Faction. At the time, it was considered one of the most secure prisons in the world.

United Kingdom[edit]

His Majesty's Prison Service in England and Wales has had a long history in controlling prisoners that are high-risk. Prisoners are categorized into four main classifications (A, B, C, D) with A being "highly dangerous" with a high risk of escaping to category D in which inmates "can be reasonably trusted in open conditions."[12]


The British government formed the Control Review Committee in 1984 to allow for regulating long-term disruptive prisoners. The committee proposed special units (called CRC units) which were formally introduced in 1989 to control for highly-disruptive prisoners to be successfully reintegrated. Yet a series of escapes, riots, and investigations by authorities saw the units come to a close in 1998. They were replaced by Close Supervision Centres (CSC).[13] It was reported to hold 60 of the most dangerous men in the UK in 2015. HM Prison Belmarsh has a High-Security Unit that can hold up to 48 prisoners. The prisoners are those of greatest risk of escape, terrorism, radicalising other prisoners or continuing organised crime from within the prison. Belmarsh was Britain's strictest prison in the United Kingdom.[14]
