ADX Florence

The United States Penitentiary, Administrative Maximum Facility is an American federal prison in Fremont County near Florence, Colorado. It is operated by the Federal Bureau of Prisons, a division of the United States Department of Justice. USP ADX Florence, which opened in 1994, is classed as a supermax or "control unit" prison, thus providing a higher, more controlled level of custody than a maximum security prison. USP ADX Florence forms part of the Federal Correctional Complex, Florence , which is situated on 49 acres of land and houses different facilities with varying degrees of security, including the United States Penitentiary, Florence High.

USP ADX Florence was commissioned as the Federal Bureau of Prisons needed a unit designed specifically for the secure housing of those prisoners most capable of extreme, sustained violence toward staff or other inmates. As of December 2020, there are 359 prisoners. They are confined 23 hours per day in single cells with facilities made of poured, reinforced concrete to deter self-harm, and are under 24-hour supervision, carried out intensively with high staff-inmate ratios. Phones are generally banned, and only limited broadcast entertainment is permitted. After three years in maximum confinement, some prisoners may be transferred to a less restrictive prison. The aim is to encourage "reasonably peaceful behavior" from the most violent "career" prisoners.
