The United States Penitentiary, Administrative Maximum Facility (USP Florence ADMAX), commonly known as ADX Florence, 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. 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. ADX Florence forms part of the Federal Correctional Complex, Florence (FCC Florence), which is situated on 49 acres (20 hectares) of land and houses different facilities with varying degrees of security, including the United States Penitentiary, Florence High. ADX Florence was commissioned when the Federal Bureau of Prisons needed a unit designed specifically for the secure housing of those prisoners most capable of extreme violence toward staff or other inmates. As of January 2023, there are a total of 322 inmates housed. 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 low staff–inmate ratios.
