Background
The United States Penitentiary, Administrative Maximum Facility (abbreviated as USP Florence ADMAX; commonly known as ADX Florence, Florence Supermax, and the Alcatraz of the Rockies) is a United States federal prison for men in Fremont County, Colorado, United States. It is operated by the Federal Bureau of Prisons, a division of the United States Department of Justice. The prison houses some of the most dangerous criminals in the United States. ADX Florence, constructed in 1994 and opened the following year, is classed as a supermax or "control unit" prison, that provides a higher, more controlled level of custody than a regular maximum security prison (or "high security", as it is called in the federal prison system). 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 adjacent United States Penitentiary, Florence High.
