Built in Hamilton County, New York in 1982, Stronghold Administrative Maximum Security Penitentiary (ADX) was the first federal penitentiary in the United States to be designed specifically for dangerous offenders and to meet the special circumstances of paranormal prisoners whose activity must be severely confined. There have been a few other similar "super prisons" constructed in other states: for the most part they have tried to ameliorate Stronghold ADX's more obvious deficiencies, but in the process they have also introduced a few new ones.
Despite their poor record of containing paranormal prisoners, and a growing controversy concerning possible civil rights violations, the ADX series of prisons has been a political success. The program has since been expanded to include non-paranormal violent and predatory inmates. As of 2004, there are seven ADX federal penitentiaries and over 60 ADX-style state facilities, all of which are exclusively for the incarceration of normal humans.
