Luister naar ADX Florence: The U.S.’s Most Secure Prison

ADX Florence, built south of Florence Colorado in 1994, is the most secure prison in the United States prison system. Commonly referred to as a “Supermax” prison, it has 490 beds in a compound which encompasses 37 acres. The prison was designed to house prisoners deemed too dangerous or high-profile for regular incarceration, and nearly 95% of all inmates that have been sent to Florence were transfers with histories of violent behavior in other prison facilities.
