High-security prisons are facilities designed to house the most dangerous and violent offenders. These institutions have strict security measures, including high walls, surveillance cameras, and armed guards, to prevent escapes and maintain order. Inmates in these prisons often have limited access to the outside world and are closely monitored to ensure safety. The primary goal of high-security prisons is to protect society while providing a controlled environment for rehabilitation. Programs may include education and vocational training, but the focus remains on security. Notable examples of high-security prisons include Alcatraz and ADX Florence, which are known for their stringent regulations and isolation of inmates.
