Colorado State Penitentiary

Colorado State Penitentiary (commonly abbreviated CSP) is a Level V maximum security prison in the U.S. state of Colorado. The facility is part of the state's East Cañon Complex, together with six other state correctional facilities of various security levels.

Description
CSP is located in Fremont County, just east of the county seat Cañon City, Colorado. It is one of 25 prisons in the Colorado Department of Corrections system, and one of seven in and around Cañon City.

The oldest of the seven, originally built in 1871 and predating Colorado's statehood, was the original State Penitentiary. This is the site of Colorado's death row, and the 1929 prison riot. After the 1993 construction of the current facility, that prison was re-dedicated as the medium-security Colorado Territorial Correctional Facility. It is located within the city limits of Cañon City.

Other prisons in the East Cañon Complex include the Arrowhead Correctional Center, the Centennial Correctional Facility, Four Mile Correctional Center, the Fremont Correctional Facility, and Skyline Correctional Center, all nearby in unincorporated Fremont County. The Colorado Women's Correctional Facility near Cañon City in unincorporated Fremont County was decommissioned on June 4, 2009.

Today CSP houses some of Colorado's most dangerous, most violent and most disruptive prisoners. It also holds the state's lethal injection chamber for execution of the death penalty. The prisoners with death sentences are held on "death row" at Sterling Correctional Facility.

All inmates at Colorado State Penitentiary are held in solitary confinement, officially termed Administrative Segregation (AdSeg). AdSeg inmates are all held in solitary cells on 23-hour lockdown for their entire sentence. Such conditions have been held to be adverse for prisoners' mental health and can aggravate existing mental problems. CSP allows offenders out of their cells for an hour per day, including yard time.

As of 2011 the prison has 984 prisoners.

Death row
When the Colorado State Penitentiary opened, death row was moved there from the Colorado Territorial Correctional Facility. Colorado has had no physical death row since 2011, when the State of Colorado moved its death row prisoners to the Sterling Correctional Facility. This was done in settlement of a federal lawsuit filed by Nathan Dunlap, a death row prisoner who had complained about the adverse effects of his physical and mental health of the state's lack of outdoor exercise facilities at Colorado State Penitentiary. By state statute, inmates sentenced to death are executed at the Colorado State Penitentiary. Each is held here for the week before a scheduled execution in a separate holding cell located in the execution suite. All prisoners with death sentences are classified as "securest custody level, administrative segregation".

Capital Punishment was abolished by the legislature for any crime committed after July 2020 in Colorado, with the only three men on death row being granted clemency from suffering death by governor Jared Polis.
