Tamms Correctional Center

The Tamms Correctional Center is a closed Illinois Department of Corrections prison located in Tamms, Illinois. Prior to its 2013 closure, the prison housed people in two sections: (1) a 200-bed minimum security facility, opened in 1995, and (2) a 500-bed supermax facility known as the Closed Maximum Security Unit ("CMAX"), opened in 1998, that housed people defined by the prison leadership as most disruptive and dangerous.

Prior to the March 9, 2011 abolition of the death penalty in Illinois, the State of Illinois executed prisoners via lethal injection in an execution chamber located within the CMAX section of Tamms Correctional Center.Andrew Kokoraleis, the last person to be executed in the state before Illinois suspended its death penalty, was executed at Tamms in 1999.

Prior to Illinois Governor George Ryan's January 11, 2003 commutation of death row sentences, male death row inmates were housed in Tamms, Pontiac, and Menard correctional centers. After the commutations, only Pontiac continued to hold death row prisoners.

As with other supermax prisons, prison reformers advocated for its closing. The Tamms Year Ten campaign was established in 2008 to push for reforms and closure of the prison. Brutal conditions were reported by several Illinois newspapers, the American Civil Liberties Union, and reform advocates. A report by Illinois Department of Corrections validated the claims. In 2010, U.S. District Judge G. Patrick Murphy ruled that inmates must be allowed to challenge their transfer to Tamms at a formal hearing and wrote in his decision that "Tamms imposes drastic limitation on human contact, so much so as to inflict lasting psychological and emotional harm on inmates confined there for long periods."
