Overview and Facility Profile of Potosi Correctional Center

Potosi Correctional Center opened in 1989 to house maximum-security male offenders. It sits on a substantial land plot in rural Washington County, providing housing, medical care, administrative segregation, and vocational training within a hardened perimeter defense system.

Historically, PCC was notable for housing Missouri’s death row offenders and operating the state’s execution chamber. However, capital punishment operations and the housing of condemned inmates were relocated to the Eastern Reception, Diagnostic and Correctional Center (ERDCC) in Bonne Terre, Missouri.
