Folsom Prison is California's second-oldest prison, dating back to 1880. In the decades following the Gold Rush, it housed some of the state's most notorious prisoners in stone, dungeon-like cells behind solid-metal doors; was the first prison with electric power; and for many years provided labor for various state projects, including construction, fabrication, and printing of license plates. Thrust into the public consciousness in the 1960s by high-profile performances from country music's Johnny Cash, the prison remains a notorious and legendary institution. The variety of offenders housed at Folsom are incarcerated for a large gamut of criminal behavior, and the California Department of Corrections has been dedicated to rehabilitation efforts throughout the facility's long history.
