San Quentin State Prison

San Quentin State Prison is a California Department of Corrections and Rehabilitation state prison for men, located north of San Francisco in the unincorporated place of San Quentin in Marin County.

Opened in July 1852, San Quentin is the oldest prison in California. The state's only death row for male inmates, the largest in the United States, is located at the prison. It has a gas chamber, but since 1996, executions at the prison have been carried out by lethal injection, though the prison has not performed an execution since 2006. The prison has been featured on film, radio drama, video, podcast, and television; is the subject of many books; has hosted concerts; and has housed many notorious inmates.
