San Quentin

San Quentin State Prison is located on 432 acres (1.7 km²) on Point Quentin in Marin County, California, north of San Francisco. San Quentin State Prison was opened in July 1852, and is the oldest prison in California. It was built by inmates who slept on the prison ship Waban overnight during the construction. San Quentin housed both male and female inmates until 1933 when the women's prison at Tehachapi was built. The state's male death row is located at San Quentin, as well as its only gas chamber.
