Mira Loma Prison Complex

Around 5,000 people are incarcerated within the walls that surround this square-mile block, west of Lancaster. Mira Loma has a state and a county correctional facility here. The State's confusingly named Los Angeles County prison has a designed capacity of around 1,200 inmates, and generally houses over 4,000. The Mira Loma Detention Center is a Los Angeles County facility that primarily holds immigration detainees for the INS.
