The Texas State Penitentiary at Huntsville and the Allan B. Polunsky Unit in Livingston are two famous prisons in Texas. The Huntsville Unit, which opened in 1849, is the oldest state prison in Texas. The Polunsky Unit houses Texas's death row inmates.
The Huntsville Unit houses the State of Texas execution chambers. As of December 2015, Huntsville has executed 528 prisoners, the most of any prison in the United States. Famous inmates at Huntsville have included rapper Chad "Pimp C" Butler and Duane "Dog the Bounty Hunter" Chapman. Mother Jones named the Polunsky Unit the second worst prison in the United States. It is notorious for its poor conditions for prisoners and was a setting in the crime fiction novel "Blow Fly" by Patricia Cornwell.
