Blackgate Prison is a maximum-security penitentiary located on one of the smallest islands in Gotham Harbor. It holds all of Gotham City's most wanted criminals in Gotham's history.
Blackgate was mentioned several times during the course but never seen.
Through the Dent Act, all key individuals with known links to the organized crime ring in Gotham City were placed in Blackgate, with no chance of parole. Selina Kyle was imprisoned here following an encounter with John Blake at Gotham International Airport. However, after Bane revealed the truth behind the circumstances of Harvey Dent's death, he used one of the Tumblers stolen from Wayne Enterprises' Applied Science Division to destroy the entrance to the prison. His henchmen then proceeded to release all of the inmates so they could join their regime.
