Peña Duro, is an infamous prison located in Santa Prisca, a Caribbean country in the DC Comics universe. It was where the Batman villain known as Bane was born and raised. Inmates of the prison were also used as test subject for the steroid Venom.


Referred to by many of its inmates as the armpit of the Earth, Peña Duro was a prison island used to house Santa Prisca's most dangerous criminals. Many considered it as the world's most dangerous prison.

Bane was born here to serve the life sentence of his father, and his childhood was spent behind its hellish walls. Though imprisoned, Bane's natural abilities allow him to develop extraordinary skills within the prison's walls. He read as many books as he could get his hands on, built up his body in the prison's gym, and learned to fight in the merciless school of prison life. Despite his circumstances, he appears to have found teachers of various sorts during his incarceration, ranging from hardened convicts to an elderly Jesuit priest, under whose tutelage he apparently receives a classical education. It is here he commits his first murder at the age of eight, stabbing a criminal who wanted to use him to gain information about the prison. During his years in the hellish prison, Bane carried a teddy bear he calls Osito (Spanish for "little bear"), whom he considered his only friend. It is revealed that Osito has a hole in his back to hold a knife that Bane used against anyone who bullied him.

Bane ultimately establishes himself as the "king" of Peña Duro. The prison's controllers take note and, eventually, force him to become a test subject for a mysterious drug known as Venom, which had killed all other subjects. It nearly killed him at first, but he survives and finds its effects enhance his physical strength. Years later, Bane escaped Peña Duro, along with several accomplices: Trogg, Zombie, and Bird.
