Like its predecessor Gotham State Penitentiary (also known as Gotham Prison), Blackgate Penitentiary is also located in Gotham City, though on a small island in Gotham Bay. Before the early 1990's and the Crisis on Infinite Earths story arc, Gotham State Penitentiary was the main correctional facility used to house non-criminally insane inmates in Gotham City. Those criminals in Gotham who are deemed to be mentally insane are sent to Arkham Asylum. However, sometime during the late 1980's Gotham State Penitentiary was judged uninhabitable and condemned by the organization Amnesty International. Forced to close its doors, following the Crisis the prison was reopened and from that point on known as Blackgate Penitentiary. A short time later Gotham Prison was left unused.
There have been a few instances when all the inmates in Arkham Asylum have had to be moved to Blackgate Penitentiary due to the former being destroyed, one time by Bane. In addition, the inmates remain in Blackgate Penitentiary until a new Arkham Asylum can be built.
Blackgate Penitentiary was erected at some point in the late 19th century on Blackgate Isle. A group of followers of the Religion of Crime set up base in the manor on Blackgate Isle during this period, with goals of conquering Gotham City, only to encounter Jonah Hex and Amadeus Arkham.

Batman: Arkham Asylum
The plot of this game centers around Blackgate Penitentiary having a fire break out inside it, thus forcing most of the prisons occupants to be moved to Arkham Asylum until Blackgate can be repaired. In actuality, the Joker staged the entire fire, in order to gain more henchmen to assist him in his plan, and to fight against Batman should the hero cause any problems. The inmates transferred over from Blackgate are the most numerous and commonly encountered foes in the game, both as ordinary prisoners or subjects that Joker tests with the Titan Compound.
Batman: Arkham City
Blackgate Penitentiary is rumored to still be under construction or at the very least unsuitable for inmates. Throughout the course of the game some of the prisoners within Arkham talk about rumors that Blackgate has been remodeled into a shopping mall, though these rumors are never confirmed or denied and are more than likely just gossip between the inmates. As in the previous game, inmates from Blackgate are the basic foot soldiers to various villains in the game such as Riddler, Two-Face, Penguin, and Joker. Batman is able to converse with and gain information from the Blackgate prisoners, and at one point in the game certain information is essential to continuing the story. A few of the prisoners working for the Riddler have to be interrogated to open up Riddler's Challenge Maps and progress further along the game.
