Arkham Penitentiary

A place to house the clinically insane who do not meet the requirements for being placed within intensive treatment. Aside from Arkham Manor, this is the largest building on Arkham Island, housing the most inmates and requiring the most staff. A dull, dreary building with gothic styled architecture built by the Arkham family when it first settled in Gotham City. Decorative gargoyles line even the insides of the building. For the inmates, the rooms are made of one of three materials, depending; plexiglass, brick, or fence. On the west side of Arkham Island, this is the best spot to get a view of Gotham City just a few miles across the bay.
