Azkaban is the horrible wizard’s prison where witches and wizards are incarcerated for their crimes. Located on a tiny island in the freezing waters of the North Sea, Azkaban is not like Muggle prisons that rely on iron bars and heavy security to keep their prisoners in line. After the Dementors defected to Voldemort during his Second Rise the Ministry decided to hand over Azkaban's security to the Goblins.
