What is the name of the wizarding prison?

The wizarding prison in Harry Potter is called Azkaban.

Azkaban is a fortress prison used by the British Ministry of Magic to hold witches and wizards convicted of serious crimes. It is located on an island in the North Sea and is protected by Dementors, the terrifying beings that feed on hope and happiness.

The prison first becomes especially important in Harry Potter and the Prisoner of Azkaban, when Sirius Black escapes and is believed to be searching for Harry. The story later reveals that Sirius was imprisoned unjustly, showing how fear and unreliable testimony can distort justice in the wizarding world.

Azkaban is often confused with Nurmengard, another prison associated with the dark wizard Gellert Grindelwald. Hogwarts is a school of witchcraft and wizardry, while Gringotts is the wizarding bank in Diagon Alley. After the Second Wizarding War, Dementors were no longer permitted to serve as prison guards.
