Azkaban är för närvarande det enda wizarding-fängelset i Storbritannien
Once the International Statute of Secrecy had been imposed, the Ministry of Magic felt that the small wizarding prisons that existed up and down the country in various towns and villages posed a security risk, because attempts by incarcerated witches and wizards to break out often led to undesirable bangs, smells and light shows. A purpose-built prison, located on some remote Hebridean island, was preferred, and plans had been drawn up when Damocles Rowle became Minister for Magic.
Rowle was an authoritarian who had risen to power on an anti-Muggle agenda, capitalising on the anger felt by much of the wizarding community at being forced to go underground. Sadistic by nature, Rowle scrapped the plans for the new prison at once and insisted on using Azkaban. He claimed that the Dementors living there were an advantage: they could be harnessed as guards, saving the Ministry time, trouble and expense.

Det enda andra fängelse som vi hör om är Nurmengard, men det verkar inte längre användas ett vanligt fängelse.
They say “For the Greater Good” was even carved over the entrance to Nurmengard.’
‘What’s Nurmengard?’
‘The prison Grindelwald had built to hold his opponents. He ended up in there himself, once Dumbledore had caught him.
