Prison de Kara

Built during the early 1800s during the reign of Sultan Ismail bin Sharif, the Kara Prison (AKA Habs Qara) is a vast subterranean prison in Meknes. Its most unusual feature is that it lacked doors and bars, but it’s believed no one ever escaped.

Its inescapability was due to its complex labyrinth-like design. It was named after a Portuguese prisoner who was granted freedom on the condition that he constructed a prison that could house more than 40,000 inmates.
