Changuu Island (Prison Island)
Changuu Island, commonly known as Prison Island or Kibandiko, is a small coral islet situated 5.6 kilometres off the coast of Stone Town. Uninhabited until the 1860s, the island served as a detention site for rebellious enslaved Africans and later as a yellow fever quarantine station built by British colonial officials. Today, while famous for its sanctuary of giant Aldabra tortoises, the island's ruined stone prison complex is haunted by dark historical memory and tales of restless spirits.
