Prison Island, also known as Changuu Island, is located off the coast of Zanzibar, Tanzania, and has a fascinating history tied to both its use as a prison and its role in the slave trade.The Island was initially uninhabited, but it came to the attention of the Sultan of Zanzibar, who purchased it in the mid-1800s. The island was strategically located as part of a network of islands used by the Sultan for various purposes. It was originally used as a quarantine station for those suffering from diseases such as cholera and yellow fever, and it also served as a refuge for escaped slaves.

Under the rule of Sultan Seyyid Barghash, the island was developed into a holding facility for prisoners in 1880, particularly for those who were involved in anti-colonial uprisings and political prisoners. The prison was never used for large numbers of people, and no significant uprisings or revolts occurred there, though it is said that the conditions were harsh. Before the prison was established, the island played a part in the transatlantic slave trade. Zanzibar was a major hub for the slave trade during the 19th century, and Changuu Island was used as a holding facility for slaves awaiting shipment to markets in the Middle East or the Indian Ocean islands. After the abolition of the slave trade in Zanzibar in the late 19th century, the island’s role shifted.

In the 20th century, Changuu Island was further transformed. It became a tourist attraction, and in the early 1900s, a group of giant Aldabra tortoises was brought to the island, which has now become one of the island’s main attractions. The tortoises are descendants of animals that were initially brought to Zanzibar from Seychelles.
