Prison Island was uninhabited until the 1860s, when the first Sultan of Zanzibar gave it to two Arab slave traders, who transformed it into a place of detention for unruly slaves.
At the start of the twentieth century, following yellow fever outbreaks across British East African colonies, the island served as a quarantine station for Zanzibar, Kenya, Uganda and Tanganyika — the former prison converted into a hospital. Today it is known as Turtle Island, home to the giant Seychelles tortoises.
