A little bit of history on Prison Island 

Also known under the Swahili name of "Changuu", this island of 800 meters long by 230 meters wide owes its name "Prison Island" to the fact that it served as a prison for rebel slaves in the 1860 years, then for the prisoners from Tanzania.

Subsequently, the island became a quarantine island where we took them, especially people with yellow fever.

Subsequently, in 1919 the governor english Seychelles a Free to Changuu Island 4 giant tortoises. Gradually, the number of giant tortoises increased enormously and people began to steal these tortoises to sell them. 

The government of Zanzibar has since implemented a protection program for the giant tortoises of Prison Island. Today, there are more than 200 turtles there. Among them, the oldest in the world is 200 years old.
