The Ancient Guardians of Prison Island: The Giant Tortoises of Zanzibar
One of the most fascinating things about Prison Island in Zanzibar is the presence of giant Aldabra tortoises — majestic, slow-moving creatures that have become iconic symbols of the island. These tortoises were gifted to Zanzibar in the late 19th century from the Aldabra Atoll in Seychelles.
Some of these tortoises are over 150 years old, making them living monuments of time. They can grow to over 200 kg in weight and live longer than many human lifetimes. Today, they live peacefully on Prison Island in a protected sanctuary, where visitors from around the world come to see, feed, and learn about them.
Sadly, the population once declined due to theft and poor care, but thanks to conservation efforts by the government and environmental groups, the tortoises are now thriving again.
Their presence adds not only beauty to the island but also teaches us about patience, conservation, and the value of history. If you ever visit Zanzibar, don't miss the chance to meet these gentle giants.
