One of the most interesting places in Zanzibar is the island of Chang or the island of Prison (Prison - prison). This name was not accidental. Many years ago, a British general built a prison on this island, but it was never used for its intended purpose. Before the arrival of the British, Zanzibar was ruled by the Arabs. The Arab slave owners used the island to keep their slaves until they could find further buyers for them. So the name Prison stuck to the island.
Nowadays, the island is famous for its snow-white beaches, rich underwater world, as well as giant tortoises living here. There are individuals of turtles that have reached the age of more than 100 years.
In 1919, the governor of the Seychelles presented several huge Aldabra tortoises. The animals multiplied rapidly, and already in 1955 there were 200 of them. However, the locals used turtles for food and for sale, therefore, by the 90s of the last century, there were about 20 Aldabra.
