Prison Island
Prison Island, also known as Changuu Island, is one of the most popular historical and natural attractions in Zanzibar. Located about 5.6 kilometers northwest of Stone Town on Unguja Island, the island offers visitors a unique blend of history, wildlife, and beautiful tropical scenery. With its turquoise waters, coral reefs, and famous giant tortoises, Prison Island has become a must-visit destination for travelers exploring Zanzibar.
Despite its name, the island was never heavily used as a prison. Instead, it later became an important quarantine station during the colonial period. Today, the island attracts visitors who want to learn about Zanzibar’s history while enjoying its peaceful natural environment.
Historical Background
The history of Prison Island dates back to the late nineteenth century during the rule of the Sultan of Zanzibar. The island was originally owned by Arab traders and later purchased by the Sultan. In the 1890s, British colonial authorities planned to build a prison on the island to house rebellious slaves and criminals. The prison complex was constructed, but it was never actually used for its original purpose.
Instead, the buildings were later used as a quarantine station for travelers arriving in Zanzibar. During that time, ships arriving from different parts of the world were required to stop at the island so passengers could be checked for contagious diseases. People suspected of carrying illnesses such as yellow fever or cholera were temporarily isolated on the island before being allowed to enter Zanzibar.
Today, the old prison and quarantine buildings still stand on the island and have become important historical landmarks. Visitors can walk through these structures and learn about the island’s fascinating colonial history.
Giant Aldabra Tortoises
One of the most famous attractions on Prison Island is the population of giant Aldabra tortoises. These tortoises were originally brought to the island in the late nineteenth century as a gift from the Seychelles. Over time, the tortoises became one of the island’s most important wildlife attractions.
The giant Aldabra tortoise is one of the largest tortoise species in the world, with some individuals weighing more than 200 kilograms. These gentle animals can live for over one hundred years, making them a remarkable symbol of longevity and conservation.
Visitors to the island can observe these tortoises in a protected sanctuary and learn about their history and conservation efforts. Many visitors enjoy feeding the tortoises and taking photographs while learning about how the population has been carefully protected for many years.
Beaches and Marine Life
Prison Island is surrounded by beautiful beaches and clear blue waters, making it an excellent place for relaxation and marine activities. The island’s coral reefs are home to a wide variety of tropical fish and marine life, making snorkeling a popular activity for visitors.
The calm and shallow waters around the island are ideal for swimming and exploring the underwater environment. Visitors often enjoy snorkeling along the coral reefs where they can see colorful fish, coral formations, and occasionally sea turtles.
The island’s natural beauty, combined with its peaceful atmosphere, makes it a perfect destination for travelers who want to enjoy a quiet escape from the busy streets of Stone Town.
