Stone Town is the historic centre of Zanzibar City, a UNESCO World Heritage Site of narrow streets, carved wooden doors, coral-stone buildings, and mosques built over a thousand years of Indian Ocean trade. It was the commercial capital of the Omani Sultanate in the 19th century and, for a period, the largest city in East Africa. Most visitors use it as a 1 to 2 night base before or after the northern beach resorts, but the old town repays slower exploration.

Prison Island – A Day Trip from Stone Town

Located just a short boat ride from Stone Town, Prison Island (also known as Changuu Island) is one of Zanzibar’s most fascinating destinations. Renowned for its rich history, ecological significance, and picturesque surroundings, Prison Island offers visitors a unique blend of cultural heritage and natural beauty. This article explores the island’s historical background, ecological importance, and modern-day attractions.

Historical Background

Despite its name, Prison Island was never used as a formal prison, though its original purpose was connected to the island’s role in the region’s colonial and economic history.

Ecological Significance

Prison Island is home to a unique and important ecosystem that attracts nature lovers and conservationists alike:
