The Zanzibar Archipelago is a tropical paradise off the coast of Tanzania in the Indian Ocean. Golden beaches, cerulean waters, and swaying palm trees make for an amazingly beautiful place. There are four main islands, Unguja, Pemba, Mafia and the uninhabited Latham Islands, along with many smaller islands that surround them. You’ll find Zanzibar City, famous for its historic Stone Town area and its connection to the spice and slave trades in the 19th century, on Unguja Island.
Wikipedia says The Zanzibar Archipelago (Arabic: أرخبيل زنجبار, Swahili: Funguvisiwa la Zanzibar) consists of several islands lying off the coast of East Africa south of the Somali sea. The archipelago is also known as the Spice Islands. There are four main islands, three primary islands with human populations, a fourth coral island that serves as an essential breeding ground for seabirds, plus a number of smaller islets that surround them and an isolated tiny islet.
Most of the archipelago belongs to the Zanzibar semi-autonomous region of Tanzania, while Mafia Island and its associated islets are part of the Pwani Region on the mainland.
Stone Town of Zanzibar (Arabic: مدينة زنجبار الحجرية), also known as Mji Mkongwe (Swahili for "old town"), is the old part of Zanzibar City, the main city of Zanzibar, in Tanzania. The newer portion of the city is known as Ng'ambo, Swahili for 'the other side'. Stone Town is located on the western coast of Unguja, the main island of the Zanzibar Archipelago. Former capital of the Zanzibar Sultanate, and flourishing centre of the spice trade as well as the slave trade in the 19th century, it retained its importance as the main city of Zanzibar during the period of the British protectorate. When Tanganyika and Zanzibar joined each other to form the United Republic of Tanzania, Zanzibar kept a semi-autonomous status, with Stone Town as its local government seat.
Stone Town is a city of prominent historical and artistic importance in East Africa. Its architecture, mostly dating back to the 19th century, reflects the diverse influences underlying the Swahili culture, giving a unique mixture of Arab, Persian, Indian and European elements. For this reason, the town was designated as a UNESCO World Heritage Site in 2000.
