Zanzibar is a Tanzanian archipelago off the coast of East Africa. It is located in the Indian Ocean, and consists of many small islands and two large ones: Unguja (the main island, referred to informally as Zanzibar) and Pemba Island. The capital is Zanzibar City, located on the island of Unguja. Its historic centre, Stone Town, is a World Heritage Site. Zanzibar is also a semi-autonomous region that united with Tanganyika in 1964, and formed the present-day United Republic of Tanzania. The archipelago's main industries are spices, raffia, and tourism.
