The Stone Town of Zanzibar is a fine example of the Swahili coastal trading towns of East Africa. It retains its urban fabric and townscape virtually intact and contains many fine buildings that reflect its particular culture, which has brought together and homogenized disparate elements of the cultures of Africa, the Arab region, India, and Europe over more than a millennium.

Located on a promontory jutting out from the western side of Unguja island into the Indian Ocean, the Stone Town of Zanzibar is an outstanding example of a Swahili trading town. This type of town developed on the coast of East Africa, further expanded under Arab, Indian, and European influences, but retained its indigenous elements, to form an urban cultural unit unique to this region.

The buildings of the Stone Town, executed principally in coralline ragstone and mangrove timber, set in a thick lime mortar and then plastered and lime-washed, reflect a complex fusion of Swahili, Indian, Arab and European influences in building traditions and town planning. The two storey houses with long narrow rooms disposed round an open courtyard, reached through a narrow corridor, are distinguished externally by elaborately carved double 'Zanzibar' doors, and some by wide vernadahs, and by richly decorated interiors.
