Tanzania’s only protected coastal wildlife preserve was gazetted in 1964. It covers an area of some 250 sq km from the Wami River in the south to the Mligaji River in the north, with the Moshi railway line as the western boundary. Saadani is located in what is historically a very important coastal strip emerging as an important trading post, appearing on maps from the early 19th century. The village also contains a ruined fort, built by Arab slavers in the last century. This fort later became a German Boma (administrative centre) after 1888.
