TANGA (“the sail”), a seaport of German East Africa, lying opposite the island of Pemba in 5º 6' S., 39º 7' E. The town is regularly laid out on elevated ground on the southern shore of Tanga Bay, and has a population of about 6000. Among the public buildings are the administrator's residence, the hospital, the boma (barracks), Protestant and Catholic churches and the government and mission schools. Tanga is the port of the Usambara district, where are many thriving plantations. The harbour is entered by a broad channel five to eight fathoms deep. It is a port of call for the German mail steamers, and the starting-point of a railway to the Usambara highlands.
