The subsequent sultans established their capital and seat of government at Zanzibar Town where a palace complex was built on the sea front. By 1896, this consisted of the palace itself; the Beit al-Hukm, an attached harem; and the Beit al-Ajaib or "House of Wonders"—a ceremonial palace said to be the first building in East Africa to be provided with electricity. The complex was mostly constructed of local timber and was not designed as a defensive structure. All three main buildings were adjacent to one another in a line, and linked by wooden covered bridges above street height.
