This work describes the traditional architectures of the western half of Nigeria, covering the huge area from the Hausa people of the north to the Yoruba people of the south. The book shows how two main types of architecture have evolved in these areas: in the forest, the distinctive style of the Yoruba and Bini peoples, and in the Savanna the thin-shelled buildings in moulded mud in a variety of attractive forms. It also describes later developments, including the Hausa town style with its massive mud walls supporting flat or domed roofs. The book describes and evaluates the traditional artistry, design, craftsmanship and building methods employed in mosques, churches, palaces and domestic architectures, and shows the dramatic impact of modernization on traditional building.
