The architecture of Africa, like other aspects of the culture of Africa, is exceptionally diverse. Throughout the history of Africa, Africans have had their own architectural traditions. In some cases, broader styles can be identified, such as the Sahelian architecture of an area of West Africa. One common theme in much traditional African architecture is the use of fractal scaling: small parts of the structure tend to look similar to larger parts, such as a circular village made of circular houses.
As with most architectural traditions elsewhere, African architecture has been subject to numerous external influences from the earliest periods for which evidence is available. Western architecture has also influenced coastal areas since the late 15th century, and is now an important source for many larger buildings, particularly in major cities.
African architecture uses a wide range of materials. One finds structures in thatch, stick/wood, mud, mudbrick, rammed earth, and stone, with the preference for materials varying by region: North Africa for stone and rammed earth, Horn of Africa for drystone and mortar, West Africa for mud/adobe, Central Africa for thatch/wood and more perishable materials, Southeast and Southern Africa for stone and thatch/wood.
Probably the most famous class of structures in all Africa, the pyramids of Egypt remain one of the world's greatest early architectural achievements, if limited in practical scope and originating from a purely funerary context. Egyptian architectural traditions also saw the rise of vast temple complexes and buildings.
Little is known of ancient architecture south and west of the Sahara. Harder to date are the monoliths around the Cross River, which has geometric or human designs. The vast number of Senegambian stone circles also evidence an emerging architecture.
Egypt's achievements in architecture were varied from temples, enclosed cities, canals, and dams.
