African Architecture
The architecture of Africa, like other aspects of the culture of Africa, is exceptionally diverse. Many ethno-linguistic groups throughout the history of Africa 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. Westernarchitecture has also had an impact on 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.
Great Zimbabwe is the largest medieval city in sub-Saharan Africa. By the late nineteenth century, most buildings reflected the fashionable European eclecticism and pastisched Mediterranean, or even Northern European, styles.
In the Western Sahel region, Islamic influence was a major contributing factor to architectural development from the later ages of the Kingdom of Ghana. At Kumbi Saleh, locals lived in domed-shaped dwellings in the king's section of the city, surrounded by a great enclosure. Traders lived in stone houses in a section which possessed 12 beautiful mosques, as described by al-bakri, with one centered on Friday prayer. The king is said to have owned several mansions, one of which was sixty-six feet long, forty-two feet wide, contained seven rooms, was two stories high, and had a staircase; with the walls and chambers filled with sculpture and painting.
Sahelian architecture initially grew from the two cities of Djenné and Timbuktu. The Sankore Mosque in Timbuktu, constructed from mud on timber, was similar in style to the Great Mosque of Djenné. The rise of kingdoms in the West African coastal region produced architecture which drew on indigenous traditions, utilizing wood. The famed Benin City, destroyed by the Punitive Expedition, was a large complex of homes in coursed clay, with hipped roofs of shingles or palm leaves. The Palace had a sequence of ceremonial rooms, and was decorated with brass plaques.
Ancient Egyptian architecture
The ancient Egyptians built their pyramids, tombs, temples and palaces out of stone, the most durable of all building materials. Although earthquakes, wars and the forces of nature have taken their toll, the remains of Egypt's monumental architectural achievements are visible across the land, a tribute to the greatness of this civilization. These building projects took a high degree of architectural and engineering skill, and the organization of a large workforce consisting of highly trained craftsmen and labourers.
Apart from the pyramids, Egyptian buildings were decorated with paintings, carved stone images,hieroglyphs and three-dimensional statues. The art tells the story of the pharaohs, the gods, the common people and the natural world of plants, birds and animals. The beauty and grandeur of these sites are beyond compare. How the ancient Egyptians were able to construct these massive structures using

primitive tools is still a mystery.
Maghreban Architecture
Thousands of tombs were left by Berbers that were pre-Christian in origin and whose architecture was unique to north-west Africa. The most famous was Tomb of the Christian Woman in western Algeria. This structure contains column domed and spiraling pathways that lead to a single chamber.

Nubian architecture
Nubian Architecture is one of the most ancient in the world. The earliest style of Nubian Architecture include the speos, structures carved out of solid rock, an A-Group(3700-3250 BCE) achievement. Egyptians made extensive use of the process at Speos Artemidos and Abu Simbel. A-Group eventually led to C-Group. C-Group began with light, supple materials, animal skins, and wattle and daub. Later larger more structures of mudbricks became the norm. C-Group culture was related to Kerma. Kerma was settled around 2400 BC. It was a walled city containing religious building, large circular dwelling, a palace, and well laid out roads. On the East side of the city, funerary temple and chapel were laid out. It supported a population of 2,000. One of its most enduring structures was the Deffufa, a mudbrick temple ceremonies were performed on top. Between 1500-1085 BC, Egyptian conquest and domination of Nubia was achieved.

This conquest brought about the Napatan Phase of Nubian history, the birth of the Kingdom of Kush. Kush was immensely influenced by Egypt and eventually conquered Egypt. During this phase, we see the building of numerous pyramids and temples. Gebel Barkal in the town of Napata was a very significant site. Kushite pharaohs received legitimacy. Thirteen temples have been excavated and two palaces in Napata. Napata has yet to be fully excavated. Nubian pyramids were constructed on three major sites El Kurru, Nuri, and Meroe. Sudan has more pyramids than Egypt. Sudan contains 223pyramids. They were smaller than Egyptian Pyramids. Nubian pyramids were for Kings and Queens. The general construction of Nubian pyramids consisted of steep walls, a chapel facing East, stairway facing East, and a chamber access via the stairway. The Meroe site has the most Nubian pyramids and is considered the largest archaeological site in the world. Around AD 350 the area was invaded by the Ethiopian kingdom of Aksum and the kingdom collapsed.
Aksumite architecture
The best known building of the period in the region is the ruined 8th-century BC multi-storey tower at Yeha in Ethiopia, believed to have been the capital of D'mt.
Aksumite Architecture flourished in the region from the 4th century BC onward, persisting even after the transition of the Aksumite dynasty to the Zagwe in the 12th century, as attested by the numerous Aksumite influences in and around the medieval churches of Lalibela. Stelae (hawilts) and later entire churches were carved out of single blocks of rock, emulated later at Lalibela and throughout Tigray. Other monumental structures include massive underground tombs often located beneath stelae. The stelae is the single largest monolithic structure ever erected (or attempted to be erected). Other well-known structures employing the use of monoliths include tombs such as the "Tomb of the False Door" and the tombs of Kaleb and Gebre Mesqel in Axum.

Most structures, however, like palaces, villas, commoner's houses, and other churches and monasteries, were built of alternating layers of stone and wood. The protruding wooden support beams in these structures have been named "monkey heads" and are a staple of Aksumite architecture and a mark of Aksumite influence in later structures. Some examples of this style had whitewashed exteriors and/or interiors, such as the medieval 12th-century monastery of Yemrehanna Krestos near Lalibela, built during the Zagwe dynasty in Aksumite style. Contemporary houses were one-room stone structures or two-storey square houses or roundhouses of sandstone with basalt foundations. Villas were generally two to four stories tall and built on sprawling rectangular plans (cf. Dungur ruins). A good example of still-standing Aksumite architecture is the monastery of Debre Damo from the 6th century.
