Sudano-Sahelian

Sudano-Sahelian architecture refers to a range of similar indigenous architectural styles common to the African peoples of the Sahel and Sudanian grassland (geographical) regions of West Africa, south of the Sahara, but north of the fertile forest regions of the coast.

This style is characterized by the use of mudbricks and adobe plaster, with large wooden-log support beams that jut out from the wall face for large buildings such as mosques or palaces. These beams also act as scaffolding for reworking, which is done at regular intervals, and involves the local community. The earliest examples of Sudano-Sahelian style probably come from Jenné-Jeno around 250 BC, where the first evidence of permanent mudbrick architecture in the region is found.

Difference between Savannah and Sahelian styles

The earthen architecture in the Sahel zone region is noticeably different from the building style in the neighboring savannah. The "old Sudanese" cultivators of the savannah built their compounds out of several cone-roofed houses. This was primarily an urban building style, associated with centres of trade and wealth, characterised by cubic buildings with terraced roofs comprise the typical style.

They lend a characteristic appearance to the close-built villages and cities. Large buildings such as mosques, representative residential and youth houses stand out in the distance. They are landmarks in a flat landscape that point to a complex society of farmers, craftsmen and merchants with a religious and political upper class.

With the expansion of Sahelian kingdoms south to the rural areas in the savannas (inhabited by culturally or ethnically similar groups to those in the Sahel), the Sudano-Sahelian style was reserved for mosques, palaces, the houses of nobility or townsfolk (as is evident in the Gur-Voltaic style), whereas among commonfolk, there was a mix between either typically distinct Sudano-Sahelian styles for wealthier families, and older African roundhut styles for rural villages and family compounds.

Mud architecture building techniques

The traditional earth building construction technology has a particular name called “banco” in West Africa, meaning a wet-mud process similar with the concept of coil pottery. When banco technology continues to be the criterion for dwellings in the savannah area, an alternative method is to use earthen brick consequently with wet mud. The brick is cast into rectangular shape and dried in the sun.

One symbol of the Sudanese architecture is the man-made, conical earthen pillars. Being combined with the building itself uniquely, they often project horizontally to the outside like engaged pillars. Being so omnipresent in the vernacular buildings, they can be found singularly or clustered at multiple entrances. As a hallmark of the Sudano Sahelian architecture, they mark the indication of continuity and productivity.

Substyles

The Sudano-Sahelian architectural style itself can be broken down into four smaller sub-styles that are typical of different ethnic groups in the region. The examples used here illustrate the construction of mosques as well as palaces, as the architectural style is concentrated around inland Muslim populations.
As with the people, many of these styles cross-pollinate and produce buildings with shared features. Any one of these styles is not exclusive to one particular modern countries borders, but are linked to the ethnicity of its builders or surrounding populations. For example, a Malian migrant community in traditionally Gur area may build in the style characteristic of their ancestral homeland, while neighbouring Gur buildings are built in the local style. These styles include:

*Malian – of the various Manden groups of southern and central Mali. Characterized by the Great Mosque of Djenne and the Kani-Kombole Mosque of Mali.
*Fortress style – predominantly used by the Zarma- Songhai peoples of Niger, Hausa-Fulani, Tuareg and Arab mixed communities in Agadez, and the Kanuri people of Lake Chad. Military aspect to construction of high protective compound walls built around a central courtyard. Minaret is the only structure with support beams showing. Characterized by the Sankore Mosque of Timbuktu, the tomb of Askia in Gao Mali, and the Agadez mosque of northern Niger.
* Tubali – The characteristic Hausa architectural style predominant in North and Northwestern Nigeria, Niger, Eastern Burkina Faso, Northern Benin, and Hausa-predominant ''zango'' districts and neighbourhoods throughout West Africa. Characterised by its attention of stucco detail in abstract design and extensive use of parapets. One to two storey buildings. Examples in the architecture of the Yamma Mosque and old town of Zinder, The Hausa quarter of Agadez Niger, the Gidan Rumfa of Kano, and various Hausa districts across West Africa.
*Volta basin – of the Gur and Manden groups of Burkina Faso, northern Ghana and northern Cote d'Ivoire. The most conservative of the three styles. A single courtyard, characterized by high white and black painted walls, inward curved turrets supporting an exterior wall, and a larger turret nearer the center. Characterized by the Larabanga mosque of Ghana and the Bobo-Dioulasso Grand Mosque.

Conservation

Several outstanding examples of religious and secular Sudano-Sahelian architecture have been awarded UNESCO World Heritage Site status. The historic centers of Djenné, Mali and Agadez, Niger were inscribed on the World Heritage List in 1988 and 2013, respectively. In 2021, 8 small mosques in northern Côte d’Ivoire exemplifying a special type of Volta Basin religious architecture were also inscribed on the World Heritage list. These mosques were probably originally constructed between the 17th and 19th centuries, as trade routes from the Empire of Mali spread to the south.
