[[Image:Great Mosque of Djenné 1.jpg|thumb|230px|The [[Great Mosque of Djenné]] in [[Mali]], the largest mud-brick building in [[sub-Saharan Africa]]<ref name=":242322" />]]'''Sudano-Sahelian architecture''' refers to a range of similar indigenous [[architectural style]]s common to the [[Ethnic groups of Africa|African people]]s of the [[Sahel]] and [[Sudan (region)|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 [[mudbrick]]s and [[adobe]] plaster, with large wooden-log support [[Beam (structure)|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.

== Historical background ==
Large [[Neolithic]] proto-urban walled stone settlements, likely built by Mande-speaking Soninke peoples date from around 1,600-400 BC at [[Dhar Tichitt]] and nearby sites in southeastern [[Mauritania]].<ref>{{Cite journal |last=Holl |first=Augustin F.C. |date=2009 |title=Coping with uncertainty: Neolithic life in the Dhar Tichitt-Walata, Mauritania, (ca. 4000–2300 BP) |url=https://www.researchgate.net/publication/248548075 |journal=C.

This is the present congregational mosque. He built another palace for himself and his household near the mosque on the east side." {{Harvnb|Hunwick|1999|p=18}}</ref> 

Starting in the 9th century AD, Muslim merchants came to play a vital role in the western [[Sahel]] region through [[trans-Saharan trade]] networks.<ref name=":2423">{{harvnb|Bloom|Blair|2009|loc=''Africa''}}</ref> The earliest mosques discovered in [[sub-Saharan Africa]] are at [[Kumbi Saleh]] (in present-day southern Mauritania), the former capital of the [[Ghana Empire]].<ref name=":24233">{{harvnb|Bloom|Blair|2009|loc=''Africa''}}</ref> Here, a mosque has been discovered which consisted of a courtyard, a prayer hall, and a square [[minaret]], built in dry stone covered in red mud used as plaster. On both the exterior and interior of the mosque, this plaster was painted with floral, geometric, and epigraphic motifs. A similar stone mosque from the same period has been found at [[Awdaghust]].{{Sfn|Pradines|2022|p=|pp=51–52}} Both mosques are dated generally between the 9th and 14th centuries. The mosque of Kumbi Saleh appears to have gone through multiple construction phases from the 10th century to the early 14th century.{{Sfn|Pradines|2022|p=|pp=51–52}} 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 mosques (as described by [[Al-Bakri]]), one centered on [[Friday prayer]].<ref>Historical Society of Ghana.

A variety of possible influences on this architecture have been suggested. North African and Andalusi architecture to the north may have been one of these,{{Sfn|Petersen|1996|p=306}} with the existence of square minarets possibly reflecting the influence of the [[Great Mosque of Kairouan]].<ref name=":2423" />  As Islamization progressed across the region, more variations developed in mosque architecture, including the adoption of traditional local forms not previously associated with Islamic architecture.<ref name=":24232">{{harvnb|Bloom|Blair|2009|loc=''Africa''}}</ref> Under Songhai influence, minarets took on a more pyramidal appearance and became stepped or tiered on three levels, as exemplified by the tower of the [[Tomb of Askia|mosque–tomb]] of [[Askia Muhammad I|Askia al-Hajj Muhammad]] in [[Gao]] (present-day Mali). In [[Timbuktu]], the [[Sankore Madrasah|Sankoré Mosque]] (established in the 14th-15th centuries{{Sfn|Pradines|2022|p=63}} and rebuilt in the 16th century, with later additions<ref name=":242332">{{harvnb|Bloom|Blair|2009|loc=''Timbuktu''}}</ref>), had a tapering minaret and a prayer hall with rows of arches.<ref name=":24232" /> The presence of tapering minarets may also reflect cultural contacts with M'zab region to the north,<ref name=":24232" /> while decoration found at Timbuktu may reflect contacts with Berber communities in what is now Mauritania.{{Sfn|Petersen|1996|p=307}} More local or indigenous pagan cultures may have also been an influence in the later Islamic architecture of the region.{{Sfn|Petersen|1996|p=306}}

During the French colonial occupation of the Sahel, French engineers and architects had a role in popularizing a "Neo-Sudanese" style based on local traditional architecture but emphasizing symmetry and monumentality.{{Sfn|Petersen|1996|p=308}}<ref name=":24234">{{harvnb|Bloom|Blair|2009|loc=''Africa''}}</ref><ref name=":242322">{{harvnb|Bloom|Blair|2009|loc=''Mali, Republic of''}}</ref> The Great Mosque of Djenné, which was previously established in the 14th century but demolished in the early 19th century,<ref name=":24234" /> was rebuilt in 1906–1907 under the direction of Ismaila Traoré and with guidance from French engineers.<ref name=":242322" />{{Sfn|Petersen|1996|p=308}} Now the largest earthen (mud) building in sub-Saharan Africa, it served as a model for the new style and for other mosques in the region, including the [[Grand Mosque of Mopti]] built by the French administration in 1935.<ref name=":242322" />{{Sfn|Petersen|1996|p=308}} Other 20th-century and more recent mosques in West Africa have tended to replicate a more generic style similar to that of modern Egypt.<ref name=":24234" />

While the architecture of this region shares a certain style, a wide variety of materials and local styles are evident across this wide geographic range.<ref name=":2423" />{{Sfn|Petersen|1996|pp=306–308}} In the more arid western Sahara and northern Sahel regions, stone predominates as a building material and is often associated with Berber cultures. In the southern Sahel and [[Savanna|savannah]] regions mudbrick and [[rammed earth]] are the main material and is now associated with the most monumental examples of West African Islamic architecture. In some places, like Timbuktu and [[Oualata]], both building materials are used together, with stone constructions either covered or bound with a mud plaster.{{Sfn|Petersen|1996|pp=306–307}}

In the [[earthen architecture]] of the region, scholar Andrew Petersen distinguishes two general styles: a "western" style that may have its roots in [[Djenné]] (present-day Mali), and an "eastern" style associated with [[Hausa architecture]] that may have its roots in [[Kano (city)|Kano]] (present-day [[Nigeria]]).{{Sfn|Petersen|1996|p=308}} The eastern or Hausa style is generally more plain on the exterior of buildings, but is characterized by diverse interior decoration and the much greater use of wood.{{Sfn|Petersen|1996|p=308}} Mosques often have prayer halls with pillars supporting flat or slightly domed roofs of wood and mud.<ref name=":24232" />{{Sfn|Pradines|2022|p=84}} An exceptional example is the 19th-century Great Mosque of [[Zaria]] (present-day Nigeria), which has [[Parabolic arch|parabolic]] arches and a roof of shallow domes.<ref name=":24232" /><ref>{{Cite web |title=Archnet > Site > Friday Mosque at Zaria |url=https://www.archnet.org/sites/4180 |access-date=2023-01-04 |website=www.archnet.org}}</ref> The western or "Sudan" style is characterized by more elaborate and decorated exterior façades whose compositions emphasize verticality. They have tapering buttresses with cone-shaped summits, mosques have a large tower over the ''[[mihrab]]'', and wooden stakes (''toron'') are often embedded in the walls ''–'' used for scaffolding but possibly also for some symbolic purpose.{{Sfn|Petersen|1996|p=308}}

== Mud architecture building techniques ==
{{More citations needed section|date=January 2023}}
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.<ref>{{Cite web |title=Construction Technology and Architecture {{!}} Encyclopedia.com |url=https://www.encyclopedia.com/history/news-wires-white-papers-and-books/construction-technology-and-architecture |access-date=2023-01-15 |website=www.encyclopedia.com}}</ref>

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.<ref>{{Cite web |last=Team |first=Editorial |date=2021-03-30 |title=Vernacular Architecture: Tradition and Beauty in Regional Styles |url=https://rmjm.com/vernacular-architecture-tradition-and-beauty-in-regional-styles/ |access-date=2023-01-15 |website=RMJM |language=en-GB}}</ref> 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 Djenné and the Kani-Kombole Mosque of Mali.
*'''[[Songhai architecture|Songhai]]''' – of the various [[Songhai people|Songhai]] groups of Niger and Northern Mali. Characterized by the [[Tomb of Askia]] in [[Gao]], [[Djingareyber]] and the Zarmakoy Palace in [[Dosso, Niger|Dosso]]
*'''Fortress''' style<ref>{{Cite journal |last=Kane |first=Ousmane |date=2015-04-01 |title=Making and Remaking Mosques in Senegal. |url=https://journals.openedition.org/etudesafricaines/18050?lang=en |journal=Cahiers d'études africaines |language=fr |issue=217 |doi=10.4000/etudesafricaines.18050 |issn=0008-0055|doi-access=free }}</ref> – predominantly used by the [[Zarma people|Zarma]]-[[Songhai people|Songhai]] peoples of [[Niger]] and [[Mali]], [[Hausa-Fulani]], [[Tuareg]] and [[Arab]] mixed communities in [[Agadez]], and the [[Kanuri people|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.

Examples in the architecture of the [[Yamma Mosque]] and old town of [[Zinder]], The Hausa quarter of [[Agadez]] Niger, the [[Gidan Rumfa]] of [[Kano (city)|Kano]], and various Hausa districts across [[West Africa]].
*'''Volta basin''' – of the [[Gur people|Gur]] and [[Mandé peoples|Mande]]n groups of [[Burkina Faso]], northern [[Ghana]] and northern [[Côte d'Ivoire]]. Often the most conservative of the various substyles. Typically features 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 [[Grand Mosque of Bobo-Dioulasso|Bobo-Dioulasso Grand Mosque]].

=== 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.{{Infobox UNESCO World Heritage Site
