The Great Mosque of Djenné is the largest mud brick or adobe building in the world and is considered by many architects to be the greatest achievement of the Sudano-Sahelian architectural style, with definite Islamic influences. The mosque is located in the city of Djenné, Mali, on the flood plain of the Bani River. The first mosque on the site was built around the 13th century, but the current structure dates from 1907. As well as being the centre of the community of Djenné, it is one of the most famous landmarks in Africa. Along with the "Old Towns of Djenné" it was designated a World Heritage Site by UNESCO in 1988.

Great Mosque of Djenné[/caption]The actual date of construction of the first mosque in Djenné is unknown, but dates as early as 1200 and as late as 1330 have been suggested. The earliest document mentioning the mosque is al-Sadi’s Tarikh al-Sudan which gives the early history, presumably from the oral tradition as it existed in the mid seventeenth century. The tarikh states that a Sultan Kunburu became a Muslim and had his palace pulled down and the site turned into a mosque. He built another palace for himself near the mosque on the east side. His immediate successor built the towers of the mosque while the following Sultan built the surrounding wall.
The entire community of Djenné takes an active role in the mosque's maintenance via a unique annual festival. This includes music and food, but has the primary objective of repairing the damage inflicted on the mosque in the past year (mostly erosion caused by the annual rains and cracks caused by changes in temperature and humidity). In the days leading up to the festival, the plaster is prepared in pits. It requires several days to cure but needs to be periodically stirred, a task usually falling to young boys who play in the mixture, thus stirring up the contents. Men climb onto the mosque's built-in scaffolding and ladders made of palm wood and smear the plaster over the face of the mosque.

Another group of men carries the plaster from the pits to the workmen on the mosque. A race is held at the beginning of the festival to see who will be the first to deliver the plaster to the mosque. Women and girls carry water to the pits before the festival and to the workmen on the mosque during it. Members of Djenné's masons guild direct the work, while elderly members of the community, who have already participated in the festival many times, sit in a place of honor in the market square watching the proceedings.
The original mosque presided over one of the most important Islamic learning centers in Africa during the Middle Ages, with thousands of students coming to study the Qur'an in Djenné's madrassas. The historic areas of Djenné, including the Great Mosque, were designated a World Heritage Site by UNESCO in 1988. While there are many mosques that are older than its current incarnation, the Great Mosque remains the most prominent symbol of both the city of Djenné and the nation of Mali.
On 20 January 2006 the sight of a team of men hacking at the roof of the mosque sparked a riot in the town. The team were inspecting the roof as part of a restoration project financed by the Aga Khan Trust for Culture. The men quickly disappeared to avoid being lynched. In the mosque the mob ripped out the ventilation fans that had been presented by the US Embassy at the time of the Iraq war and then went on a rampage through the town. The crowd ransacked the Cultural Mission, the mayor's home, destroyed the car belonging to the iman's younger brother and damaged three cars belonging to the iman himself. The local police were overwhelmed and had to call in reinforcements from Mopti. One man died during the disturbances.
On Thursday 5 November 2009, the upper section of the southern large tower of the qibla wall collapsed after 75 mm of rain had fallen in a 24 hour period. The Aga Khan Trust for Culture funded the rebuilding of the tower.
