The Great Mosque of Djenné is the largest mud brick building in the world.
The mosque is located in the city of Djenné in Mali on the flood plain of the Bani River.
In April 1893 the French colonel Archinard took [a picture of] Djenne (now Mali) and found the old mosque in a pitiable state.
It is one of the most famous landmarks in Africa. Along with the ‘Old Towns of Djenné’ it was dubbed a World Heritage Site by UNESCO in 1988.
The 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 Great Mosque was constructed on a raised platform with a surface area of 5625 m² (62,500 ft²), which has so far protected the mosque from even the most severe floods.
