The Great Mosque of Djenné is the largest mud brick building in the world and is considered by many architects to be the greatest achievement of the Sudano-Sahelian architectural style, albeit with definite Islamic influences.

It is located in the city of Djenné, Mali on the flood plain of the Bani River. The first mosque on the site was built in 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.
