Djenné: Settlements and Markets in West Africa
Settlements in the inland Niger Delta grew into trading centres, with building traditions adapted to seasonal floods.

The story
The Djenné heritage area preserves settlements and urban remains from different periods. UNESCO traces occupation to about 250 BCE. Later markets became links in trans-Saharan gold trading, and the town was a centre of Islamic learning and dissemination in the fifteenth and sixteenth centuries. Houses built on raised ground responded to seasonal flooding. The early archaeological settlements and the later town should not be treated as one city founded in a single year, nor are all surviving buildings ancient.
Elsewhere in the world
Early occupation at Djenné broadly overlapped with Meroë in the upper Nile valley; the history of African inland settlements long predates Atlantic commerce.
