What was discovered

Excavated by Susan and Roderick McIntosh from 1977, this settlement grew from c. 250 BC to some 33 hectares by AD 800, with mud-brick, pottery, iron and river trade. It showed that sub-Saharan urbanism predated and was independent of trans-Saharan trade.

Occupation continued until c. 1400, when the population moved to present-day Djenné; the site is a World Heritage Site.

What it led to

  • the concept of 'dispersed' or heterarchical urbanism
  • a rewriting of the origin of Sahelian cities
  • the basis of the Djenné mud-brick tradition
