Ruins of Koumbi Saleh, Mauritania

Koumbi Saleh, or Kumbi Saleh, is the site of a ruined ancient and medieval city in south east Mauritania that may have been the capital of the Ghana Empire.

The discovery in 1913 of a 17th-century African chronicle that gave the name of the capital [of Ghana] as Koumbi led French archaeologists to the ruins at Koumbi Saleh. Excavations at the site have revealed the ruins of a large Muslim town with houses built of stone and a congregational mosque but no inscription to unambiguously identify the site as that of capital of Ghana.

In recent years, the identification of Koumbi Saleh with the 'city of Ghana' described in the sources has been increasingly disputed by scholars.
