Senegambian stone circles
Archaeological site in Senegal and the Gambia
Also called the Wassu stone circles, groups of megalithic stone circles in central Senegal and in the Gambia north of Janjanbureh, spread over an area of 30,000 km² (12,000 sq mi). They are sometimes split into Sine-Saloum (Senegalese) and Wassu (Gambian) circles, but only along national lines.
