The Senegambian stone circles lie in Gambia north of Janjanbureh and in central Senegal. Coordinates: 13° 41 N - 15° 31 W. Approximate area: 15,000 square miles (39,000 km²). They are sometimes divided into the Wassu (Gambian) and Sine-Saloum (Senegalese) circles, but this is purely a national division.
