The Senegambian stone circles are a collection of over 1,000 megalithic stone circles and related structures found in the Gambia and Senegal. These ancient structures are believed to date back to between the 3rd century BC and the 16th century AD, and are thought to have been used for religious or ceremonial purposes.

The stone circles are made up of large stones, some weighing up to several tons, arranged in circular or semi-circular patterns. Many of the stones have carvings or engravings on them, which are thought to represent the different social groups that used the sites.

The Senegambian stone circles are believed to have been created by the people of the Soninke culture, who lived in the area from around the 3rd century BC until the 11th century AD. The circles are also thought to have been used by other cultures that lived in the area, such as the Serer and Jola.

The Senegambian stone circles were designated a UNESCO World Heritage site in 2006. They are considered an important cultural and historical site, and attract many visitors each year. The sites are also important for scientific research, as they provide insight into the ancient cultures and social structures of the people who created them.
