Dakar Region is the smallest and most populated Region of Senegal, encompassing the capital city of the country, Dakar, and all its suburbs along the Cap–Vert Peninsula, Africa's most westerly point.
Senegal is subdivided into 14 regions, each of which is administered by a Conseil Régional elected by population weight at the arrondissement level. Senegal is further subdivided into 45 departments, 103 arrondissements and by collectivités locales which elect administrative officers. Three of these regions were created on 10 September 2008, when Kaffrine Region was split from Kaolack, Kédougou region was split from Tambacounda, and Sédhiou region was split from Kolda.
The Senegambian stone circles or the Wassu stone circles are groups of megalithic stone circles that lie in The Gambia north of Janjanbureh and in central Senegal. Spread across a region 30,000 km2 (12,000 sq mi), they are sometimes divided into the Wassu (Gambian) and Sine-Saloum (Senegalese) circles, but this is purely a national division. Containing over 1000 stone circles and tumuli spread across an area 350 km (220 mi) long and 100 km (62 mi) wide, the Senegambian stone circles are the largest concentration of stone circles seen anywhere in the world and an extensive sacred landscape that was used for more than 1500 years. As a result, the sites were inscribed on the UNESCO World Heritage List in 2006.
The 14 regions of Senegal are subdivided into 46 departments and 103 arrondissements and by collectivités locales which elect administrative officers.
