Deux Mamelles, Collines des Mamelles, or simply Mamelles are twin hills located in Ouakam, a suburban commune of Dakar, in the Cap-Vert peninsula, Senegal.
These hills are of volcanic origin[1] and they are the vestiges of a plateau from the early Quaternary.[2] The highest hill is only 105m (344feet) high, but they stand out in the landscape owing to the flat surroundings. The name of these breast-shaped hills comes from the French term “Mamelle”, a name commonly applied in the French-speaking parts of the world to a breast.[3]
On the seaward hill stands a lighthouse, the Phare des Mamelles, while on the hill further ashore the African Renaissance Monument was erected and unveiled in 2010.
