Phare des Mamelles

Built in 1864 on the higher of the two hills of the Mamelles, at an elevation of 126 meters, the Lighthouse of the same name is considered the most powerful Lighthouse in Africa, along with the one of Cap de Bonne-Esperance. It is also one of the oldest symbols of Senegal’s national heritage.

At the top, a historic building of 16 meters height host «the great lamp», a Fresnel lens rotating on a vessel of Mercury at the speed of 5 seconds per rotation. This lens acts as an amplifier and gives it a range of 53 km. More than 150 years ago, this luminous code told the boats that they were approaching Dakar by illuminating the dark with white glow every 5 seconds.
