The Cap Blanc Lighthouse (also known as the Ras Nouadhibou Lighthouse) is an active lighthouse located on Ras Nouadhibou (French: Cap Blanc) in Mauritania. Constructed in 1910, it is today located only a few feet from Mauritania's border with Western Sahara. In recent years the lighthouse has been incorporated as the rear range light of a pair of leading lights. A modern fiberglass light structure forms the front of the range. The lighthouse serves as a landfall light for the port of Nouadhibou.[1] [2] A few kilometers northeast near Cansado is the Pointe de Cansado lighthouse, built in 1913.
