This extremely detailed city plan of Dakar was published by the Institut Géographique National of France, in 1983, with the assistance of its bureau in Senegal.
Two separate insets show the Cap Vert; and the Île de Gorée, infamous for its association with the slave trade. The island is now a UNESCO World Heritage Site.
Many other maps of Dakar and Senegal are available from TROPICARTA (requires Chomikuj account).
