Île de Gorée
Île de Gorée or Gorée Island is one of the 19 communes d'arrondissement (i.e. districts) of the city of Dakar, Senegal. Gorée is a small island 900 meters in length and 350 meters in width sheltered by the Cape Vert Peninsula located 2 kilometers (1.1 nautical miles or 1.2 miles) at sea from the main harbor of Dakar.
Gorée is famous as a destination for people interested in the Atlantic slave trade but relatively few slaves were processed or transported from there. Gorée is known as the location of the House of Slaves (French: Maison des esclaves), built by an Afro-French Métis family about 1780–1784. The House of Slaves is now used as a tourist destination to show the horrors of the slave trade throughout the Atlantic world.
