The Island of Gorée lies off the coast of Senegal, opposite Dakar. From the 15th to the 19th century, it was the largest slave-trading centre on the African coast. Ruled in succession by the Portuguese, Dutch, English and French, its architecture is characterized by the contrast between the grim slave-quarters and the elegant houses of the slave traders. Today it continues to serve as a reminder of human exploitation and as a sanctuary for reconciliation.
Uhm uhm...not even sure if this qualifies as an Unesco card as it doesn't show any infrastructure; but i'll be cheeky with this one heh xD
