The recently rediscovered Quay of Valongo, the arrival point for half a million slaves into Rio de Janeiro, is being considered for inclusion on UNESCO's World Heritage List.
The city's black community want to ensure that descendants of slaves and their African heritage will be celebrated and not lost as the area becomes more of a tourist attraction.
