BRAZIL

BRAZIL: Digs being conducted on Rio de Janeiro's waterfront in advance of the 2016 Olympics have revealed the remains of Valongo Wharf, where as many as a million African slaves were unloaded and traded in the early 19th century. Once considered a shameful blot on the city's history, the site will now be preserved. It has produced artifacts of both Rio's ruling classes and slaves, including cowrie shells and amulets representative of African spiritual practices.
