During the early 1930s an African cemetery was discovered fortuitously at Arroyo de Leyes, a free settlement of Arroyo de Leyes, 550km from Buenos Aires, Argentina. Hundreds of bodies were buried here with pottery from the late 17th to early 19th centuries. But since the discoveries could not be related to the native archaeological culture of the area, most of them were destroyed or neglected by museums and archaeologists and for the next fifty years the name of the place and its objects remained forbidden topic in academic circles until the find’s importance was reconsidered recently. However by this time, the site and objects had almost vanished which included the people who lived at or near the site.
