As the city of New York has grown up, out, and over an increasingly vast area of land during the past few centuries, various sites of human activity and habitation have become one of the many layers that continue to interest urbanologists, sociologists, planners, and anthropologists. One such layer is the African burial ground that was found in lower Manhattan in 1991, and which has been celebrated by a diverse group of individuals ever since. Visitors will want to start by looking at the "Rites of Ancestral Return" section. Here they may elect to view video clips from past celebrations and view an interactive map that highlights the various ways in which the colonial African experience has been relived and commemorated along the Eastern seaboard. The other section on the site is also quite engaging, as it allows visitors to explore the African burial ground through educational features about the artifacts and graves found within the context of the bustling city which had grown up around the site through the ensuing centuries.
