A site in southeast Nigeria dating to the 9th century AD with rich Iron Age deposits and bronze objects. It has yielded remarkable evidence for artistic and technological development and accumulation of wealth in that part of West Africa during the closing centuries of the 1st millennium AD. A corpse was interred in a deep pit, sitting on a stool surrounded by extensive regalia; the burial chamber was then roofed over and the bodies of attendants were placed above it. Further offerings were deposited nearby, most notably the delicate and intricate cire perdue bronze castings of vases, bowls, and items of personal adornment. Domestic pottery and enormous numbers of glass beads were also in the deposits.
