The oldest ironworking anywhere yet found sits in Central Africa

Two sites carry the earliest known evidence of iron smelting on earth. One is Ôboui, in the west of the Central African Republic. The second, Gbatoro, lies about a hundred kilometres away over the border in Cameroon. Radiocarbon puts both at 1800 BCE or earlier. The excavation reports describe careful work on undisturbed ground, with clean layers sealing the deposits above and below. At Ôboui the whole sequence of the craft is present in one workshop: furnace structures, the clay tuyeres that fed air to the fire, pieces of worked iron, slag, stone anvils for hammering, and charcoal in quantity for dating. Four thousand years ago, in the middle of Africa, people were smelting and forging iron. These are not stray dates from a thin dig. They are two sites, both inside the zone the linguistic evidence had already predicted, both fully excavated and both dated. African iron is older than Anatolian iron by at least three centuries.
