Iron was discovered through particular stones which become hot and cool and finally change to a hard matter known as iron. In East Africa, the iron age is believed to have begun around 1000AD. Famous early iron sites were discovered in Engaruka within the rift valley in Northern Tanzania. Other sites include Uvinza, Karagwe, Ugweno, Iteso and western shores of lake Victoria.
