Once thought (erroneously) to be a city of the biblical Queen of Sheba, Great Zimbabwe stands as the most important archaeological site yet found in sub-Saharan Africa. Though historians are still seeking answers about the origin and purpose of the city, evidence suggests the Shona, ancestors of the modern Bantu, built it beginning around A.D. 1250 and that it served as a spiritual center.
