Great Zimbabwe, a world heritage site, is located in Sub-Saharan Africa. By far the most significant of ruins that are spread throughout the region, Great Zimbabwe was at the center of an advanced culture of the late Iron Age.
The site was constructed and continually inhabited from the 11th century to the 15th century by the Shona people. Built in a gold rich region, it became a very powerful center of trade, and likely exported gold and ivory.
The ruins are generally divided into three groups: the Hill Ruins, the Great Enclosure and the Valley Ruins. The Hill Ruins were the center of the city. To the south of them is the Great Enclosure, with walls that reach up to thirty six feet.
