The Great Zimbabwe Walls were constructed from Granite blocks gathered from the exposed rock of the surrounding Hills. 

Here is how the Great Wall was built: no mortar was used:All of the Great Zimbabwe walls were fitted without the use of mortar by laying stones one on top of the other. Each layer slightly more recessed. Each layer was slightly more recessed than the last to produce a stabilizing inward slope. Early examples were coarsely fitted using rough blocks and incorporated features of the landscape such as boulders into the walls. 

Later walls were fitted together closely and evenly over long serpentine courses to produce remarkably finished surfaces.

In Southern Africa, there are at least 600 stone built ruins in the regions of Zimbabwe, Mozambique and South Africa. These ruins are called Madzimbabwe in chiKaranga the Bantu language of the builders. In the past, fierce controversy raged concerning the identity of Mapungubwe's occupants, and, as in the case of Great Zimbabwe, early excavators refused to accept that it could have been built by Africans. 

Mapungubwe's skeletal and cultural remains are, how ever, identical to those found at other Iron Age settlements in the African continent, which have proven that these civilisation were built by Africans.
