Context

The settlement that we see today was a development of the architectural form that emerged at Great Zimbabwe in the 13th century AD and a local Leopard's Kopje culture that built platforms of rough walling on which houses would be constructed. Khami marks an innovation that recognised the environment in which was built. The area around Khami, being riverine, is hot and had problems with malaria. The stone found at Khami (laminar granite) was different from the ones found in other areas of Zimbabwe (biotite). With a mixture of dolerite, this stone was harder to quarry and produced shapeless building stone. It can be estimated that over 60% of the stone produced at these quarries would not be of building quality. The building blocks thus needed to be shaped, but even then the stones were not suitable for building free-standing dry stone walls. The builders thus made an innovation and produced retaining walls instead. Secondly, building platforms made the houses cooler than those in the open areas below. It also eliminated the problem of malaria for the lucky royals who stayed in the built-up areas. The walls are gravity retaining walls built without mortar. Unlike at Great Zimbabwe, some of the walls at Khami have foundations built with huge blocks which would have been lifted by at least four people. Excavations have revealed well-planned buildings especially at the Hill Complex, which was occupied by the king. The complex was first built up by creating terraces of rough walling. These stable walls were then covered up by quality walling of dressed stone blocks. Each terrace was highly decorated with either a checkerboard pattern, herringbone, or a cord pattern. The terraces leaned inwards so that gravity would not cause collapses. The terraces that were created by leaning inwards had wooden poles probably for the guards to hold on to as they walked along the high and steep walls.
