The Matobo Hills some 35 km south of Bulawayo are a profusion of distinctive granite landforms, densely packed into a comparatively tight area, that rise up to form a sea of hills. People have interacted with, and been inspired by, the dramatic natural rock formations of the Matobo Hills for over many millennia. The Matobo Hills have one of the highest concentrations of rock art in Southern Africa dating back at least 13,000 years. The rich evidence from archaeology and from the rock paintings at Matobo provides evidence that the Matobo Hills have been occupied over a period of at least 500,000 years. The authenticity of the hunter-gatherer and a few agriculturist rock paintings in the Matobo Hills area has been widely confirmed.
