Limestone grottoes at Witdraai in the Kgalagadi Transfrontier Park. These grottoes played an important part in the ǂKhomani San's cultural heritage. At one time, they were used as a prison for the San and inmates were chained to the interior walls. In later times, upon returning from the Empire Exhibition, the participants discovered their homes had been burnt down by Basters (the descendants of Cape Colony Dutch and indigenous African women). Several San community members including Ouma |Una Rooi came to live here.Images from this trip document the first excursions into the Kgalagadi Transfrontier Park and were a central part of the work on oral history and mapping in the first years of research.
