A military bunker located within Mapungubwe National Park, near the former South African Defence Force camp at Greefswald. This structure was part of South Africa's border defense installations along the frontier with Zimbabwe and Botswana. The bunker was constructed using corrugated iron sheeting, a common material for temporary or semi-permanent military installations.
When the National Parks department took possession of the area, most military installations were demolished, but this bunker was preserved as a historical reminder of the site's military past.
