Wonderwerk Cave is a large dolomite cave in the Kuruman Hills of South Africa that preserves a near-continuous record of human occupation and environmental change spanning roughly two million years. It contains some of the earliest evidence for stone tool manufacture and for the controlled use of fire in a cave context, as well as later rock art and artifacts spanning to the historic period.

Location & geology
Location & geology
The cave formed as a phreatic solution cavity in ancient dolomite and extends about 140 m into the hillside. The host rock is extremely old (Precambrian dolomite), which provided a stable shelter that collected windblown sands, ash and organic deposits over millions of years.

Early stone tools
Excavations have recovered flaked stone pieces consistent with the Oldowan tradition in the lowest archaeological layers. These represent some of the earliest known stone-tool manufacture found inside a cave context in southern Africa.

Evidence for early controlled fire
Microscopic and macroscopic analyses show ash layers, charcoal, heated bone and thermally altered stones in place — interpreted as hearths used by hominins about a million years ago. This evidence is central to debates about when and how our ancestors learned to make and use fire.

Rock art and Later Stone Age artefacts
Within ~40 m of the entrance there are San rock paintings and engraved pieces from the Later Stone Age. Ostrich-eggshell beads and engraved small stones show decorative and symbolic behaviours in the more recent layers.

Paleoenvironmental record
Owl-roost deposits, rodent bones, pollen, phytoliths and other microfossils preserved in the sediments allow reconstruction of vegetation and climate change in the surrounding Kalahari region over long timescales.

Preservation & Ethics
Preservation & Ethics
Wonderwerk Cave is recognized as a Grade I National Heritage Site, placing it among South Africa’s most important cultural and scientific landmarks. The cave is under the stewardship of the McGregor Museum in Kimberley, and the Smit family, which oversees research, conservation, and public education. Ongoing preservation efforts focus not only on protecting the fragile sediments and rock art within the cave but also on ensuring respectful collaboration with local communities and descendant groups, who hold cultural and historical connections to the site.
In the past, parts of the cave were damaged when farmers dug for guano (fertilizer) in the 1940s, disturbing some archaeological layers. Today, however, modern archaeology uses non-invasive techniques and strict ethical guidelines to prevent further loss, ensuring that excavation and sampling are done with minimal impact. This balance of conservation, scientific research, and cultural respect safeguards Wonderwerk’s record for both present and future generations.
