Cave 36m W of Three Chimneys is a prehistoric cave in Wales, formed in Dinantian limestone bedrock of Mississippian age. The surrounding geology consists of undifferentiated Dinantian rocks comprising limestone with subordinate sandstone and argillaceous deposits, typical of karst terrain where natural cavities develop through the dissolution of soluble limestone by acidic groundwater over geological timescales. The cave's position in this limestone landscape would have made it a valuable refuge for Mesolithic and Neolithic populations, who left evidence of occupation in cave sites throughout Wales during periods when the climate and environment supported human settlement.
The site is protected as a scheduled monument by Cadw, the Welsh heritage body, reflecting its archaeological significance as a potential repository of prehistoric deposits and artefacts. Such caves frequently contain stratified cultural layers, faunal remains and stone tools that illuminate the lifeways of early Welsh communities. The specific location near Three Chimneys places the cave within a broader archaeological context of human activity in the Welsh uplands, where numerous caves and rock shelters document long-term patterns of settlement and resource use. Protection ensures the cave's archaeological integrity remains preserved for future study and interpretation.
