Burnt Mound 450m ENE of Caeglas Farm is a prehistoric burnt mound situated in Wales and protected by Cadw under reference CM286. The monument consists of a heap of fire-cracked stones accumulated through repeated heating and cooling cycles, a characteristic feature of burnt mounds dating chiefly to the Bronze Age. These enigmatic structures are thought to have served various functions including cooking, water heating for ritual or domestic purposes, or metalworking processes. The site's underlying bedrock comprises Llanvirn Rocks of undifferentiated Whiterock formation, a sequence of mudstone, siltstone and sandstone deposited during the Ordovician period over 450 million years ago.
The specific geological foundation of mudstone and siltstone would have influenced both the mound's construction and its preservation. Stone selected for heating would have been gathered from local sources or deliberately chosen for its suitability to withstand thermal shock. The accumulated thermally fractured material creates the distinctive mound profile visible across the Welsh landscape, distinguishing these sites from other prehistoric monuments.
Today the burnt mound remains as tangible evidence of Bronze Age technological practice and resourcefulness. Its protection reflects the archaeological significance of such monuments in understanding prehistoric subsistence strategies and settlement patterns across the upland regions of Wales.
