Cefn Ty-Mawr is a prehistoric round cairn situated in Wales and protected as a scheduled ancient monument by Cadw under reference BR097. The monument sits upon bedrock of Ashgill age, where mudstone, siltstone and sandstone strata form the underlying geology of the site. This type of stone-built mound was constructed during the Neolithic or Bronze Age, serving as a communal or individual burial place for members of prehistoric communities. Round cairns are among Wales's most enduring monuments, built from locally gathered stone and often positioned on elevated ground to dominate the surrounding landscape. The Ashgill rocks beneath Cefn Ty-Mawr would have provided the builder with ready access to suitable stone for construction. The monument remains a tangible connection to Wales's early prehistoric past and continues to inform understanding of burial practices and settlement patterns in the prehistoric period.
