Cefn Clawdd Cairn (East) is a prehistoric round cairn located in Wales and protected as an ancient monument by Cadw under reference BR402. The monument sits upon bedrock formed from Pridoli rocks—undifferentiated mudstone, siltstone and sandstone laid down during the Pridoli epoch. These sedimentary foundations would have been well established in the landscape for hundreds of millions of years before the cairn's construction during the Bronze Age or earlier prehistoric period.
Round cairns of this type typically served as burial monuments, their stone mounds marking the resting places of individuals of significance within their communities. The construction of such monuments required substantial labour and organisation, reflecting the social structures and ritual practices of prehistoric Welsh societies. The choice of this hilltop location would have made the cairn a prominent landmark visible across the surrounding terrain.
The survival of Cefn Clawdd Cairn (East) to the present day, despite millennia of exposure to weathering and potential disturbance, testifies to the durability of stone construction. Its protection under Cadw recognises the monument's archaeological importance as evidence of prehistoric settlement, burial practices and landscape use in this region of Wales. The cairn remains a tangible link to the communities who built it and the wider Bronze Age heritage of Wales.
