Ty'n-yr-Eithin Round Cairn is a prehistoric round cairn located in Wales and protected by Cadw under reference CD226. The monument sits upon bedrock of Llandovery age, comprising sandstone and conglomerate deposits laid down in orderly interbedded sequences. This solid geological foundation of mixed sedimentary stone would have been familiar to the prehistoric communities who built the cairn, and fragments of local stone form the structure itself.
Round cairns of this type were typically constructed during the Bronze Age as burial monuments or ceremonial structures. The stacked stones, gathered from the immediate landscape, would have created a distinctive mound visible across the surrounding terrain. The choice of location on stable bedrock ensured the cairn's structural integrity over millennia, allowing it to survive as a recognisable earthwork.
Today, Ty'n-yr-Eithin Round Cairn remains an important record of prehistoric settlement and burial practice in Wales. Its protection under Cadw reflects its archaeological significance as a tangible link to Bronze Age communities who shaped the Welsh landscape. The monument's survival depends upon careful stewardship and continued recognition of its cultural value to Wales's heritage.
