Trichrug Round Barrows is a prehistoric round barrow in Wales protected by Cadw under reference CM090. Dating to the Bronze Age, this earthwork monument rises from bedrock of Ashgill composition—mudstone, siltstone and sandstone laid down in the Ordovician period. Round barrows of this age typically served as burial monuments for individuals of status, constructed by heaping earth and stone over a central interment, and often clustered in groups across suitable upland terrain. The geological foundation here, characteristic of much of Wales, would have provided both loose rubble suitable for cairn construction and the elevated, well-drained landscape that communities traditionally chose for such prominent ceremonial sites. The monument's survival into the present day, despite centuries of agricultural use and weathering, testifies to the substantial labour invested in its original construction.
