Round Cairn 500m SE of Moel Seisiog is a prehistoric kerb cairn situated on the upland slopes of Wales. The monument consists of a circular pile of stone, originally defined by a perimeter kerb of larger stones that once marked its outer boundary. Built upon bedrock of Wenlock sandstone and conglomerate, the cairn would have been constructed by prehistoric communities using locally available stone from the surrounding landscape.
Kerb cairns of this type typically date to the Bronze Age and served as prominent burial monuments across upland Britain and Wales. The substantial foundation of weathered Wenlock rock beneath the site would have provided a stable base for construction, whilst the interbedded sandstone and conglomerate naturally fractured into workable blocks suitable for cairn-building. Over millennia, stone robbing and natural weathering have altered the monument's appearance, though its kerb-defined form remains archaeologically distinctive.
The cairn has been recorded as a protected monument by Cadw, the Welsh Heritage Monuments service, under the reference DE307. Its survival on these open moorlands reflects the enduring archaeological value of upland monuments, where such structures often remain more visible and less disturbed than their lowland counterparts, providing important evidence of prehistoric settlement and funerary practice in Wales.
