Carnedd Das Eithin Round Cairn is a prehistoric round cairn situated in Wales and protected as a scheduled ancient monument by Cadw under reference MG271. Round cairns of this type were constructed during the Bronze Age as burial monuments, typically serving as focal points for ritual activity and community identity across the upland landscape. The cairn's construction and longevity reflect the enduring importance of monumental burial practices in prehistoric Wales.
The monument rests upon bedrock composed of Ordovician felsic tuff, an extrusive volcanic rock formed during the Ordovician period over 440 million years ago. This ancient geological foundation provided the parent material from which stones for the cairn's construction could have been derived. The volcanic character of the underlying geology would have shaped both the availability of building materials and the visual character of the surrounding landscape.
The site's upland setting in Wales situates it within a region rich in prehistoric monument complexes. Round cairns frequently occupy prominent positions across such terrain, serving as durable markers visible across considerable distances. The cairn's survival to the present day, now under official protection, reflects its robust construction and the relative stability of upland environments. Such monuments remain important sources of evidence for understanding Bronze Age settlement patterns, burial practices and territorial organisation in prehistoric Wales.
