Corndon Hill Round Cairns is a prehistoric round cairn located in Wales and protected by Cadw under reference MG111. The monument sits upon bedrock formed during the Silurian period, consisting of an unnamed mafic igneous intrusion of Ordovician to Silurian age. This dark, heavy volcanic rock would have been exposed or near the surface when the cairn was constructed, providing readily available stone for building.
Round cairns of this type typically date to the Bronze Age and served as burial monuments, often marking the graves of individuals of status within their communities. The construction of such cairns on Corndon Hill would have taken advantage of the natural stone supply offered by the igneous bedrock beneath the site. The cairn's prominent hilltop location would have made it visible across the surrounding landscape, serving as a lasting marker within the Bronze Age ceremonial and territorial geography of the region.
Today the monument remains a significant archaeological record of prehistoric Wales, preserved within the upland terrain that has changed little since its construction thousands of years ago.
