Maen Melyn Standing Stone is a prehistoric upright stone monument located in Wales and protected by Cadw under the reference CM063. The stone rises from bedrock composed of Pridoli rocks—undifferentiated mudstone, siltstone and sandstone deposited during the Pridoli epoch—which provides the geological foundation for this Bronze Age or earlier landscape marker. Standing stones of this type were commonly erected across Wales during the prehistoric period, serving purposes that likely included territorial demarcation, ceremonial functions or alignment with astronomical events.
The monument's name, Maen Melyn, translates from Welsh as "yellow stone," suggesting distinctive colouring visible to those who named or recognised it in the landscape. Its survival to the present day, despite millennia of exposure to Wales's often severe weather, reflects both the durability of its stone material and the cultural significance that has preserved it through successive generations. The site's inclusion in the Cadw register ensures its protection as a key element of Wales's prehistoric heritage and tangible connection to its ancient communities.
