Maen Llwyd Standing Stone is a prehistoric standing stone located in Wales and protected by Cadw under reference CM064. As a monument of this type, it likely served ceremonial, territorial or burial-marking functions during the Bronze or Neolithic period, though the exact date of its erection remains unknown. Standing stones represent some of Britain's most enduring monuments, often positioned to be visible across considerable distances across the landscape.
The stone rises from bedrock composed of Pridoli rocks—mudstone, siltstone and sandstone laid down in the Pridoli period of the Palaeozoic era, millions of years before human settlement. The geological character of this foundation would have influenced both the stone's stability and the labour required to raise it. The Pridoli sequence in this region creates a distinctive landscape that shaped Bronze Age and Neolithic settlement patterns.
Like many Welsh standing stones, Maen Llwyd's original purpose can only be inferred from its form and positioning within the wider ceremonial landscape. Its survival to the present day, protected and recorded by Cadw, ensures this monument remains accessible for archaeological study and public engagement with Wales's deep prehistory.
