Castle-Lloyd Round Barrow is a prehistoric round barrow located in Wales and protected as a scheduled monument by Cadw under reference CM140. The barrow sits upon bedrock of Pridoli Rocks, undifferentiated strata comprising mudstone, siltstone and sandstone laid down during the Pridoli epoch. This geological foundation would have provided a firm base for the monument's construction and remains stable beneath the accumulated soils and deposits of the intervening millennia.
Round barrows of this type date to the Bronze Age and served as burial monuments for prominent members of prehistoric communities. The mound would originally have been more prominent than its current form, constructed by heaping stone and earth over a central burial chamber or grave. The Pridoli bedrock's variable composition of fine-grained sediments would have influenced both the appearance and stability of material available locally for the barrow's construction.
The monument's survival to the present day, despite the passage of more than three thousand years, testifies to the solid engineering of Bronze Age builders. Its protected status ensures that this important archaeological record of Wales's prehistoric past remains preserved for future study and public appreciation.
