The cairn dates to the Bronze Age and represents the ritual burial practices of that period, when such mounded stone structures served as communal or individual graves and functioned as enduring territorial markers within the landscape. The monument comprises a circular mound of stones, a characteristic form of Bronze Age burial construction across Wales and the broader British Isles. Such round cairns typically contained cremated human remains and occasionally grave goods, serving both as places of interment and as focal points for ritual activity and remembrance within prehistoric communities.
