Llyn Cyfnwy Round Barrow is a prehistoric burial mound of Bronze Age date, located in Wales and protected as a scheduled monument by Cadw under reference DE064. Round barrows of this type typically date between 2200 and 1500 BC and served as high-status burial places for individuals and small family groups. The mound would originally have been more prominent than its current form, constructed over a central grave or cremation pit containing the earthly remains of the deceased, often accompanied by grave goods such as pottery, metalwork or flint.
The barrow is sited upon bedrock of the Millstone Grit Group, a Namurian formation comprising interbedded mudstone, siltstone and sandstone. This geology is characteristic of the Carboniferous upland terrain across much of Wales, where prehistoric communities established their burial monuments on naturally elevated ground. The choice of location on higher ground was typical of Bronze Age funerary practice, positioning the burial place visibly within the landscape.
The surviving earthwork represents one of many similar monuments constructed across the Welsh uplands during the Bronze Age. Barrows such as this offer important evidence for prehistoric settlement patterns, land use and beliefs surrounding death and commemoration in ancient Wales.
